Problems solved by technology

[0007] (4) The use of complex environmental conditions such as sun exposure, boiling water, contact with muddy water, engine oil, acid-base liquid, etc. requires certain weather resistance, oil resistance, and solvent resistance.
The core wire is arranged in a multi-layer structure with a complex structure and poor flexibility; the wear-resistant, low-adhesion and high-flexibility sheath is made of polyurethane, which has insufficient weather resistance, oil or solvent resistance, and heat deformation resistance

Embodiment

[0030] Such as figure 1 As shown, a flex-resistant multi-core control cable includes a copper conductor 1 and an insulating layer 2 , and also includes a core wire 6 composed of the copper conductor 1 and the insulating layer 2 . A filler 3 is arranged in the middle of a plurality of core wires arranged in a single layer, and the plurality of core wires and the filler 3 are stranded to form a cable core 7, and a wrapping layer 4 is arranged on the outside of the cable core 7, and an outer sheath 5 is extruded around the wrapping layer 4.

[0031] Among them: the insulating layer 2 is a low shrinkage polyvinyl chloride insulating layer; the filling 3 is a soft filling material, preferably hemp rope; the wrapping layer 4 is a non-woven wrapping layer; the outer sheath 5 is based on ethylene-propylene Oil resistant radiation crosslinked sheath.

[0032] The original single core is improved to a multi-core structure arranged in a single layer. Under the condition of ensuring the ...

Abstract

The invention belongs to the technical field of cable application and relates to a multi-core control cable, in particular to a flexing-resistant multi-core control cable which is applicable to rated voltage of 450V / 750V and particularly applicable to electric welding machines. The technical scheme includes that the flexing-resistant multi-core control cable comprises copper conductors (1) and insulating layers (2), the copper conductors (1) and the insulating layers (2) form a plurality of core wires (6), the core wires in monolayer arrangement and packing (3) among the core wires are stranded into a cable core (7), and a lapped covering (4) is arranged outside the cable core (7) and wrapped by a sheath (5) in an extruded manner. After the technical scheme is adopted, the cable core is uniform in stress, and the cable becomes flexible, good in flexibility and flexing-resistant.

Description

technical field [0001] The invention relates to a multi-core control cable, in particular to a flexure-resistant multi-core control cable. It is suitable for cables with rated voltage of 450 / 750V, especially for electric welding machine cables. The invention belongs to the technical field of cable application. Background technique [0002] Welding machine cables belong to rubber insulated cables, which are generally single-wire cores, and the conductors are oxygen-free copper. The diameter of copper wires is small and the number is large. Conductor, so the cable body of the electric welding machine is relatively thick, with hundreds of copper wires. The conductor is covered with a layer of heat-resistant polyester film for insulation. At present, domestic products generally only have a service life of 1 to 2 months. [0003] Requirements for welding machine cables: [0004] (1) Working under the conditions of low voltage and high current requires certain tolerance. ...
