Rated voltage 0.6/1kV aluminum alloy core coaxial cable

product structure

product features

1) The cable is made of an inner conductor made of stranded 8000 series aluminum alloy single wires, a cross-linked polyethylene insulation layer, an outer conductor made of 8000 series aluminum alloy single wires uniformly wound, a polyester tape wrapped, and a 90℃ ultraviolet resistant polyvinyl chloride outer protective layer.

2) Cross-linked polyethylene has excellent thermal resistance, increasing the aging resistance of insulation, and greatly increasing the life.

3) Through conductor alloying, improve the electrical conductivity, thermal creep resistance, corrosion resistance and stability of aluminum conductors, reduce transmission line loss, and improve the reliability of wires and cables.

4) The coaxial cable has stable structure and good cable roundness.

5) Compared with ordinary low-voltage cable structures, the cable diameter can be reduced, the cable material investment can be reduced, the insulation material can be reduced by 50%, and the sheath can be reduced by 40.3%, which reduces production costs.

6) The concentric conductor of the cable is not only a neutral or grounded conductor, but also a shielding layer with excellent shielding performance.
