Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a double-layered, dense busbar. Background Technology

[0002] Compact busbar trunking is suitable for AC three-phase four-wire and three-phase five-wire systems with a frequency of 50-60Hz, a rated voltage up to 690V, and a rated operating current of 250-5000A. It serves as an auxiliary device for power distribution equipment in industrial and mining enterprises and high-rise buildings, and is particularly suitable for the renovation of workshops and old enterprises.

[0003] Chinese patent discloses a double-layered dense busbar trunking, including a housing, a cover plate provided on the inner side of the housing surface, a fixing screw connecting the cover plate and the housing, a pressure plate provided on the surface of the fixing screw, and an installation rod penetrating one end of the pressure plate.
