In the power system, the busbar connects the various current-carrying branch circuits in the power distribution device, and plays the role of collecting, distributing and transmitting electrical energy. The busbars are roughly divided into the following three categories according to their appearance and structure:
Hard busbar: including rectangular busbar, circular busbar, tubular busbar, etc.
Soft busbar: including aluminum stranded wire, copper stranded wire, steel core aluminum stranded wire, expanded diameter hollow conductor, etc.
