Abstract
The utility model relates to a three-layer insulated stranded wire, which comprises a plurality of copper conductors, two polyester insulating layers and a polyamide resin insulating layer. The two polyester insulating layers are respectively extruded outside a plurality of copper conductors. The polyamide resin insulating layer is extruded outside the two polyester insulating layers. Compared with the prior art, the utility model can be used as the connecting wire of the electric apparatus, has small outer diameter and light weight, can improve wiring density so as to save space, has excellent high temperature resistance, cracking resistance, high voltage resistance and solvent resistance, can resist corrosion of acid, alkali, oil and impregnating varnish, has good reliability, has an allowed long-period working temperature between minus 40 DEG C and 130 DEG C, can be straight welded, and is suitable for the connection of the electric apparatus.
Description
Technical field
The utility model relates to cable, particularly relates to a kind of three-layer insulated twisted wire.
Background technology
Be used in electric device wire connecting cable at present, by copper conductor single line or twisted wire, polyvinyl chloride is used in insulation, crosslinked polyethylene, and extrude simultaneously with interior external shield.The tradition electric wire outside diameter of cable is big, and temperature resistant grade low (70 ℃, 90 ℃), proof voltage are low, make the electrical cable external diameter very big, can't satisfy electric device miniaturization, heatproof, withstand voltage requirement.
Summary of the invention
Technical problem to be solved in the utility model is exactly to provide a kind of three-layer insulated twisted wire for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of three-layer insulated twisted wire, it is characterized in that, comprise many copper conductors, two layers polyester insulating barrier and polyamide insulating barrier, described two layers polyester insulating barrier extrudes successively outside many copper conductors, and described polyamide insulating barrier extrudes outside the two layers polyester insulating barrier.
Described copper cash adopts the copper cash of φ 1.17mm.
Compared with prior art, the utility model can be used for the electric device connecting line, and external diameter is little, and is in light weight, can improve wiring density, thus conserve space; And heatproof height, resistance to cracking can be good, proof voltage is high, solvent resistance good, its can acid and alkali resistance, the corrosion of oil, impregnating varnish, good reliability allows long-term work temperature-40 ℃～130 ℃, and can directly weld, and is suitable for electric device and connects.
