The conductive copper bar is known by extruding the hard aluminum copper bar

Conductive copper bars, also known as copper master bars, or copper bus bars, are made from the metal copper and are usually rectangular or chamfered (rounded) rectangular long conductors. At present, round - corner conductive copper bar is widely used in order to avoid tip discharge.

Conductive copper platoon itself at the same time with many advantages, its resistivity is very small, folding large camber, etc., and belongs to a kind of large current conductive products, suitable for high and low voltage electric appliance, switch contact, power distribution equipment, bus duct, such as electrical engineering, are widely used in metal smelting, electrochemical plating, chemical caustic soda and other large current electrolysis refining project. The quality requirements of copper bus are GB/T 5585.1-2005.

Because the metal copper has good electrical conductivity, the conductive copper row has been widely used in electrical equipment, especially in complete power distribution equipment. This product is usually used in A, B, C, N phase bus bar and PE bus bar in the distribution cabinet.

And in the practical application, usually will use the phase letter mark or is painted with phase paint to distinguish. Under normal conditions, a-phase conductive copper bars are labeled as "yellow" color, b-phase as "green" color, c-phase as "red" color, n-phase as "light blue" color, PE bus as "yellow-green" dual color.

Based on the analysis of the current application, conductive copper bar is basically used in the primary line, such as phase line, zero line, ground line will be used. The connection of primary components with large current on the electric cabinet will also use this product. For example, a row of electric cabinets are connected to each other by a main bus, and the main bus is assigned to the switch electrical (isolation switch, circuit breaker, etc.) of each side of the electric cabinets.

As users, one of the most critical factors in choosing a conductive copper bar is the carrying capacity. That is to choose the appropriate conductive copper row according to the current size, the screw at the connection must be well tightened, in case the current is too large to cause the possibility of melting copper row.
