Abstract

The utility model discloses a frequency conversion cable comprising main power wire cores, a silvering copper wire woven shield layer and a FEP outer sheath; the main power wire core is formed by extruding a PVC insulation layer, category 6 copper conductors or nickel-clad copper conductors, and a tension steel wire in sequence from outside-in; the four main power wire cores are twisted to form a cable core; a drainage wire is arranged in a center of the cable core; the silvering copper wire woven shield layer extrudes outside the cable core; the FEP outer sheath extrudes outside the silvering copper wire woven shield layer. The frequency conversion cable is small in outer diameter, light in weight, and anti-tension and anti-irradiation, stable in performance, and is suitable to use in environments of severe condition like high temperature and high irradiation.

Description

A kind of frequency-changing cable

Technical field

The utility model relates to cable, relates in particular to a kind of frequency-changing cable.

Background technology

Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety meets rate and domestic market occupation rate all over 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first electric wire producing country in the world.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.Frequency-changing cable is mainly used in connecting between variable frequency power supply and variable-frequency motor the cable of use, and in rated voltage 1KV and following electric line, be used as transmission of electric energy. be particularly useful for the industries such as papermaking, metallurgy, metal processing, mine, railway and food processing, frequency-changing cable application is now very extensive, also exist a lot of not enough simultaneously, such as weight is large, tension not, the problems such as not radiation proof.

Utility model content

For overcoming above-mentioned deficiency, the utility model object is to provide a kind of frequency-changing cable.

Scheme of the present utility model is as follows: a kind of frequency-changing cable, it is comprised of active force core, silver-coated copper wire woven shield and perfluoroethylene-propylene oversheath, and described active force core ecto-entad extrudes and forms with polyvinyl chloride insulation layer, six class copper conductors or nickel-clad copper conductor and tension steel wire successively; Four active force cores are twisted into cable core; Described cable core center is provided with a drainage thread; Described silver-coated copper wire woven shield is extruded in outside cable core; Described perfluoroethylene-propylene oversheath is extruded in outside silver-coated copper wire woven shield.

The beneficial effects of the utility model: it is little, lightweight to the utlity model has external diameter, tension, radiation-resistant advantage, stable performance, is applicable to use in high temperature, radiation condition rugged environment.

Accompanying drawing explanation

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

Wherein: 1, active force core; 2, tension steel wire; 3, six class copper conductors or nickel-clad copper conductor; 4, polyvinyl chloride insulation layer; 5, silver-coated copper wire woven shield; 6, perfluoroethylene-propylene oversheath; 7, drainage thread.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described further;

As shown in Figure 1, a kind of frequency-changing cable, it is comprised of active force core 1, silver-coated copper wire woven shield 5 and perfluoroethylene-propylene oversheath 6, and described active force core 1 ecto-entad extrudes and forms with polyvinyl chloride insulation layer 4, six class copper conductors or nickel-clad copper conductor 3 and tension steel wire 2 successively; Four active force cores 1 are twisted into cable core; Described cable core center is provided with a drainage thread 7; Described silver-coated copper wire woven shield 5 is extruded in outside cable core; Described perfluoroethylene-propylene oversheath 6 is extruded in outside silver-coated copper wire woven shield 5.

Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and revise; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
