The description of insulation paper covered wire

Insulation paper covered wire is a wire that is extruded or drawn by oxygen-free copper rod or electric round aluminum rod through a mold of a certain specification and is wrapped by a specific insulating material. The combined wire is composed of several winding wires or copper and aluminum wires arranged according to the specified requirements. The winding wire of Insulation paper covered wire is wrapped by a specific insulating material.

Insulation paper covered wire mainly used for winding of oil-immersed transformers, reactors and other electrical devices.
