Bus Ducts are used for tall buildings, Industries etc as a substitute to cables for conducting currents of 400 A to over 7000 A.
Companies like GE, Square D, ABB, Continental etc make Bus Ducts.
We are planning to make Bus Bars, which is the main active component of a Bus Duct.
I am looking for specs of the bus bars required by these companies. Specifically, whether they use bus bars in soft / Annealed or Semi Hard condition.
Can anyone guide me about how to approach these large companies to get their purchase specs?
Thanks.
