ACSR Steel Core Aluminum Stranded Wire, High Tensile Large Span Overhead Conductor
ACSR Steel Core Aluminum Stranded Wire, High Tensile Large Span Overhead Conductor
Steel cored aluminum stranded wire (ACSR) combines high tensile strength and good conductivity, making it suitable for harsh environments such as large crossings, mountainous areas, and river crossings
It serves high voltage and ultra-high voltage power transmission lines widely.
Outer aluminum strands secure smooth power conduction. It supports efficient long-distance power delivery.
Each type matches different corrosion levels and mechanical load standards.
It becomes the top pick for crossing rivers, canyons and long-span overhead projects.
Short circuit temperature within 5 seconds cannot go over 200℃.
This wire resists fatigue and creep well. It stays stable under repeated outdoor loads.
