What is an electrical copper busbar

Copper busbar refers to the copper bar or aluminum bar connecting the main switch in the electric cabinet and the switch in each branch circuit in the power supply system. The surface has insulation treatment, which is mainly used as conductor. The main power supply line of the distribution power supply device (copper bar and aluminum bar are called bus bar), and each branch line (branch bar) is led up and down from the bus bar. Sometimes called bus bar, it is the name of conductive material on power distribution equipment. It is made of copper (equivalent to wire), has no insulating layer, and is painted with color paint indicating phase sequence. It is mainly used for indoor transformer, distribution cabinet, power main switch and then connected to each switch. Copper conductive systems suppliers -CHNZBTECH

The busbar provides the electrical connection between the power cables and the electrode holder. Bus-bars consist of a rigid, round, copper pipe. Typically the bus tube is supported by one or two bolted connections. Good insulation must be installed between the bus tube and its' supporting members to ensure that arcing which could destroy the bust tube does not take place. Bus tubes are usually attached to the power cables using removable, cast copper terminals or in some cases, permanent fabricated copper terminal plates and pads Several configurations are available for the bus tube termination at the electrode holder and contact pad. These include flanged connection to the contact pad, flat blade joined to the tube for parallel connection with the holder and a round copper tube contact point with the connector. The bus tubes may be bolted to the holder or contact pad or a fused permanent joint may be used. Copper busbar system chosen large section for water-cooled copper pipe group, made the resistance and reactance of per phases high current system as minimum, at meantime balanced reactance for three phases.
