Characteristics and Application Research of High Conductivity Aluminum Conductor Aluminum-clad Steel Reinforced Cable
-
Abstract
Aluminum-clad steel wire has excellent performance of mechanical, electrical and anti-corrosion. By replacing Zinc-coated steel with aluminum-clad steel wire, aluminum-cad steel core aluminum stranded wire has lighter weight, smaller resistance, better anti-corrosion performance and better sag characteristics, compared to the traditional ACSR, especially suitable for coastal and heavy polluted area. Composed of 20.3%IACS aluminum-clad steel wire and high conductivity aluminum conductor, the new energy-saving conductor i. e. high conductivity aluminum conductor aluminum-clad steel reinforced cable can superpose two materials' energy-saving effect, and further reduce AC resistance about 1.6%~2.7% compared with the same specifications of the Zinc-coated steel core high conductivity aluminum cable. A typical example of 500 kV transmission line shows, JL3/LB20 and JL2/LB20 type of the new energy-saving conductor has a notable energy conservation economic effect and worth promoting.
