Bare copper strand wire

Bare copper strand wire
Product Detailed
1. CCC Chilean Cathode Copper 2. 0.4 -1.0mm or OEM 3.16 years copper wire manufacturing experience 4. Competitive price & Sho

Advantages:

1. The production workshop for the insulation lead is a double –layer full-closed and dustless one with constant temperature and humidity.

2. Mechanically paper-winding has tight layers and heightened insulation strength.

3. Compared with traditional and manual paper-winding in all transformer manufactures, we can rise up working efficiency and reduce manufacture cost of transformer.

Application:

To be used as the material of wires

Guarantee:

Implement whole production process monitoring and inspection.
