Abstract

The utility model relates to an anti-static ultra high voltage silicone rubber cable, comprising conductors and insulating layers, wherein each conductor is wrapped with one insulating layer, and each insulating layer is extruded with an inner sheath; each inner sheath is wrapped with a No.1 current guiding sleeve, and the inner sheaths are used for protecting the insulating layers and the conductors; each No.1 current guiding sleeve is wrapped with a wire core sheath; the plurality of wire core sheaths are stranded to form a cable core; and the cable core is sequentially wrapped with a shielding layer, a No.2 current guiding sleeve, a breakdown resisting layer and an outer sheath from inside to outside. The anti-static ultra high voltage silicone rubber cable has the advantages of reasonable structural design, long service life, good voltage resistance and the like, adopts the combination of the No.1 current guiding sleeves, the No.2 current guiding sleeve and the wire core sheaths, improves the anti-static performance of the cable, fully avoids the occurrence of an electrostatic phenomenon inside the cable, and utilizes the breakdown resisting layer to improve the voltage resistance of the cable, thereby prolonging the service life of the cable.

Description

A kind of antistatic superhigh pressure silicone rubber for cable

Technical field

The utility model relates to a kind of cable, specifically a kind of antistatic superhigh pressure silicone rubber for cable.

Background technology

Silicone rubber for cable is to be applicable to ac rated voltage 0.6/1KV and following fixedly laying with power transmission line or movable electrical appliances stube cable, product has the characteristics such as heat-resisting radiation, cold-resistant, acid and alkali-resistance and corrosive gas, waterproof, the construction of cable is soft, radiation is convenient, under high temperature (high and cold) environment, electric property is stable, ageing resistace is outstanding, and long service life, is widely used in the industries such as metallurgy, electric power, petrochemical industry, electronics, automobile making.And because silicone rubber for cable structural design is unreasonable, make occur in use inner static or be broken down by high-voltage that the serious normal use that has influence on instrument and equipment makes troubles to people's productive life.

Summary of the invention

It is a kind of reasonable in design, long service life, good pressure-resistant performance that technical problem to be solved in the utility model is to provide, and can prevent the cable of inner static, i.e. a kind of antistatic superhigh pressure silicone rubber for cable.

Technical problem to be solved in the utility model realizes by the following technical solutions:

An antistatic superhigh pressure silicone rubber for cable, comprises conductor and insulating barrier, and described insulating barrier is wrapped in the outer surface of conductor, and described insulating barrier is extruded with inner sheath outward; The outside of described inner sheath is enclosed with drainage sleeve No. one, and inner sheath is in order to play the effect of protection to insulating barrier and conductor; The outside of a described drainage sleeve is enclosed with core sheath; Described many core sheaths are twisted into cable core; The outside of described cable core is enclosed with screen, No. two drainage sleeves, resistance to floor and the oversheath of puncturing from the inside to the outside successively.Adopt drainage sleeve, No. two drainage sleeves and core sheath to combine, in order to cable is carried out to antistatic processing, improved the performance of cable self antistatic, avoided fully the generation of the inner electrostatic phenomenon of cable; The resistance to layer that punctures, in order to prevent the high-voltage breakdown of cable, has improved the withstand voltage properties of cable, thus the useful life of the cable extending.

The described resistance to layer that punctures is made by polyacrylonitrile fibre material, and the durability of polyacrylonitrile fibre material is higher, good pressure-resistant performance, and softness, thus improved the flexibility of cable.

Described core sheath is extruded and is formed by Process of Antistatic PAN Fiber material, can play a protective role to core so on the one hand, also cooperatively interacts with a drainage sleeve, No. two drainage sleeves on the other hand, thereby has improved the antistatic performance of cable.

A described drainage sleeve, No. two drainage sleeves respectively correspondence are provided with a tinned copper wire drainage thread, No. two tinned copper wire drainage threads, because signal code frequency and intensity are constantly to change, so the induced voltage on screen is also constantly to change, after changing, voltage will form flow of charge, a tinned copper wire drainage thread, No. two tinned copper wire drainage threads can, by the timely carrying-off of these electric charges, avoid the electric field that charge accumulated causes to concentrate.

The beneficial effects of the utility model are: the utlity model has the advantages such as reasonable in design, long service life and good pressure-resistant performance, adopt drainage sleeve, No. two drainage sleeves and core sheath to combine, improve the performance of cable self antistatic, avoided fully the generation of the inner electrostatic phenomenon of cable; Utilize the resistance to withstand voltage properties that layer has improved cable that punctures, thus the useful life of the cable extending.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is internal structure schematic diagram of the present utility model.

Embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below the utility model is further set forth.

As shown in Figure 1, a kind of antistatic superhigh pressure silicone rubber for cable, comprises conductor 9 and insulating barrier 8, and described insulating barrier 8 is wrapped in the outer surface of conductor 9, the outer inner sheath 7 that is extruded with of described insulating barrier 8; The outside of described inner sheath 7 is enclosed with drainage sleeve 6 No. one, and inner sheath 7 is in order to play the effect of protection to insulating barrier 8 and conductor 9; The outside of a described drainage sleeve 6 is enclosed with core sheath 5; Described many core sheaths 5 are twisted into cable core; The outside of described cable core is enclosed with screen 4, No. two drainage sleeves 3, resistance to floor 2 and the oversheath 1 of puncturing from the inside to the outside successively.Adopt drainage sleeve 6, No. two drainage sleeves 3 and core sheath 5 to combine, in order to cable is carried out to antistatic processing, improved the performance of cable self antistatic, avoided fully the generation of the inner electrostatic phenomenon of cable; The resistance to layer that punctures, in order to prevent the high-voltage breakdown of cable, has improved the withstand voltage properties of cable, thus the useful life of the cable extending.

The described resistance to layer 2 that punctures is made by polyacrylonitrile fibre material, and the durability of polyacrylonitrile fibre material is higher, good pressure-resistant performance, and softness, thus improved the flexibility of cable.
