Anti-winding wire and cable

Technical Field

The utility model relates to the technical field of wires and cables, in particular to an anti-winding wire and cable.

Background

Wire and cable are used for transmitting electric energy, information and wire products for realizing electromagnetic energy conversion, wire and cable in a broad sense is also called as cable for short, cable in a narrow sense is insulated cable, and it can be defined as: an aggregate consisting of; one or more insulated wire cores, and their respective possible coatings, total protective layers and outer sheaths, the cable may also have additional conductors without insulation.

The current electric wire and cable twine with other electric wire and cable easily and knot at the laying process, not only be not convenient for separate, be not convenient for lay, reduce electric wire and cable practicality, in addition, electric wire and cable is at the circular telegram operation in-process, often can suffer from the impact load of heavy current or suffer from the short-circuit current impact that leads to because of the consumer breaks down, and then produce more heat in the short time, thereby cause the temperature variation of insulating layer great, and the more rapid temperature variation can lead to the accelerated aging of insulating layer, and then reduce whole electric wire and cable's life.

Based on this, utility model has designed an antiwind wire and cable to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an antiwind wire and cable, for realizing above-mentioned purpose, the utility model provides a following technical scheme: its structure includes the cable body, the shaping has on a cable body lateral wall the lug, the shaping has on another lateral wall of cable body the recess, the cable body is embedded to have the sinle silk cover of fixed sinle silk, the sinle silk cover is provided with the isolation layer, be equipped with the filler between isolation layer and the sinle silk cover, the surface of isolation layer is provided with the heat insulation layer, the surface of isolation layer forms the arch of a plurality of array distributions, the arch makes the isolation layer with form the clearance between the heat insulation layer, the surface of heat insulation layer is provided with the outer insulation layer, the heat insulation layer with still be provided with corrosion resistant layer between the outer insulation layer.

Preferably, the wire core sleeve is made of an insulating material.

Preferably, the outer surface of the wire core sleeve is provided with a shielding layer.

Preferably, the filler is a nylon fabric.

Preferably, the isolation layer is a silicone rubber layer, and the heat insulation layer is a crosslinked polyethylene layer.

The utility model has the technical effects and advantages that: according to the utility model, the bulges and the grooves are arranged and have corresponding specifications, so that two adjacent cables can be integrated and then laid side by side in the cabling process, winding and knotting are avoided, the laying is convenient, the laying efficiency and the practicability of electric wires and cables are improved, meanwhile, a certain gap is formed between the heat insulation layer and the isolation layer due to the bulges of the isolation layer, the contact area between the heat insulation layer and the isolation layer is reduced, the heat insulation layer and the isolation layer slow down the heat transfer speed generated when a wire core is impacted by current, the relative stability of the temperature of the inner insulation layer and the temperature of the outer insulation layer is ensured, and the problem that the temperature of the insulation layer is changed too fast is solved.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the description below are only some embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without inventive work.

FIG. 1 is a schematic view of an anti-wind electric wire and cable according to the present invention;
