1.
|
All the busbars & busbar supports are designed to withstand necessary short circuit levels the size of the busbar insulator
|
|
|
|
distance between insulator is designed to carry rated currents at 50 degree centigrade ambient with maximum Temperature rise of 30 degree centigrade. |
|
|
2.
|
Necessary precaution is taken for busbar just including cleaning by sandpaper & application of petroleum jelly for protection against oxidation (for Aluminum busbar only ) |
|
|
3.
|
The number of hole in the busbar is kept to petroleum jelly for is kept to minimum. The loss in using additional cross selection of busbar completeness area. |
|
|
4.
|
The joint of busbar have sufficient overlaps or additional strips. |
|
|
5.
|
The busbar supports are usually of SMC & DMC. |
|
|
6.
|
The complete busbar system is independently supported so that no load Can transferred to switch gear components. |
|
|
7.
|
The bending of busbar is done using hydraulic machine so that no cracks are developed & deformation is minimum. |
|
|
8.
|
Suitable spacing is maintained between the busbars |
|
|
9.
|
The busbars are insolated with the heat shrinkable sleeves. |
|
|
10.
|
Wherever necessary the busbar is shrouded to avoided the human touch. |
