The Role Of Busbar In Distribution Box
Busbar refers to a product made of copper or aluminum with high conductivity, used to transmit electric energy, and has the function of collecting and distributing electricity. It is the main conductor used to transmit electric energy in power stations or substations. In the power system, the busbar in High And Low Voltage Distribution Cabinets connects the various current-carrying branch circuits in the distribution device together, and plays the role of collecting, distributing and transmitting electric energy.
In the distribution box, the busbar uses copper or aluminum bars, which have high current density, low resistance, and small skin effect, and do not need to be reduced in capacity. Small voltage drop means small energy loss, which ultimately saves the user's investment. The cable core is a multi-strand thin copper wire, and its root area is larger than that of the busbar of the same current level. And its "skin effect" is serious, which reduces the current rating, increases the voltage drop, and is easy to heat up. The metal enclosed shell of the bus duct can protect the busbar from mechanical damage or animal damage, and improve the safety of the distribution box.
