⊙ Introduction

The annealed conductor of cable paper wrapped wire is extruded or drawn from oil-free copper rod or electrical round aluminum rod with certain specification mould. Then the copper or aluminum conductor is wrapped with two layers' or more than two layers' insulation paper including telephone paper,cable paper,high voltage paper,turn-to-turn insulation paper. The product is widely applied in oil-immersed transformers and other similar electrical instruments. The electrical bare copper or aluminum wire with extrusion process is the ideal material for cable wrapped copper or aluminum wire.

⊙ Standard: GB/T7672-2008
