Product Description

Introduction: The cable paper-covered wire includes cable paper covered aluminum wires and cable paper covered copper wires. They are made of oxygen-free copper rods or electrical round aluminum rods that are annealed after being extruded or drawn by a specification die, and then wrapped two or more layers on the copper (aluminum) conductor Insulating paper (including telephone paper, cable paper, high-voltage cable paper, turn-to-turn insulation paper, etc.) winding wire, suitable for oil-immersed transformer coils and other similar electrical winding wires. The bare copper (aluminum) conductors produced by the extrusion process are ideal materials for the production of cable paper covered wires.

Executive standard: GB/T7673-2008

Cable Paper Covered Aluminum wire Material:

The Flat aluminum wire should meet the requirements of GB5584.3-2009, and the resistivity at 20°C should not be greater than 0.0280Ωmm2/m

The rectangular copper wire shall comply with the regulations of GB5584.2-2009, and the resistivity at 20°C shall not be greater than 0.017241Ωmm2/m

The insulation thickness of the paper-coated round (flat) wire shall meet the following requirements or be negotiated by the supplier and the buyer:
