OEM Insulated Power Welding High Current Copper Flexible Laminated Electrical Shunts

Copper Laminated Flexible Shunts are made from electrolytic grade copper foil. The copper foils are stacked together and by a special diffusion method solidified at the contact areas. There is no filler metal used to form the solid portion and the metal itself melts and forms homogeneous bonds. Thus, there is almost nil, million drop in the connectors making it a perfect substitute of the solid busbar.These are made using a press welding procedure where individual copper strips are fused through applying direct current as well as pressure without the need of foreign material.The raw material that is used to manufacture our copper laminated shunts products is LME grade 'A' cathodes of purity greater than 99.99% copper resulting in higher conductivity, crack free extrusion, excellent finish, and longer life.Copper shunts are widely useful in electrolytic processes. Copper flexible shunts are also used in new energy, electric vehciles,transformer and rectifiers, resistance welding, switch gear, telecommunication etc.Copper laminated flexible shunts are individually designed and manufactured in accordance with the customer's requirement. We are known for our timely service, fast delivery and plating quality in the market. This has led to successful alliances with major electrical and energy companies in RHI .
