AACSR/EST

High Strength Aluminum-alloy Conductor, Extra-High-Strength Steel Wire Reinforced

Extra high strength steel, and high-strength aluminum alloy.
High strength/weight ratio for big span transmission, adjustable aluminum/steel ratio of cross section.
Long life span, safety under severe conditions.
Lower engineering investment, good sag performance at large span.
