Abstract
The invention relates to a cold-resistant and twisting-resistant cable with a copper-clad aluminum core. The cable is composed of a single beam of guide core or multiple beams of guide cores. Each beam of guide core is stranded by one or more copper-clad aluminum conductors. The cable is characterized in that a fire-resistant mica tape winds the copper-clad aluminum core, an insulating layer containing halogen-free flame retardant is disposed outside the fire-resistant mica tape, a non-moisture-absorption insulating band wraps the cable formed by the guide core extruding the insulating layer, a chlorosulfonated polyethylene rubber jacket is disposed outside the insulating band through injection molding, and the part between the non-moisture-absorption insulating band and the insulating layer is filled with a halogen-free filling rope. The cold-resistant and twisting-resistant cable has the advantages that the temperature resistance and mechanical performance of the cable are enhanced, the problems of cable core breaking, cable whirling, insulating layer adhesion damage and jacket damage caused by the fact that the cable is insufficient in cold resistance and twisting resistance, and cable service life is prolonged.
Description
Technical field
The present invention relates to field of cables, be specifically related to a kind of copper-covered aluminum-core and resist cold resistance to torsion cable.
Background technology
Northern China and western extremely frigid zones, winter temperature is low, the time is long, the temperature difference is large sooner or later, and a lot of cable occurred that low temperature laid the phenomenon of insulation or sheath cracking.In occasion and the region of wind power generation, mostly be high wind, cold snap, natural climate is severe, higher cold-resistant requirement be it is also proposed to Wind power cable, and twist and axial displacement because blower fan tower barrel exists, therefore need to select the cable auxiliary material of antitorque dynamic, warp resistance that ductility is good, if select common power cable to be difficult to meet the cold-resistant of low high and cold region and torsion proof requirement.
Summary of the invention
For the problems referred to above, the invention provides a kind of copper-covered aluminum-core to resist cold resistance to torsion cable, adopt the insulating material of halogen-free flame retardants, chlorosulfonated polyethylene eraser sheath solves because of cold-resistant, the cable core break that torsional strength causes not, rise revolve, insulating barrier adhesion is damaged, sheath is damaged problem.Conductor adopts copper clad aluminum conductor, solves the problem of conventional conductor poor heat radiation.
For realizing above object, by the following technical solutions: copper-covered aluminum-core resists cold resistance to torsion cable, lead core or multi beam by Dan Shu to lead core stranding and form, often bundle is led core and is formed by the one or more copper clad aluminum conductor system of twisting, it is characterized in that, copper-covered aluminum-core is wound around fire-resistant isinglass belt outward, at fire-resistant isinglass belt outward for containing the insulating barrier of halogen-free flame retardants, lead wrapped non-hygroscopic insulating tape after core extruded insulation layer stranding, the outer injection moulding chlorosulfonated polyethylene eraser sheath of non-hygroscopic insulating tape, is full of Halogen gasket for packing between non-hygroscopic insulating tape and insulating barrier.
The described insulating barrier containing halogen-free flame retardants can be the polyurethane elastomer containing halogen-free flame retardants, also can be the thermoplastic elastomer (TPE) containing halogen-free flame retardants.
Beneficial effect of the present invention: after adding fire-resistant isinglass belt, fire resistance is strengthened, and the polyurethane elastomer containing halogen-free flame retardants does not produce poison gas, environmentally safe, and anti-scratch, noiselessness, long service life, reduce cost, temperature tolerance at minus 20 degrees to high temperature 120 degree, nonpoisonous and tasteless, and there is good shock resistance and anti-fatigue performance, high anti-tearing strength, the advantage of wear-resisting, weather, oil resistant.Non-moisture absorption insulating tape effectively prevents insulation and sheath adhesion.Chlorosulfonated polyethylene eraser sheath can only swellingly can not dissolve in ketone and ether, there are excellent ozone resistance, resistance to weathering, chemical resistance etc., good physical and mechanical properties, ageing-resistant performance, heat-resisting and lower temperature resistance, oil resistance, flame resistance, resistance to wear and resistance to electrical insulating property, still keep good performance under the environment of 40 degrees below zero.This cable solves because of cold-resistant, the cable core break that torsional strength causes not, rise revolve, insulating barrier adhesion is damaged, sheath is damaged problem, extend cable useful life.
