Structure and Feature

Feeder Bus Duct

●Excellent insulated conductor The uniform insulation layer of heat resistant vinyl has a very

excellent electrical and mechanical feature coupled with a

no edge conductor. The quality is stable, since the insulation

coating method is continuous extrusion.

●Compact and light weight Since the conductor and the duct are contact, then the

external dimensions are small, and the laying space can be

saved. So its weight is reduced by the improved efficiency of

each portion.

●Low voltage drop The small conductor mutual distance results small reactance

and very low voltage drop.

●High short circuit capacity The structure is very strong against the electromagnetic force

generated between the conductors, and a high short circuit

capacity can be ensured.

●Easy installation and maintenance The features of compact, light and one-touch jointing make

installation very easy.

Since the entire surface is coated with insulator, then risk

of electric shock is less and concern about insulation

deterioration caused by dust and moisture is low.

●No temperature gradient As convection is not caused inside the duct, so temperature

gradients is not induced by installation conditions such as a

vertical installation, a flatwise installation and an edgewise

installation.

●Safe against fire The insulation coating is self-extinguishing and there is no

space in the duct, then there is no risk of the flue of a fire.

●No noise The duct and conductors are integrated, and vibration sound

is not caused by a current flow.

●Less magnetic flux leakage Since phases are close each other, then external leakage

magnetic flux is small, and influences to telecommunication

lines are low.

●High clamping reliability A snap pin hole, for clamping confirmation, is perforated

at threaded part of a joint bolt, and highly reliable clamping

can be obtained by just fastening a nut with a common

wrench until the hole is exposed. No special torque control

is required, in addition multiple times of tightening and

loosening are available.

●Perfect joint system If clamping is insufficient, the snap pin hole, for clamping

confirmation, does not expose as the hole is hidden in the

nut. Then the snap pin, for clamping confirmation, cannot

be inserted. In other words, by checking the insertion of

the snap pin, for clamping confirmation, clamping can be

confirmed whether completed or not. Furthermore, a red

display plate is attached to the snap pin, for clamping

confirmation, to be able to be confirm from a long distance.

In addition, the snap pin, for clamping confirmation,

has a nut anti-loosening effect. Then additive tightening

maintenance after the installation is not required.

●Highly reliable leaf spring The thick and large size leaf spring, employed even for

vehicles, is used. Because of the sufficiently large amount

of deflection in tightening, uniform conductor contact

pressure is induced then high reliability is obtained.

●No bolt through hole in the conductor Tightening bolts are placed at parts where the conductor

is completely avoided. Then the conductor has no bolt

through hole and has high electrical and mechanical

reliability.

●Spacer has high strength Since the spacer is made of high performance materials

and has no bolt through hole, then no stress concentration

is caused. So, the spacer has high mechanical and

electrical safety.

●Earth wire is not required Earth wire is not required because structural duct each

other can be electrically connected automatically by

attaching the joint cover.

●General features of batch tightening joint ○Jointing work is simple and construction time is

shortened.

○Tightening maintenance is available during energization

and maintenance can be easily carried out.

○The structure is compact.

Actual Measurement Method

Prior to measurement, i t should be confirmed that there is no misalignment in the bus duct laying.

The distance between the V-grooves of the joint case (A) is measured.

Edgewise Elbow

The center line of the bus duct is extended with a straight tool such as a ruler.

The distance between the extended bus duct center line and the V-groove is measured.

The distance at the other side is measured in the same manner.

Flatwise Elbow

The corner point of the bus duct is extended with a straight tool such as a ruler.

The distance between the extended bus duct corner point and the V-groove is measured and the measured value is deducted by the 1/2 of the bus duct height dimension.

The V-groove line is extended with a carpenter’s square, etc.

The distance between the extended V-groove line and the V-groove on the other bus duct is measured.

The side plane of the bus duct is extended with a straight tool such as a ruler and the distance to the side plane of the other bus duct is measured.

(A)V-groove

23

＊ The measurement methods shown above are just examples. On necessity a laser device or other devices are used in combination. Our on-site measurements will be charged.

The side plane of the bus duct is extended with a straight tool such as a ruler and the distance to the side plane of the other bus duct is measured.

The V-groove line is extended with a carpenter’s square, etc. and the distance to the V-groove on the other bus duct is measured.

Flatwise Offset

The center lines of the bus ducts are extended with 2 straight tools such as rulers, and the distances from the crossing point to each V-groove are measured.

Edgewise Tee

The corner points of the bus duct are extended with 2 straight tools such as rulers and the distances from the crossing point to each V-groove are measured and the 1/2 of the bus duct height dimension is deducted from the measured values.

Flatwise Tee

The bus duct center line and the plane of the side face of the other bus duct are extended with 2 straight tools such as rulers, and the distance is measured, then the 1/2 of the bus duct height dimension is deducted from the measured value.

The V-groove position is extended with a plumb (or a carpenter’s square). The plane of the side face of the other bus duct is extended with a straight tool such as a ruler. The distance is measured and the 1/2 of the bus duct height dimension is deducted from the measured value.

The bus duct center line is extended with a straight tool such as a ruler and roll down the plumb. And distance to the V-groove of the other bus duct is measured.

6. Test and inspection after the installationAfter the completion of the bus duct installation, a person responsible for installation management (Qualified person) shall measure the entire insulation resistance values and shall confirm the completion of all the work by inspecting the entire route by the method of (1) to (8) shown below; also the person shall confirm the safety of the jointed equipments, and activate the installed system. Here, we recommend that the confirmation results of the important confirmation portions shall be recorded following the cautionary notes ravels, and store the record as the evidence.When measuring the insulation resistance, the jointed equipments shall be disconnected and, if the breaker is attached, the breaker shall be turned off.The insulation resistance value is difficult to be identified because of the difference in the route length and the ambient conditions; the value is usually 100 MΩ (500 V megger testing) approximately in the dried ambient condition. If the value is less than 10 MΩ, it is considered that there is some factors which lowering the insulation. Each jointed portion shall be checked following the joint procedure. (The confirmation can be easily performed, if the intermediate check, shown in “1-3 Installation (7)”, has been carried out.)(1) The bus duct is not damaged. There is no extreme twist or

meandering.(2) The joint components are firmly attached. All the snap pins

for clamping confirmation are attached. (3) The equipment joint bolts are firmly tightened with the

specified torque. The blue surfaces of Belleville washers face to the correct direction.

(4) The hangers support the bus duct firmly.(5) The pins are pulled out as specified in the cautionary note

label of the vertical spring hanger. The double nut portion must not be turned. (Check the marking.)

(6) Grounding is surely taken.(7) After completion of the instal lation, the transport

reinforcement brackets are removed as specified in the cautionary note label for the expansion.

(8) The branches such as the plug-in box with mccb, the tap box etc. are properly installed with the boxes which have the specified capacity (confirmation of the insertion condition and tightening torque of the bolts)

7. Maintenance and checkingThe fo l lowing maintenance and check ing are both recommended for guaranteeing safe usage of bus duct for a long time.

CAUTION

Make sure qualified personnel carries out maintenance and checking work.

CAUTION

In order to maintain the functions and safety, make sure checking is carried out as scheduled. When the system is used without making the necessary checks and maintenance, failures are generated in equipment and devices, and results in inducing serious accidents.

(1) Appearance Check Check the bus duct along its entire length to make sure

that there are no deformations, damage, smears or loose joint with the join covers, hangers and plug-in breakers, or crooks or other abnormal condition.

(2) Environmental Check The environment in which the bus duct has been installed

may change immediately following its installation. Therefore, the environment should be checked to see that water, dampness, high temperature, corrosive gas, excessive oscillation and dust have deteriorated the bus duct.

(3) Joint Check The H-P bus duct uses largely flexed leaf spring in its each

joint, so the joint has no potential to become loose due to acclimatization and aging. This means that the joint needs not be re-tightened at regular intervals. However, if during installation or storage the joint surface has been damaged or deteriorated, this will adversely affect it gradually. In such a case, it is recommended that temperature of the joint while being energized should be measured to check its status. (If the temperature of the leaf spring is roughly the same as that of the bus duct, there would be no problem.)

(4) Loading Condition Check For a Plug-in bus duct, requirement for an additional load is

anticipated after its installation. Therefore, a check should be made upon installing an additional load. To make sure that the sum of the load currents is not in excess of the capacity of the bus duct. In particular, attention should be drawn if the trunk line has been branched off by using a tee or a cross.

(5) Insulation Resistance Check Check the insulation resistance between the each

phase also between the earth and the phase. In the dry atmosphere, the insulation resistant is usually 100 MΩ approximately (500 V megger testing). It is recommended to confirm and record the magnitude of the value also the entire balance and the presence or absence of aging.

These maintenance operations are recommended to be carried out about once a year as a guide.
