Abstract
The utility model discloses a high, low temperature resistant power cable. The cable comprises a cable core arranged in the middle of the cable, and formed by a plurality of wire cores, wherein each wire core is composed of a conductor and a PET insulation layer and a PET inner jacket which are extruded on the outer part of the conductor in turn, a filler is arranged in the cable core, a steel tape armor layer is arranged outside the cable core, and an outer jacket is extruded on the outer part of the steel tape armor layer.
Description
Technical field
The utility model relates to a kind of cable, is specially a kind of high-low temperature resistant power cable.
Background technology
Cable in use, extreme low temperature can make the cable hardening, becomes fragile, be difficult to use.Especially when mounted, cable is too crisp is a very serious problem.On the other hand, high temperature may make employed plastics performance degradation in the cable.So the user should lay corresponding cable according to the temperature of expection.But existing power cable is limited for the tolerance of high and low temperature environment, can't satisfy actual needs fully.
The utility model content
The utility model purpose is the deficiency that exists for prior art, provides a kind of high and low temperature resistance good power cable.
A kind of high-low temperature resistant power cable described in the utility model, it comprises the cable core in the middle of the cable, described cable core is comprised of the several wire core, every core is by conductor and be extruded in successively the outer PET insulating barrier of conductor and the PET inner sheath forms, be provided with filler in the cable core, cable core arranges the steel-tape armouring layer outward, and the steel-tape armouring layer extrudes oversheath outward.
The beneficial effects of the utility model:
1. good mechanical property is arranged, and folding resistance is good.
2. oil resistant, anti-fat, anti-diluted acid, diluted alkaline, anti-most of solvents.
3. have good high-and low-temperature resistance performance, can be in 120 ℃ of temperature ranges use for a long time, short-term is used can anti-150 ℃ of high temperature, can anti--70 ℃ of low temperature, and very little on its mechanical performance impact during high and low temperature.
4. gas and vapor permeability are low, existing good choke, water, oil and peculiar smell performance.
5. transparency is high, but shielding of ultraviolet, and glossiness is good.
6. nontoxic, tasteless, wholesomeness is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Only be used for and be not limited only to scope of the present utility model.
As shown in Figure 1, high-low temperature resistant power cable of the present utility model, comprise the cable core that cable is middle, described cable core is comprised of the several wire core, every core is by conductor 1 and be extruded in successively conductor 1 outer PET insulating barrier 2 and PET inner sheath 3 forms, be provided with filler 4 in the cable core, cable core arranges steel-tape armouring layer 5 outward, the steel-tape armouring layer 5 outer oversheath 6 that extrudes.
Adopt PET as insulation and sheath material in the utility model, PET is milky or polymer light yellow, highly crystalline, and surface smoothing is glossy.Have good physical and mechanical properties in wider temperature range, long-term serviceability temperature can reach 120 ℃, and electrical insulating property is good, even under high-temperature high-frequency, its electrical property is still better, fatigue durability, and rub resistance, dimensional stability are all fine.
The concrete application approach of the utility model is a lot; the above only is preferred implementation of the present utility model; should be understood 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 improvement also should be considered as protection range of the present utility model.
