Application

ACSR (aluminum conductor steel reinforced) conductor is widely used in power transmission lines with various voltage levels due to its advantages such as simple structure, low cost, etc. It is also suitable for laying across rivers and valleys where special geographical teatures exist. According to different sag and tensile requirements, steel wires of different tensile strength can be used for ACSR conductor.
