Problems solved by technology

The outer diameter of traditional wires and cables is large, the temperature resistance level is low (70°C, 90°C), and the withstand voltage is low, which makes the outer diameter of the electrical connection wire large, which cannot meet the requirements of miniaturization, temperature resistance, and pressure resistance of electrical devices.

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] A method for manufacturing a cable with a three-layer insulated inner core, comprising the following steps:

[0016] A. Manufacture one or more three-layer insulated stranded wires. The manufacture of each three-layer insulated stranded wire includes:

[0017] Multiple copper wires are drawn, annealed and stranded, and then two layers of polyester insulating layers are extruded on the outside of the copper stranded wires through a three-head extruder, and finally polyamide resin insulating layers are extruded on both sides. Layer polyester insulation layer, forming a three-layer insulated stranded wire;

[0018] B. Twisting the three-layer insulated stranded wire with two meshed polypropylene sheath tapes;

[0019] C. Finally wrap the outermost layer with polypropylene tape.

[0020] The copper wire adopts a φ1.17mm copper wire; the three-layer insulated stra...

Abstract

The invention relates to a method for manufacturing a cable with a three-layer insulated inner core, which comprises the following steps of: A, manufacturing two three-layer insulated stranded wires, wherein each three-layer insulated stranded wire is manufactured by drawing a plurality of copper wires, quenching and stranding the drawn copper wires, sequentially extruding two polyester insulating layers outside the copper stranded wires by using a three-head extrusion molding machine, and finally extruding a polyamide resin insulating layer outside the two polyester insulating layers to forma three-layer insulated stranded wire; B, stranding the two three-layer insulated stranded wires and two polypropylene mesh sheathes; and C, finally lapping a polypropylene tape on an outermost layer. Compared with the prior art, the product manufactured by the method can be used for connecting wires of electric apparatuses, has a small external diameter, lightweight, resistance to high temperature, high resistance to cracking, resistance to high voltage, high solvent resistance, resistance to the corrosion of acid, alkali, oil and impregnating varnish, high reliability, and capability of working at the temperature of -40 to 130 DEG C for long, can increase the wiring density so as to save a space and be straightly welded, and is applicable to the connection of the electric apparatuses.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a method for manufacturing a cable with a three-layer insulating inner core. Background technique [0002] The wires and cables currently used in the connection of electrical devices are composed of single or stranded copper conductors, polyvinyl chloride and cross-linked polyethylene for insulation, and are extruded together with inner and outer shielding. Traditional wires and cables have large outer diameters, low temperature resistance (70°C, 90°C), and low voltage resistance, which make the outer diameter of electrical connecting wires large, which cannot meet the requirements of miniaturization, temperature resistance, and voltage resistance of electrical devices. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for manufacturing a temperature-resistant and pressure-resistant cable with a three-...
