Abstract
The utility model provides a compensation cable which comprises an alloy wire conductor, and an insulating layer arranged at the external side of the alloy wire conductor, wherein the surface of the insulating layer is provided with a wrapping layer, a shielding layer and an outer sheath in sequence from inside to outside, a polytetrafluoroethylene filler is arranged around the alloy wire conductor in the insulating layer. The compensation cable can resist high temperature and low temperature, has stronger adaptability and long service life, and can meet the use requirements of various places.
Description
Technical field
The utility model relates to a kind of cable, specifically compensating cable.
Background technology
The cable serviceability temperature that requires in high temperature places such as petrochemical industry, metallurgy is than higher; And it is lower in the cable serviceability temperature in-65 ℃ of environment (Arctic Circle) place.The general long-term serviceability temperature scope of polyvinyl chloride compensating cable is-20～100 ℃, can not satisfy-65～260 ℃ long-term requirements of using; The long-term serviceability temperature scope of common fluoroplastics compensating cable is-25～200 ℃, can not satisfy-65～260 ℃ long-term requirements of using.So using above cable all can not satisfy ambient temperature-65～260 a ℃ place uses for a long time.
Summary of the invention
The utility model purpose: the purpose of this utility model is the deficiency that exists at prior art, provide a kind of can either be high temperature resistant again can by chance low temperature resistant compensating cable.
Technical scheme: for achieving the above object, the technical solution adopted in the utility model is a kind of compensating cable, comprise alloy silk conductor, be arranged on the insulating barrier in the alloy silk conductor outside, be provided with lapping layer, screen and oversheath from inside to outside successively at surface of insulating layer, wherein around the inner alloy silk of insulating barrier conductor, also be provided with the polytetrafluoroethylene filler.
Described insulating barrier is the teflon insulation layer.
The film band lapping layer that described lapping layer position polytetrafluoroethylene is made.
Described screen is a nickel plating copper wire woven shield.
Described oversheath is that polytetrafluoroethylene protects oversheath.
Beneficial effect: the utility model can either be high temperature resistant again can be low temperature resistant, adaptability is strong, long service life, can satisfy the user demand in various places.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of compensating cable, comprise alloy silk conductor 1, around alloy silk conductor 1, be provided with polytetrafluoroethylene filler 3, the outside at alloy silk conductor 1 and inserts 3 is surrounded with teflon insulation layer 2, is provided with film band lapping layer 4, nickel plating copper wire woven shield 5 and polytetrafluoroethylene oversheath 6 that polytetrafluoroethylene is made from inside to outside successively on the surface of insulating barrier 2.
Insulating barrier 2 also can adopt two-layer synthetic mica tape wrapped, and it is wrapped to adopt two-layer polytetrafluoroethylene to make the film band.
This compensating cable can be used in ambient temperature for a long time and be-65～260 ℃ place, have high temperature resistant, low temperature resistant, acid and alkali-resistance, oil resistant, superior function such as anti-aging, nonflammable, have low franchise simultaneously, toward superior functions such as complex resistance are little, and be low electric capacity, low inductance, have intrinsic safety compensating cable performance, be selected to intrinsic safety thermocouple temperature measurement system.
