Abstract

The utility model discloses an anti-vibration cable, which comprises a cable core formed by twisting a plurality of wire cores, wherein each wire core is composed of a conductor and an insulating layer outside the conductor. A sheath layer is directly extruded outside the cable core, and an aramid rope is filled in a gap among the conductor cores so as to form an anti-vibration layer. The anti-vibration cable has excellent anti-vibration performance, and can normally operate when subjected to long-term high shaking force. A manufacturing process is simple, continuous production of anti-vibration cables with a long length can be realized, and special equipment is not required.

Description

A kind of antidetonation cable

Technical field

The utility model relates to a kind of power cable, specifically is a kind of antidetonation cable.

Background technology

In the long-term occasion that moves or shake, usually use the antidetonation cable; The antidetonation cable of China generally is to adopt flexible conductor to extrude elastomeric material outward to be prepared from present; This cable sheath and conductor in the vibrations process are made load-carrying construction, and certain shake-proof ability is arranged, if but cable receives bigger shaking force for a long time; Its sheath is then torn easily, and conductor opens circuit.The lost of life of cable needs often to change and safeguard.

The utility model content

It is outstanding that the utility model technical problem to be solved provides a kind of anti-seismic performance, even receive the antidetonation cable that also can normally move than big bang power for a long time.

The described a kind of antidetonation cable of the utility model comprises the cable core that is twisted into by some cores, and said core is made up of conductor and the outer insulating barrier of conductor, outside cable core, directly extrudes the formation restrictive coating.

As the improvement of the utility model, the gap in the middle of core adds the aramid fiber rope and fills formation antidetonation layer.

The beneficial effect of the utility model:

1, the outer space of core does not add filling when stranding; Twining package tape not, protective cover material fills up the outer space of core when extruding sheath, so whole cable is integrated into an integral body; When being given a shock, make whole cable stressed, reduce the influence of vibrations cable.

2, the gap in the middle of the core adds the aramid fiber rope and fills and form the antidetonation layer when stranding, and the aramid fiber rope is made up of aramid fiber, and it has high intensity, and the weight ratio hot strength is 6 times of steel wire rope, 3 times of glass; And the serviceability temperature scope extensively can normally be moved for a long time in-196 ℃ ~ 204 ℃ scope, also has fire protection flame retarding, and in light weight, intensity is high; Modulus is high, dimensionally stable, and shrinkage is low, anti-puncturing; Anti-cutting, abrasion performance, resistance to chemical attack, advantage such as dielectricity is good.In the cable use, it bears the power of cable from horizontal and vertical aspect, and protection cable conductor and plastics are avoided destroying.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Embodiment

As shown in Figure 1; A kind of antidetonation cable of the utility model comprises the cable core that is twisted into by some cores, and core is made up of conductor 1 and the outer insulating barrier 2 of conductor; Outside cable core, directly extrude and form restrictive coating 4, the gap when extruding in the middle of core adds the filling of aramid fiber rope and forms antidetonation layer 3.Conductor is stranded forms by the 6th kind for conductor 1, and the pitch ratio of outermost layer conductor is 12.

The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection range that also should be regarded as the utility model.

Claims

1. an antidetonation cable comprises the cable core that is twisted into by some cores, and said core is made up of conductor (1) and the outer insulating barrier (2) of conductor, it is characterized in that: outside cable core, directly extrude and form restrictive coating (4).

2. antidetonation cable according to claim 1 is characterized in that: the gap in the middle of core adds the aramid fiber rope and fills formation antidetonation layer (3).
