Abstract

The invention discloses an aluminum-coated steel high-conductivity overhead insulated cable and a production process thereof. The cable sequentially comprises a 20.3% IACS aluminum-coated steel core, a 62.5% IACS hard aluminum wire, a conductor shielding layer and a weather-resistant insulated layer from inside to outside, wherein the 20.3% IACS aluminum-coated steel core is a stranded wire formed by coating the surface of a patented steel wire with an aluminum rod with the purity of 99.70%; the 62.5% IACS hard aluminum wire is formed by stranding a hard aluminum wire with the conductivity of 62.5% IACS, the tensile strength higher than 160MPa and the strength uniformity lower than 25MPa; the shielding layer is made from a crosslinked polyethylene or non-crosslinked polyethylene material; and the weather-resistant insulated layer is made from a polyethylene, polyvinyl chloride or crosslinked polyethylene material. According to the cable, a conductor adopts an aluminum-coated steel core high-conductivity aluminum stranded wire structure; the aluminum-coated steel core has electrochemical corrosion resistance and fog corrosion resistance in comparison with a general steel core; the conductor life is prolonged; and high-conductivity aluminum can effectively reduce line loss and improve power transmission efficiency.
