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.
