Suspension clamps support and connect conductors onto insulator strings.

Information for ground wire suspension clamps, including fibre optic cables (OPGW - optical ground wires) and ADSS (all-dielec-

tric self-supporting) cables can be found in Parts 8 and 18 of the catalogue.

Suspension clamps provide the following:

- A safe mechanical connection in all conditions. This includes all

ruling span stresses at maximum working loads combined with

controlled grip of longitudinal tension that provides protection.

Suspension clamps also provide longitudinal grip control, relea-

sing the conductor at the suspension clamps at defined slip loads

to prevent damage.

- The clamps are designed to protect the conductor at line design

installation loads.

- Suspension clamps incorporate controlled movement for added

conductor protection against wind induced vibration and oscil-

lation.

- High electrical current short circuit loads are transmitted through

arcing devices attached to string hardware protecting the suspen-

sion system. For more details, please refer to Part 3 of the catalo-

gue.

- The outer profile clamp shapes are designeduce electrical dischar-

ge to below maximum specified corona extinction voltages. The-

se values are also influenced by conductor bundle configuration,

and must also be considered.

- All materials used are fully compatible with the conductor appli-

cation. For example, clamps attached to aluminium based con-

ductors are manufactured from high strength corrosion resistant

aluminium alloys.

- Unless otherwise specified, all ferrous components are hot dip-

ped galvanized acc. to EN 61284 or ISO EN 1461; Overhead

lines-requirements and tests for fittings. Where stainless steel fas-

teners are used, ISO EN 3506; Mechanical properties of corro-

sion resistant stainless steel fasteners - Part 1: Bolts, screws and

studs are specified.

- For special cases where big dynamic loads may occur at low

temperatures, fittings made of low-temperature (cryogenic)

steels are available.

- For lines constructed in higher corrosive atmospheres and

environments, the minimum zinc thickness of fittings can be

increased from 85 μ to 110 μ or 130 μ Microns. - All fitting assemblies supplied have identification marking

according to EN 61284; this includes manufactures mark and

date code, specified minimum mechanical failure load, and

1 second short circuit current withstand rating.

Counter Weights can be specified to restrict displacement angles to

maintain ground earth clearancesand avoid conductor uplift.

There are several attachment options:

- Counterweight devices can be mounted using elongated bolts.

- For vertical twin and quadruple bundles, weights can be moun-

ted onto the connecting straps.

- Counterweights can also be mounted onto conductor bundle

spacers in Jumper Loops. (See also Part 9)

- Counterweight clamp attachments may reduce earth grounding

clearances. If space restrictions apply, counterweights can be

mounted directly onto the conductor.

The following catalogue pages provide an overview of the types of suspension clamp most commonly used. For more specialised re-quirements, suspension clamp designs accommodate specific line protection features.

Controlled slip suspension clampsThis type allows controlled axial cable slip forces to be precisely adjusted to allow controlled cable release at specified loads. Axial grip and slip dis-placement is maintained following high imbalanced span loadings e.g; impact or ice shedding loads on adjacent spans.

Suspension clamps for wide-span fieldsFor longer spans, double clamp types can be specified for higher strength and reduced cable bending stresses by reducing cable angle deviation at suspension points. Saddle type suspension clamps, manufactured from high strength corrosion resistant aluminium alloys, are contoured at the cable connec-tion interface to reduce support stresses, and are also recommended for long span high line angle deviation routes. This type can also be offered

as a controlled slip load clamp.Both clamp types have proven reliability and long service life with multiple power network operators.

Suspension clamps for high-tempera-

ture conductorsAs power requirements increase, high-temperature carrying conductors with a capacity of up to 235°C will be more common.

However, the clamps used for these con-ductors must not be affected by high tem-peratures and maintain strength and me-chanical performance.

It is therefore necessary to increase the mass and surface area of clamp designs to reduce thermal stresses. This is preferably accomplished by the use of Armour Rods.

Long-term testing demonstrates the effectiveness of these develop-ments. These tests also prove suitability of different types of high temperature conductor’s e.g. where the steel core has a gap arran-ged loosely inside the conductor (e.g. GAP GZTACSR conductor).

Suspension clamps for bundle conductors, for vertical twin and

quadruple bundles

All types of clamps can be used in multiple string configuartions

with specific bundle spacings. Different types of conterweight can

be adapted for direct or indirect connection to conductors.

Special models of suspension clamps

For changing between different bundle

shapes or for substation feeds, special

designs may be necessary.

Helical Suspension UnitIn the clamping area, the conductor will be surrounded by a neoprene insert of concave shape preventing the conductor from slipping under longitudinal ten-sion. The helically formed rods wound around the neoprene insert are gripped by the main clamping body.There are two basic types available.A forged aluminium main body type, with steel axle pivots screwed and pressed into the body at the conductor centre line, easing installation. The main bodies are hinged and clamped by a conventio-nal bolt, attached by steel straps to the pivots and insulator string.A conventional cast aluminium body type is secured and connected together by a high strength aluminium strap, with a clevis bolt string attachment above the conductor.

Helical wire fittingsHelical wire fittings are made of formed round wire rods, with the ends shaped depending on the material and diameter. The formed diameters of the wires are smaller than the diameter of cable to be applied. This creates uniform radial pre compression of the spiral without permanent distortion of the wires or sub-sets. This applies the initial low stress grip of the cable, which increases as a resultant of higher tension forces that convert to high frictional grip. Uniform radial loads and grip increase over a longer application and contact length that provide low relative and uniform radial stress.

Suspension points have reinforcing rods with larger suspension clamps applied. Special short-suspension clamps or helical suppor-ting units (HSU’s) with integrated armour rods will also be used.

Identification and labelling of products are in accordance with;

IEC 61284 (Rules of behaviour with respect to possible hazards when dealing with electric equipment and equipment employing similar techniques) will either be printed on individual rod sets or stated on a label connected to the set.

The lay direction of the helical rods is normally same as that of the outermost layer of the conductor, typically right hand lay.

The material used is the same as that in the outer layer of the conductor.

The screw type bolts of these clamps have been mounted in line with the conductor axes. This will

help to improve mobility and reduce alternating bending strains caused by vibrations. In order to

minimize abrasion between the eyes and the screw type bolts, these parts are made of steel. HSU’s

(heliformed suspension units) can be used for a conductor angle of up to 30°. Conductor angles

of up to 60° will be possible if two bodies are connected by a suitable yoke plate via a combined

heliformed rod.

This is shown in part 18.Other dimensions are available upon request.

Tension clamps connect conductors to tension strings and withstand

the required mechanical holding forces.

A distinction is made between two types of tension clamps, which have

fundamental differences:

- Disconnectable clamps, such as wedge tension clamps, bolted type

tension clamps, helical dead ends and strain thimbles, can all be

adjusted;

- Compression dead end clamps, are permanent connections, and

cannot be adjusted for span, sag, or tension adjustments.

Tension clamps must fulfil the following tasks:

- A mechanical connection that safely withstands tension loads in all

operating cases. This requires a minimum mechanical failing load

force withstand to up 95% of the breaking load of the conductors

according to the relevant specification. For substation applications,

these requirements can be reduced. To reach high tension require-

ments, conductor entry clamp profiles are designed for minimum

conductor stress. Mechanical tension forces in compression dead

end clamp jumper loops are lower.

- The design of the conductor entry profile reduces risk of damage

due to wind induced movement and vibrations.

- High currents caused by short circuit events are transmitted to the

arcing devices through the string hardware. For a more detailed

explanation, please refer to Part 3 of the catalogue.

- Clamps have design profiles that reduce electrical stress and partial

discharges to control corona extinction to above defined values.

Conductor bundle configurations combined with high nominal vol-

tages at tension towers, may require fitment of corona rings.

General

Material - All materials used are fully compatible with the conductor ap-

plication. For example, wedge clamps attached to aluminium

based conductors are manufactured from high strength corrosion

resistant aluminium alloys.

- Unless otherwise specified, all ferrous components are hot dip-

ped galvanized acc. to EN 61284 or ISO EN 1461; Overhead

lines-requirements and tests for fittings. Where stainless steel

fasteners are used, ISO EN 3506; Mechanical properties of cor-

rosion resistant stainless steel fasteners - Part 1: Bolts, screws and

studs are specified.

- For special cases where big dynamic loads may occur at low

temperatures, fittings made of low-temperature (cryogenic)

steels are available.

- For lines constructed in higher corrosive atmospheres and

environments, the minimum zinc thickness of fittings can be

increased from 85 μ to 110 μ or 130 μ Microns. - All fitting assemblies supplied have identification marking

according to EN 61284; this includes manufactures mark and date

code, specified minimum mechanical failure load, and 1 second

short circuit current withstand rating.

- Eye-clevis connections are designed acc. to IEC 61471 and

DIN 48074 - Eyes and clevises; connecting dimensions, Bolts acc.

to DIN 48073 - Connecting bolts for overhead power lines. Bolt

security split pins are manufactured in stainless steel.Copper tin-

plated types can also be supplied.

Wedge tension clamps

These clamps can be used for overhead lines

and substations.

The clamping effect of the wedge tension clamp

is created by the wedge action converting ten-

sion load into compressive clamping loads.

As tension loads increase, longitudinal wedge

movement inside the housing increases clam-

ping forces and strength.

Special grease lubrication of the wedges reduces

friction increasing mechanical grip.

Clamp selection also depends on the conductor configuration. For

ACSR applications, the designs of the conductor grooves are optimised

to clamp the aluminium outer strands into the steel core providing

good mechanical grip and strength. As for conductors that are heavily

greased, there are special types with reinforced screws. For increasing

radial pressure, these wedge clamps will be provided with a special dry

coating on the sliding surfaces. Furthermore the conductor groove is

appropriately modified. If wedge tension clamps are used, the jumper

loops are usually connected by 2 or 3 parallel groove clamps.

In principle, two types are available:

Wedge tension clamps, are made of two forged bodies connected

by a hinge with corresponding wedges. These can be with or

without jumper connection. The jumper connection is forged with

one of the two wedges. If, however, conductor diameters are bigger,

it can also be connected by means of screws separately.

Stainless Steel connecting screws are supplied as standard A2 quality.

Hot dip galvanized screws can also be specified on request.

Double wedge tension clamps have two bodies made from a high-strength aluminium profile, with wedge designed as previously described. Hot dipped galvanized screws are standard, Stainless steel A2 quality screws can also be supplied. This type of clamp is suitable for smaller conductors only.

Cone type tension clamps

These clamps work in the same way as wedge

tension clamps, but the wedges are cone

shaped. Cones are available with or without

jumper conections. Depending upon the

construction of the conductors or OPGW

it can be necessary to use reinforcing rods.

Cone diameters will be calculated acc. to the

conductor dimensions.

Wedge tension clamp for instalation on site

These wedge clamps are used to fix the con-

ductor temporary while the original clamp

will be fixed.

The installation clamps are equipped with

flexible steel straps and a demounting device

and make it possible to unload the endings of

the conductor while fixing the original Com-

pression dead end clamps.

Compression dead end clamps and com-

pression joints

These clamps can be used for overhead lines

and substations, and can achieve the highest

breaking loads using compression connection

techniques.

For ACSR conductors, the internal core is

compressed separately before the electrical

connection sleeve. The clamps and joints are

made using hydraulic compression utilising

regular hexagonal dies, specified, identified

and sized for each conductor joint.

Compression positions are marked on each

joint.

Compression devices are available upon request.

Each compression joint is supplied with a tube

of contact compound grease to ensure a good

mechanical and electrical connection between

cable and connecting interfaces and prevent water ingress in expo-

sed positions. Full jointing and assembly instructions are provided,

that includes greasing application instructions.

Compression dead end clamps and joint tubes have internal coni-

cally tapers at the conductor entry as standard avoiding stress points

by providing gradual compression load application. External tube

end tapers can also be supplied.

The compression lug for the jumper shown is angled at 30° which

determines jumper cable direction. For other applications, vertical

jumper directions are required e.g. substa-

tions. This is accommodated by two 15° an-

gles, one on the dead end connecting flag,

the other on the jumper lug.By connecting the lug at opposite faces, verti-

cal or 30° jumper exit angles are made. Other

jumper exit angles are available upon request.

Hot dipped galvanised connecting screw sets

are included within the jointing kit, stainless

steel screws can also be supplied.

Compression fittings for high-temperature

carrying conductors

As power requirements increase, high-tempera-

ture carrying conductors with a capacity of up

to 235°C will be more common.

However, the clamps used for these conduc-

tors must not be affected by high tempera-

tures and maintain strength and mechanical

performance.

It is therefore necessary to increase the mass and surface area of clamp

and joint designs to reduce thermal stresses.

Long-term testing at MOSDORFER testing laboratories demonstrates

the effectiveness of these developments. These tests also prove sui-

tability of different types of high temperature conductors e.g. where

the steel core has a gap arranged loosely inside the conductor (e.g.

GAP GZTACSR conductor).

For special projects, where electrical noise reduction is required due

to cable corona discharge risks, larger diameter hollow conductors

can be used that have the same electrical current carrying capacity

and cross section as conventional conductors.

Fittings for hollow conductors can also be supplied.

Helical wire fittings

Helical wire fittings are made of formed round wire rods, with the

ends shaped depending on the material and diameter. The formed

diameters of the wires are smaller than the diameter of cable to be

applied. This creates uniform radial pre compression of the spiral

without permanent distortion of the wires or sub-sets. This applies

the initial low stress grip of the cable, which increases as a resultant

of higher tension forces that convert to high frictional grip. Uniform

radial loads and grip increase over a longer application and contact

length that provide low relative and uniform radial stress.

Helical dead ends have multiple formed wires bonded together with

a formed loop for strain thimble attachment. The inside of the helix

of all helical tension fittings have a high friction textured finish to

improve grip. The materials used are fully compatible with the cable

being applied.

Identification and labelling of products are in accordance with

IEC 61284 (Rules of behaviour with respect to possible hazards

when dealing with electric equipment and equipment employing

similar techniques) will either be printed on individual rod sets or

stated on a label connected to the set.

The lay direction of the helical rods is normally same as that of the

outermost layer of the conductor, typically right hand lay.

The material used is the same as that of the conductor.

The stated values of breaking load refer to the straps, including connecting pieces. The retaining

force of the clamp depends on the conductor con�guration.

In the articles of L.-Nr. 566.01/ ... and 566.03/ ... the straps are riveted on the wedges.

For steel and copper conductors, wedges made of steel can be inserted.

Models with other screws and/or split pins are available upon request.

Compression fittings can be supplied in many variants:

e.g.

- clamps with bore holes for the filling with grease

- with twisted connection devices for quadruple bundles

- with a welded cable lug

- with an elongated cable lug as abrasion protection for vertical two bundles - for Aluminium-Steel conductors with only one center wire clamps and joints without steel sleeve can be supplied

Compression dead end clamps and compression joints will be adapted to suit the conductor being used very ac-

curately. For this reason, we have only included the DIN conductors as well as conductors using code names which

are most commonly used.

Compression material for conductors with other material qualities or material types of aluminium can be supplied

upon request.

Clamps with other conection devices and oval eyes can also be supplied upon request.

Compression fittings for ACSR with a big steel core will be delivered with a filler sleeve.

MOSDORFER offers compression fittings with internal tube end tapers as well as external tube end tapers, the fol-

lowing pages explain the most common types.

Other types upon request. Non tension fittings are also available. Materials for copper upon request.

Parallel groove clamps provide electrical connection between

two conductors, and mainly used in jumper loops with wedge

type suspension clamps.

Other applications include branch

connection in substations, and

ground wire eart continuity con-

nections.

Parrallel groove clamps are also

used in security loops of sus-

pension strings, where sufficient

conductor stabilisation force is

required.

For safety reasons, it is recommen-

ded to mount at least two clamps

for one loop.

Special types are required for vibration dam-

ping loops of Brettelle dampers. Clamps for

Bretelle dampers see catalogue part 10.

The grooves of parallel groove clamps made

of aluminium and designed for low electrical

joint resistance and power transmission bet-

ween conductors.

The connection faces have specialised texture

surfaces to establish better electrical and me-

chanical connection.

Forged clamps have smooth outer profiles that

are particularly suited to higher voltage fields

where good corona discharge performance

is required.

Projecting ends of conductors can be pro-

tected using end caps to maintain high per-

formance.

Parallel groove clamps can be also be manufactured from extruded

aluminium alloy, and particularly suited to earth wire applications.

For power connections, this type is suitable for voltages ≤ 132kV.Clamps can also be provided with grooves of different sizes, with

a range of reducing tubes in aluminium and bimetallic material on

request (connecting Copper to Aluminium cable).

Parallel groove clamps with spacers are obtainable for all bundle

configurations.

This is advantageous at using wedge clamps for conductor tensioning.
