Busbars, with their high power capacity, safety, reliability, and ease of installation, have experienced rapid development in China since their introduction in the 1980s, driven by the country's booming engineering and construction industry.
Busbars, with their large power capacity, safety, reliability, and ease of installation, have experienced rapid development in China since their introduction in the 1980s, driven by the country's rapid engineering construction progress.
In high-rise building power supply systems, the main power supply lines play a crucial role, similar to the aorta in the human body; any malfunction can lead to serious consequences. Therefore, manufacturing, construction, and research units have always strived to improve the reliability of main power supply lines, constantly innovating to create new products that are easy to install and maintain, high-quality and cost-effective, and functionally stable.
Indoor wiring methods can be divided into: Exposed wiring—wires are directly or within conduits, trunking, etc., installed on the surface of walls, ceilings, trusses, and supports; Concealed wiring—wires are installed within conduits, trunking, etc., inside walls, ceilings, floors, and floor slabs, or within holes in cement boards. For small buildings with low power loads, the main lines often use insulated wires; for high-rise buildings with larger power loads, insulated wires are insufficient to meet power demands, requiring cables or busbars for the main lines.
Before the 1980s, the main power supply lines in high-rise buildings primarily used reliable ordinary cables, installed along walls in electrical shafts using brackets or cable trays. Cables, as main power supply lines, are much safer and more reliable than bare conductors or bare busbars, but their current-carrying capacity is limited; cable cross-sections cannot be made too large (maximum 400mm2), and excessively thick cables are difficult to install. In the mid-to-late 1980s, with rapid urban development and the construction of numerous high-rise and super-high-rise buildings, power loads increased dramatically, highlighting the limitations of cables as main power supply lines, especially the significant difficulty in manufacturing cable branch connectors. A high-capacity, easily branched main power supply line was urgently needed. At this time, high-capacity, easily branched busbars were introduced from overseas and quickly gained widespread application in engineering projects.
