ACSR/AS Or ACSR/AW Conductor

A: The aluminum-clad steel core has an aluminum outer layer, which contacts the aluminum conductor as the same metal, so there is no galvanic corrosion between steel and aluminum. The galvanized steel core relies on the zinc coating for corrosion protection; in humid or salt spray environments, once the zinc coating is consumed, the steel core begins to rust. In coastal or industrial pollution areas, the aluminum-clad steel core performs better in corrosion resistance than the galvanized steel core.

A: The steel core does not need to be controlled separately under the aluminum conductor temperature limit. The allowable operating temperature of the conductor depends on the aluminum conductor part and the overall structural design. The steel core of the aluminum-clad type is enclosed by an aluminum layer, so the conductor's overall allowable temperature applies during operation. The specific value follows the applicable standard.

A: The outer layer of the aluminum-clad steel core is aluminum, which is softer than steel. During stringing, avoid direct contact with sharp objects or rough ground to prevent the aluminum layer from being scratched. Once scratched, the steel core is exposed to humid environments and loses the protective effect of the aluminum layer. String at the design tension to avoid relative slippage between the steel core and aluminum wires caused by uneven tension.
