Aluminum core cable introduction

 

Aluminum core cable is a cable with aluminum as the conductor material, which has good conductivity, economy and high tensile strength. Due to the light weight of aluminum, aluminum core cable has become a heavy-duty cable in power transmission and distribution networks. High tensile strength: Aluminum core cable has good mechanical strength and is suitable for various installation methods.

4. Strong corrosion resistance: The oxide film of aluminum material can effectively protect the conductor and is suitable for environments such as buried cables and submarine cables.
