Embodiment 1

[0016] Embodiment 1: anti-interference type control cable, which includes 3 groups of wire cores, an insulating layer and a protective layer covering each group of wire cores, and it also includes a central isolated wire harness, and the 3 groups of wire cores surround the central isolated wire bundle Around and tangent to it, there is a certain gap between the insulation layers of two adjacent wire cores, the central isolation wire harness is fixed with a spacer passing through the gap, and the end of the spacer is fixed to the inner surface of the protective layer. Connected, the isolator is a steel wire rope, and the steel wire rope is connected in a straight line between the protective layer and the central isolation harness.

Embodiment 2

[0017] Embodiment 2: The difference from Embodiment 1 is that the spacer is a fiber rope, and the fiber rope is connected in a straight line between the protective layer and the central isolation wire bundle.

Embodiment 3

[0018] Embodiment 3: The difference from Embodiment 1 is that the spacer is an aramid fiber rope, and the aramid fiber rope is tangent to the insulating layer of a certain wire core between the gaps, so that the aramid fiber rope is arc-shaped .

Abstract

The invention discloses an anti-interference type control cable, comprising a plurality of cores (1), covering an insulating layer (2) and a protective layer (3) outside the wire core, It also comprises a central isolation wiring harness (4) which is surrounded by and tangent to the central isolation wiring harness and which leaves a gap between the insulating layers of two adjacent wiring harnesses, the central isolation wiring harness being fixedly connected to a spacer (5) passing through the gap, the end of the spacer being fixedly connected to the inner surface of the protective layer. The invention has the beneficial effects that a central isolation wiring harness is arranged at the center of the control cable to isolate each wire core, and an isolator is arranged between the gaps between two adjacent wire cores to prevent the wire cores from contacting each other and to ensure that no electrical interference is generated between the adjacent wire cores; The opening and closing part makes the maintenance of the control cable convenient. By pulling the outer fitting part outward in the opening and closing part, the protective layer of the control cable can be smoothly opened,and the protective layer does not need to be stripped by a knife.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to control cables. Background technique [0002] Control cables are PVC insulated and PVC sheathed control cables suitable for industrial and mining enterprises, energy and transportation departments, and for controlling and protecting lines with AC rated voltage below 450 / 750 volts. Control cables have the characteristics of moisture-proof, anti-corrosion and damage-proof, and can be laid in tunnels or cable trenches. The control cable directly transmits electric energy from the power distribution point of the power system to the power connection lines of various electrical equipment and appliances. Control cables belong to cables for electrical equipment, and power cables are two of the five types of cables. Its structure is basically similar to that of power cables, including four parts: core (conductor), insulation layer, shielding layer and protective layer. The core is t...
