The shadow ally that connects the copper busbars! Copper spacers!

This is a copper spacer that we manufacture almost every day. Once the basic transformer is produced and passes the power-on test, it is disassembled and reassembled on-site. At that time, it is necessary to connect the existing power receiving section and the copper busbars inside. The "copper spacer" is what connects them with bolts. Of course, this spacer is also made of copper busbars, so it has excellent conductivity! Although small, it is an indispensable behind-the-scenes player. In addition, we have a wide range of processing achievements for copper busbar products with thicknesses from 3mm to 20mm for transformer manufacturers and panel manufacturers in the Tokai region, processing as much as 150 tons of copper annually as a specialized copper processing company. We have a consistent production system from order to processing, plating, and delivery/shipping, so we can respond quickly with drawings and order forms! Hand-drawn designs are acceptable! Truly, we can handle orders from just one piece! Urgent orders are welcome! (This product is a "flexible busbar," which is a power transmission component capable of controlling large currents at the substation level.)
