Abstract

The invention discloses a rare earth aluminum alloy frequency conversion cable and a manufacturing method thereof. The cable is composed of rare earth aluminum alloy conductor, insulating layer made of crosslinked polyethylene mixture, liner tape made of non-woven material, composite shield layer and outer protective layer made of polyvinyl chloride material. The rare earth aluminum alloy conductor is composed of Al, Zn, Mg, Cu, Si, Fe, Mn, Sr and rare earth elements. The composite shielding layer comprises a copper wire braided shielding layer and a copper tape shielding layer. The number ofrare earth aluminum alloy conductors is not less than 3, and each bundle is stranded by not less than 30 rare earth aluminum alloy wires. A manufacture method comprises smelt, casting, pressing, drawing, anneal, stranding, extruding insulation layer, stranding, wrapping, composite shield layer processing and extruding outer protective layer. The invention aims at the technical problems of low conductivity, poor flexibility, poor shielding performance and the like in the prior art. The invention has the advantages of high conductivity, good voltage shock resistance, good shielding performance and the like.

Description

technical field [0001] The invention relates to the field of aluminum alloy cables, in particular to a rare earth aluminum alloy frequency conversion cable and a manufacturing method thereof. Background technique [0002] Frequency conversion cables are suitable for power supply cables or electrical connections in frequency conversion control systems with AC rated voltages of 0.6 / 1KV and below, and are widely used in metallurgy, electric power, petrochemical and other industries. Among the existing frequency conversion cables, copper cables, aluminum cables and aluminum alloy cables are commonly used. As we all know, copper cables have many advantages in terms of electrical, mechanical, and durability, but the price of copper is much higher than that of aluminum. For a long time, the price of copper The price is more than three times that of aluminum; at the same time, based on the substantial increase in the demand for cables based on the development of electrification, inf...
