Arc copper foil flexible connection is also called copper expansion joint, copper flexible connection and copper strip flexible connection. It can be used for transformer installation, connection between high and low voltage switchgear, vacuum apparatus, closed bus duct, generator and bus, rectifier equipment, rectifier cabinet and isolating switch, and connection between buses. It can improve the conductivity, adjust the installation error of the equipment, and at the same time play the role of (shock absorption) work compensation, convenient test and equipment maintenance.
Curved copper foil flexible connection products are characterized by good flexibility, strong elasticity, stable and uniform silver (tin) plating, strong adhesion, high finish, corrosion resistance, long service life, small connection resistance, excessive conductivity, superior mechanical performance, etc. Copper bus is used as a copper bar to transmit current. Copper bus has good conductivity, thermal conductivity, corrosion resistance, high mechanical strength, and no low-temperature brittleness The contact surface can be tinned or silvered according to user requirements
Copper foil soft connection and bus bar are the connection devices between the whole transformer and the rectifier cabinet, which are mainly used in electrolytic aluminum plants, nonferrous metals, graphite carbon, chemical metallurgy and other industries. It is used for connection between large transformer and rectifier cabinet, rectifier cabinet and disconnector switch, and connection between bus bars. The copper expansion joint is used to prevent the switch or bus from breaking due to short circuit or cold shrinkage of the heat exchanger, and the elasticity of the expansion joint is used for protection.
