Aluminum Covered Line Wire ACSR Conductor
Covered Line Wire are intended primary for the distribution of electrical energy under normal condition of overhead (aerial) installation and service outdoors. Approved for use on insulators for overhead circuits. Otherwise treated as a bare conductor.
The cables maintain optimal performance in typical environmental conditions while ensuring reliable power transmission across overhead networks. Their design prioritizes both electrical efficiency and mechanical durability for sustained service in aerial installations.
Application
ACSR (Aluminium Conductor Steel Reinforced) serves as a bare overhead conductor specifically engineered for primary and secondary electrical distribution systems. The conductor incorporates high-strength aluminum-alloy material that achieves an optimal strength-to-weight ratio while maintaining superior sag resistance.
Key Performance Advantages:
High Strength: Steel core provides superior mechanical strength for long-span overhead lines.
Cost-Efficiency: Combines aluminum’s conductivity with steel’s affordability.
Thermal Stability: Steel reinforcement reduces sag under high-temperature loads.
Proven Reliability: Widely adopted in global power transmission networks.
