Structure and Feature Feeder Bus Duct

● Excellent insulated conductor

● No temperature gradient

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.

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.

● Compact and light weight

● Safe against fire

Since the conductor and the duct are contact, then the external dimensions are small, and the laying space can be

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.

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

● No noise

● Low voltage drop

The duct and conductors are integrated, and vibration sound is not caused by a current flow.

The small conductor mutual distance results small reactance and very low voltage drop.

● Less magnetic flux leakage

● 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.

Since phases are close each other, then external leakage magnetic flux is small, and influences to telecommunication lines are low.

● 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.

● 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

○J  ointing work is simple and construction time is shortened. ○T  ightening maintenance is available during energization and maintenance can be easily carried out. ○ The structure is compact.

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) T he 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) A fter completion of the installation, the transport reinforcement brackets are removed as specified in the cautionary note label for the expansion. (8) T he 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)

CAUTION

Make sure qualified personnel carries out maintenance and checking work.

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.
