Description

Five-core corrugated wire and cable

1. Technical field

The utility model relates to a wire and cable, in particular to a five-core corrugated wire and cable.

2. Background technology

Wires and cables are necessary for communication and power transmission. At present, traditional five-core wires and cables are usually made of a single material, and the round cores processed are not compact enough. Due to its structural problems, the electrical performance of the conductive core of the produced wire and cable is not stable enough. The consumption of raw materials is large, the appearance is not round enough, and the use is not satisfactory, so its improvement and innovation are imperative.

3. Contents of utility model

In view of the above situation, in order to overcome the defects of the prior art, the purpose of this utility model is to provide a five-core corrugated wire and cable, which can effectively solve the problem of insufficient compactness of the existing five-core corrugated wire and cable, and the electrical performance of the conductive core. The problem of insufficient stability and large consumption of raw materials, the technical solution of the utility model is that the utility model includes a conductor, an insulating layer and an insulating outer protective layer, and the inner center of the insulating outer protective layer has a conductor with a circular cross section, and the cross section is circular There are four corrugated conductors evenly distributed around the conductor, and the circular conductor and each corrugated conductor have an insulating layer outside, and are closely combined to form a five-core wire and cable structure. The utility model is simple in structure, novel and unique, and changes the circular compression structure adopted by the original five-core wire and cable, so that the electrical performance of the conductive core of the wire and cable is more stable, and due to the adjustment of the product structure, it can be used in the production process of the product. Among them, a large number of filling materials are omitted, which makes the appearance of the cable more compact and round, which well meets the construction needs in various environments. It is durable, has good use effects, long life, less maintenance, and significant economic and social benefits.

4. Description of drawings

Accompanying drawing is the structural representation of the utility model.

5. Specific implementation

Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in detail.

As shown in the drawings, the utility model includes a conductor, an insulating layer and an insulating outer protective layer. The inner center of the insulating outer protective layer 5 has a conductor 6 with a circular cross section. A conductor 1 with a corrugated cross section, a conductor 6 with a circular cross section and an insulating layer 2 outside each conductor 1 with a corrugated cross section are closely combined to form a five-core wire and cable structure.

In order to ensure the use effect, there is an armor layer 4 and a buffer layer 3 sequentially from the outside to the inside between the insulating outer protective layer 5 and the four corrugated conductors 1 .

It can be seen from the above structure that the utility model has a compact structure, does not require fillers, is low in cost, and is firmly fixed between each conductor. Long and safe, it is an innovation in wire and cable, with remarkable economic and social benefits.
