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

Steel cored aluminum stranded wire acts as composite overhead conductor. It mixes inner steel core and outer aluminum strands.

It serves high voltage and ultra-high voltage power transmission lines widely.

The inner steel core delivers strong tensile force. It handles long spans, heavy ice and strong wind zones.

Outer aluminum strands secure smooth power conduction. It supports efficient long-distance power delivery.

We supply multiple variants for diverse working conditions. Main types include ACSR, ACSR/GA and ACSR/AW.

Each type matches different corrosion levels and mechanical load standards.

It becomes the top pick for crossing rivers, canyons and long-span overhead projects.

Working temperature limits vary by wire type. Long-term safe temperature ranges from 75℃ to 100℃.

Short circuit temperature within 5 seconds cannot go over 200℃.

This wire resists fatigue and creep well. It stays stable under repeated outdoor loads.

Engineers pick different steel core grades and aluminum-steel ratios. The choice balances power capacity and tower construction costs.
