Copper busbar
Copper busbar expansion joint
Electrical copper bar is a high current conductive product, suitable for high and low voltage Electrical appliances, switch contacts, power distribution equipment, bus ducts and other electrical engineering projects are also widely used in metal smelting, electrochemical plating, chemical caustic soda and other ultra-large current electrolytic smelting projects. The electrical copper bars we supply have the advantages of low resistivity and high bendability.
Copper busbar, also known as copper busbar, copper busbar or copper busbar, grounding copper bar, is made of copper material. The cross-section is rectangular or chamfered (rounded) rectangular long conductor, made of aluminum material. It is called aluminum row, which plays the role of transmitting current and connecting electrical equipment in the circuit.
Since copper has better electrical conductivity than aluminum, copper busbars are widely used in electrical equipment, especially complete sets of power distribution devices. Generally, copper is used for the phase busbars and busbars in distribution cabinets. When in use, copper busbars are generally marked with phase-color letters or painted with phase-color paint. Phase copper busbars are painted yellow, phase copper busbars are painted green, phase copper busbars are painted red, and busbar copper busbars are painted yellow and green. .
The general technical conditions of busbar expansion joints should comply with the provisions of B "General Technical Conditions for Electric Power Fittings".

Copper expansion joints, copper-aluminum soft joints and busbars are the connection devices between the transformer and the rectifier cabinet. They are mainly used in electrolytic aluminum plants, non-ferrous metals, graphite carbon, chemical metallurgy and other industries. It is used for the connection between large transformers and rectifier cabinets, rectifier cabinets and isolating knife switches, and between busbars. The copper-aluminum expansion joint is used to prevent the switch or busbar from being pulled off due to short circuit or hot and cold contraction, and uses the elasticity of the expansion joint to play a protective role. ()Using conditions Extreme maximum temperature + ℃ Extreme minimum temperature ℃ Relative maximum humidity % Copper wire soft connection is suitable for soft connection in various high and low voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches, automobiles, motorcycles and other related products. It is made of bare copper wire or tinned copper braid (stranded wire) and is made by cold pressing method. The contact surface can be tinned according to the simple diameter of the customer.: Standard product.: Pressure welding soft connection can be processed according to customer requirements ■ Pressure welding is to press the copper foil laminate parts together, using molecular diffusion welding, and heating and pressing with large current Welded to form. ■ Copper foil: to .thick. ■ The contact surface can be tin-plated or silver-plated according to user requirements. Brazing soft connection ■ Brazing is to press the copper foil lamination parts together, use silver-based brazing material, and butt-weld with the flat copper block to form. ■ Copper foil: to .thick.
