Before the 1990s, cables played an important role in the low-voltage distribution system. But since the 1990s, the busbar slot system has been gradually introduced and developed, and has quickly been widely used in construction engineering. Compared with traditional transmission equipment, it has its unique performance advantages, such as large carrying capacity, strong overload capacity, convenient separation, good heat dissipation and convenient maintenance.
The bus bar saves space, while the cable needs a lot of space. The bus groove can be controlled in the position nearest to the equipment, while the cable must be controlled in the distribution room. The bus is provided with standard mounting supports without additional support; cables must be laid with separate bridges or piping. The bus groove can last up to 50 years and is reusable. The cable is short and can not be reused. The branch interface of the bus groove can increase the tap loop, and the cable must be laid in the distribution room. The insurance cost of installing the bus is lower, while the cable is relatively high.
