Welcome to place your orders with us! Copper bars are large current-conducting products suitable for high and low-voltage electrical equipment, switch contacts, distribution equipment, busbars, and are widely used in metal smelting, electroplating, chemical alkali, and other ultra-high current electrolytic smelting projects. The electrical copper bars we supply have low resistivity and high bendability. Copper bars, also known as busbars, copper busbars, or copper busbars, are long conductors made of copper material with a rectangular or chamfered (rounded) rectangular cross-section, which play the role of transmitting current and connecting electrical equipment in the circuit. Currently, the quality requirements for copper busbars are implemented according to the GB/T 5585.1-2005 standard. Due to copper's superior conductivity compared to aluminum, copper bars are widely used in electrical equipment, especially in complete distribution systems; generally, the A, B, C, N phase busbars and PE busbars in the distribution cabinet are made of copper bars. Copper bars are usually marked with phase color letters or painted with phase color paint during use, with the A phase copper bar marked as "yellow," B phase as "green," C phase as "red," N phase as "light blue," and PE busbar as "yellow-green" dual-color. Copper bars are mainly used in primary circuits (large current phase lines, neutral lines, and ground lines all use copper bars), and the connections of high current primary components in the electrical cabinet are made with copper bars, such as the main busbar connecting between cabinets and the branch busbar distributing to the switch electrical equipment (disconnectors, circuit breakers, etc.) on each cabinet. Copper bars can be tin-plated or bare copper, and the connection points in the electrical cabinet usually require tin-plating treatment and embossing or the addition of conductive paste. Empty spaces are protected with heat-shrinkable sleeves, and some are coated with insulating paint. The main consideration for using copper bars is the current-carrying capacity; suitable copper bars should be selected based on the current size, and the screws at the connection points must be tightened.
