35kv and below composite shielding insulation aluminum tube bus is a new type of conductive material developed by our company, which is energy saving, safe and environmental friendly.It is a substitute for the traditional rectangular bus, slot bus and cable bus, and is mainly used for the connection between transformer, switch cabinet and reactor in power generation and substation. In the power, petrochemical, steel, new energy, urban rail transit and other large current workplace to do the current role.Products have been exported to South Korea, Singapore, Indonesia, Bangladesh, Saudi Arabia and other countries.
 


Main features:
● Low skin effect, high current-carrying capacity and low power loss;
●Tube conductor good heat dissipation conditions, low temperature difference;
●High permissible stress and high mechanical strength.
● Strong electrical insulation performance;
● High insulation safety factor;
● Strong resistance to electrical vibration;
● Bus structure is simple, clear layout, easy installation, less maintenance work.
