Busbar trunking is a closed metal device composed of copper or aluminum busbar columns, used to distribute large amounts of power to various components in a distributed power system. It is increasingly replacing electrical wires and cables in indoor low-voltage power transmission trunk line projects.
It is widely used in developed countries, as well as in Hong Kong and Macau. In Guangzhou, Guangdong Province, my country, over 90% of the main power lines leading from the distribution room to the floors of buildings with 12 or more floors use busbar trunking; busbar trunking is also required from 630KVA transformers to distribution cabinets.
Busbar trunking is characterized by its modular design, commercial production, small size, large capacity, short design and construction cycle, easy installation and disassembly, non-combustible nature, safety and reliability, and long service life. Busbar trunking products are suitable for three-phase four-wire and three-phase five-wire power distribution systems with AC 50Hz, rated voltage 380V, and rated current 250A-6300A.
