What are the advantages of bus duct over cable?

Compared with wires and cables, bus bars have the following advantages and disadvantages:

1. From the current carrying capacity, the current carrying capacity of wires and cables is small, while the current carrying capacity of buses is large;

2. In terms of structural form, wires and cables are flexible (inner copper core and outer insulation layer), and buses are rigid (inner hard copper bar and outer steel or aluminum alloy shell), which cannot be bent and need special elbows;

3. From the use characteristics, the installation and manufacture of wires and cables are troublesome, and each electrical equipment needs independent pay-off and wiring, while the bus bar installation is convenient and flexible, and installation errors are not easy to occur. One bus bar can be used for many point-of-use devices to obtain power at the same time.

Busbar refers to a product made of copper (copper bar) and aluminum with high conductivity, which is used to transmit electric energy and has the ability to collect and distribute electric power. The main line used to transmit electric energy in a power station or substation. Through it, the electric energy output by generators, transformers or rectifiers is transmitted to various users or other substations. Mathematically, it refers to a straight line that moves according to certain conditions to produce a surface.
