AI Technical Summary

Technical Problem

Existing rigid pre-branched busbars have poor flexibility, are difficult to install, have limited seismic performance, and are inconvenient to maintain and repair, making it difficult to meet the electrical system requirements of high-rise buildings.

Method used

The high-rise building adopts a pre-branched flexible busbar, which includes a main cable, branch cables, C-clamp connectors, branch junction boxes, and fixing clamps. The main cable and branch cables are formed by multiple strands of soft copper wire or flexible copper wires, and are equipped with an insulation layer and a sheath. The fixing clamps are connected to the wall by screws. The C-clamp connectors wrap the conductors, and the branch junction boxes wrap the branch points and cable ends.

Benefits of technology

It improves the flexibility and ease of installation of the busbar, reduces installation costs and time, enhances seismic performance, optimizes the electric field distribution, reduces corona discharge, and improves the stability and reliability of power transmission.
