High voltage cable paper wrapped copper strand wire

Product Detailed

1. CCC Chilean Cathode Copper 2. 0.4 -1.0mm or OEM 3. Thickness of paper: 0.05mm, 0.075mm 4. Good quality & Nice packing

Advantages:

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

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

Application:

Lead wire of transformer, high voltage electrical equipment

Guarantee:

Implement whole production process monitoring and inspection.
