CN201741488U - Multi-stranded layer electric cable - Google Patents

Abstract

The utility model discloses a multi-stranded layer electric cable, which comprises a central conductor, wherein a jacket is arranged outside the central conductor, a plurality of stranded layers are arranged between thecentral conductor and the jacket, and the central conductor is coated with an anti-corrosion coating layer. With simple structure, the utility model can improve the noncorrodibility of the electric cable effectively and enlarge the application range of the electric cable greatly.

Description

A kind of many strand layer cables

Technical field

The utility model relates to field of electrical equipment, and especially the electric power cable is specially a kind of many strand layer cables.

Background technology

Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.The range of application of cable is wider, and the corrosiveness of the environment that has is stronger, needs cable to have higher anticorrosive property, and traditional cable anticorrosive property generally a little less than.

The utility model content

The purpose of this utility model provides a kind of many strand layer cables, to solve the more weak problem of traditional cable corrosion resistance.

In order to achieve the above object, the technical scheme that the utility model adopted is:

A kind of many strand layer cables comprise central conductor, and described central conductor has sheath outward, it is characterized in that: have multilayer to surround the metal strand layer of central conductor from inside to outside successively between described central conductor and the sheath, described metal strand layer is formed by many wires hinge joints; Scribble the anticorrosive paint layer on the described central conductor.

Described a kind of many strand layer cables is characterized in that: except that outermost metal strand layer, the inside and outside wall of other metal strand layers all scribbles the anticorrosive paint layer.

Described a kind of many strand layer cables is characterized in that: outermost metal strand layer inwall, the inside and outside wall of other metal strand layers all scribble the anticorrosive paint layer.

Described a kind of many strand layer cables, it is characterized in that: the inside and outside wall of each layer metal strand layer all scribbles the anticorrosive paint layer.

The utility model is simple in structure, and central conductor is formed by the tight hinge joint of many steel wires, and metal strand layer is formed by many aluminum steels hinge joints, and metal twists layer and is coated on outside the central conductor successively.At central conductor, perhaps scribble the anticorrosive paint layer on central conductor, the metal strand layer, can improve the anti-corrosive properties of cable effectively, improved the range of application of cable greatly.

Fig. 2 scribbles the structural representation of anticorrosive paint layer for the utility model structure other metal strand layers except that outermost layer.

Fig. 3 scribbles the structural representation of anticorrosive paint layer for the utility model outermost metal strand layer inwall and other metals strand layer.

Fig. 4 all scribbles the structural representation of anticorrosive paint layer for the utility model metal strand layer.

Embodiment

As shown in Figure 1.A kind of many strand layer cables, comprise by many steel wires and closely link the central conductor 1 that forms, outside the central conductor 1 sheath 2 is arranged, the two-layer metal strand layer 3 that surrounds central conductor 1 is from inside to outside successively arranged between central conductor 1 and the sheath 2, metal strand layer 3 is linked by many metal aluminum steels and forms; Scribble anticorrosive paint layer 4 on the central conductor 1.

As shown in Figure 2.Except that outermost metal strand layer, the inside and outside wall of metal strand layer of its innermost layer all scribbles the anticorrosive paint layer.

As shown in Figure 3.Outermost metal strand layer inwall, the inside and outside wall of other metal strand layers all scribble the anticorrosive paint layer.

As shown in Figure 4.The inside and outside wall of each layer metal strand layer all scribbles the anticorrosive paint layer.

Claims (4)

1. twist layer cable one kind more, comprise central conductor, described central conductor has sheath outward, it is characterized in that: have multilayer to surround the metal strand layer of central conductor from inside to outside successively between described central conductor and the sheath, described metal strand layer is formed by many wires hinge joints; Scribble the anticorrosive paint layer on the described central conductor.

2. a kind of many strand layer cables according to claim 1 is characterized in that: except that outermost metal strand layer, the inside and outside wall of other metal strand layers all scribbles the anticorrosive paint layer.

3. a kind of many strand layer cables according to claim 1 is characterized in that: outermost metal strand layer inwall, the inside and outside wall of other metal strand layers all scribble the anticorrosive paint layer.

4. a kind of many strand layer cables according to claim 1, it is characterized in that: the inside and outside wall of each layer metal strand layer all scribbles the anticorrosive paint layer.
