Product Description

Product introduction

Extruding a layer of aluminum outside the PBT core to form an aluminum tube, the core is protected by a heat shield. This structure can reduce the electrochemical corrosion between different metal materials. It is often used for retrofitting old wirings, low voltage grade lines, and corrosive and highly polluted areas under coastal chemical environmental conditions.
