Product Description
Soft Copper Braided Wire
GB12970.3 TTR
Ramk:Can be customized
Soft copper braided wire is used for manufacturing brush products,our copper brush wire is made by high pure cathode copper rod.
The tinned type is made by electrolytic or electric tin plating process, which has high corrosion resistance.
To solve the brush pressuring sinthered at high temperature wire brush brittlet fracture problems.
Flexible copper stranded conductor's products standards:GB12970.2
Flexible copper stranded conductor's products type:TJR1 TJRX1
Flexible copper stranded conductor's products type:TJR2 TJRX2
Flexible copper stranded conductor's products type:TJR3 TJRX3
1.Better price-less expensive than copper,reducing costs of material for cable production.
2.Higher conductivity-electrical conductivity much higher than pure aluminum.
3.Lighter weight-easy to transport and install thus saves labor cost.
