Product Description


High qulity  electrical switchgear contact arm


1. Copper and aluminum combine products are new generations product.

2. The tensile and bending strength of it are outstanding, and bonding performance is also good.

3. There are no surface cracks after flattening and bending, they are the domestic new type of enery saving

    products currently.

4. Dynamic thermal stability, temperature rise and loop resistance are all compare favorably with the same

    levels of T2 copper, this is the idea products of the present electrical industry which can lower the costs.
