Product Details

Telephone Cable Paper covered insulated aluminium wire
 
 Product Details:
 Product Name:  Telephone Paper Covered Aluminium wire

 Products: Paper covered wire  by Electrical A

The paper covered insulated aluminium wire is made of an oxygen free copper rod or an electrician's circular aluminum rod after kneading or drawing  after drawing, and then winding two or more insulating paper (including telephone paper, cable paper, high pressure cable paper, interturn insulating paper, etc.) on copper (aluminum) conductor. It is suitable for oil immersed  transformer coil and other similar electrical wiring.

Aluminium Pole extrusion die by a certain size or drawn wire after annealing, and then in the aluminum  conductor wrapped more than two or two insulating paper (including paper, telephone, cable paper, high voltage cable paper, turn insulation paper) of the winding wire, suitable for oil-immersed transformers and other electrical  winding with a similar wire. Produced by the extrusion process electrical bare aluminum wire is wrapped production of the cable wire is the best material.
