BSM2 busway system possesses the common characteristics of BSM compact insulation busway series. The differences are: its conductor adopts quality electrical conductor grade aluminum conductor, therefore, the cost of it lower than that of the copper conductor, besides, the busway system proper is rather light, and it is easy to be transported and installed; the surface technology of aluminum busbar of our company is mature. Its property is basically similar to that of the copper busbar. Since copper resources in our country is mainly from import and the price of copper remains high for a long time, while our country is rather rich in aluminum resources and its price is rather low and the technology of it is approaching being mature; therefore, aluminum busway will be the main direction of the development of busbar in our country. The busway that our company has produced has been applied in many projects such as real estate, factories and hotels, etc. with excellent performance in operation.
