Aluminum flat bus bar is a type of aluminum profile made of aluminum alloy, the shape is rectangular and produced by extrusion process.
It is mainly applied in electric power industry, industrial support parts, ship materials and aviation parts, mold manufacturing.
Application of aluminum flat bus bar
aluminum flat bus bar is mainly used in electrical equipment, such as high and low voltage electrical appliances, switch contacts, power distribution equipment, and other electrical engineering. As a conductive bus, it has the advantages of low resistivity and large bendability.
