Main characteristics

Uni-IneMix switchboards are characterised by:

* complete insulation in air of all the live parts of the switchboard* possibility of being placed against thewall* segregation between the busbar and feeder compartments* possibility of constructingmany different solutions and simple extension of existing

switchboards* easily accessible apparatus controls* personnel safety guaranteed by:* segregation of the compartmentswith IP2X degree of protection.* metal segregation and earthing guaranteed by the switch-disconnector / isolator stainless

steel housing* Insulating parts with large exhaust escape routes to guarantee insulation even in rooms

with a high degree of pollution* earthling of both the structure and components.

On request, the switchboard can be fitted with a REF 542 Plus microprocessor unit. This unitcombines all the protection, control, measuring, etc. functions usually entrusted to several devices in a singlepiece of apparatus. The REF 542 Plus unit also makes it possible to dialogue with the installation control andautomation systems, allowing plant data acquisition and processing.

10/20 kV MEDIUM VOLTAGE SWITCHBOARDS

Surface treatmentThe units are made of pre-galvanized sheet. The

doors and front panels are painted grey RAL 7035. The surface

appearance is semi gloss. The standard version switchboards

have their sides made of pre-galvanized sheet (on request, RAL

7035 painted versions are available).Degrees of protection

IP2X inside the switchboardIP3X on the external housing.

Quality Assurance systemComplies with ISO 9001:2008 Standards, certified by

Lloyd Register Quality Assurance Italy.

Compartments

The structure of each unit is entirely constructed using pre-galvanizedmetal sheets. Each unit consists of

several

compartments withmetal segregations between them. Each unit is presetwith special holes for fixing to the

floor

and is provided with bottom closure fitted with special openings for medium voltage and auxiliary circuit cable

passage.

All the units fittedwith a door have an interlockwhich only allows door opening under safe conditions.

The busbar compartment is accessed from the roof or from the front by dismantling the special metal cover.

There is a special metal wiring duct in each unit to segregate the low voltage circuits from the medium voltage

circuits.

Busbar compartment (A)

This contains themain busbar system. The busbars,made of electrolytic copper, are fixed to the terminals of

the

insulation isolator or of the switch-disconnector. Insulation is guaranteed in air.

Feeder compartment (B)

This is normally segregated fromthe busbar compartment bymeans of an isolator or a switch-disconnector.

It contains the apparatus shown in the figure below.

Auxiliary circuits

A box containing all the lowvoltage apparatus normally used can be provided in front of the busbar

compartment.

In particular:

- terminal boxes,wiring ducts and cables to connect the auxiliary circuits of the unit;

- auxiliary accessories of the circuit-breaker and unit (measuring instruments, protection relays, control and

signaling devices, fuses, auxiliary circuit protection circuit-breakers, etc.)

Cable passage for inter-panel connections is made by means of special holes provided in the walls of the box

itself.

LOW VOLTAGE SWITCHBOARDS

GeneralThe low-voltage distribution fields, which are determined according to their basic type OH-D, OH-R, C, U, SK, consists of a framework structure made of adequately dimensioned metal enclosed C-sections .Their front view and size dimensions being standardized and suited on the request and needs of the customer. Field description is given below and defined according to their rated current, circuit breaker, switch and the number of outgoing feeders.Main characteristics of all fields are the following:The busbars are placed in the busbar compartment on supporting insulators in the upper side of the fields.All metal parts which are normally free of voltage are respectively galvanically connected through toothed washers and are connected to the central earthing strip passing through the fields.The surface protection is carried out by applying standard paint RAL 7035 in an up-to-date manner, thus ensuring a high degree of anti corrosion protection. The degree of protection depending both on the requirements and the conditions prevailing at the location where these fields are to be installed, may be up to IP 33

Combining these fields allows obtaining typical low-voltage distribution boards, which bear the following basic markings:- DpR - Incoming field with circuit breaker- outgoing field- DsR - Incoming field with switch - outgoing field- UDpR - Street lighting incoming field with circuit breaker- outgoing field- UDsR - Street lighting incoming field with switch - outgoing field- 2Dp2RC - Two incoming fields with circuit breaker- coupling field - two outgoing fields- 2Ds2RC - Two incoming fields with switch - coupling field - two outgoing fields- U2Dp2RC - Two street lighting incoming fields with circuit breaker- coupling field - two outgoing fields - U2Ds2RC - Two street lighting incoming fields with switch - coupling fields - two outgoing fields- D1pR - Incoming field with circuit breaker- outgoing field (inseparable)- D1sR - Incoming field with switch - outgoing field (inseparable)- UD1pR - Street lighting incoming field with circuit breaker- outgoing field (inseparable)- UD1sR - Street lighting incoming field with switch - outgoing fields (inseparable)
