Busbars

Copper/Aluminum bus bar of EC91E ELECTROLYTIC GRADE is procured from Reputed Manufacturer and cross sectional area is chosen on basis of bus bar calculation considering derating factors

• Bus bars are braced rigidly to withstand short circuit fault with SMC supports and proper bracing housed in electroplated “u” shaped channels. ELPOWER SYSTEMS

• All bus bars are insulated with PVC heat shrinkable sleeves of relevant color.

• Earth bus bar size is determined with earth fault calculation and run throughout the panel and connected with every door/ clamp of metallic switch gear body mounted. Assembling
