Abstract
The utility model discloses a pressure-reducing anti-interference power cable composed of a fluororubber sheath, a tinned copper wire braiding shielding layer, a damping layer, a silicone rubber insulating layer, a main cable core and a thermoplastic rubber separating layer. The damping layer is arranged inside the tinned copper wire braiding shielding layer in an extruding manner, and the outside of the tinned copper wire braiding shielding layer is wrapped with the fluororubber sheath. The main cable core comprises an annular conductor and a drainage wire, the conductor and the drainage wire are concentrically fixed by the thermoplastic rubber separating layer, and the main cable core is arranged inside the silicone rubber insulating layer in an extruding manner. The pressure-reducing anti-interference power cable is applicable to power cables laid underground, and is characterized by light weight, corrosion resistance, excellent pressure-reducing effect, excellent anti-interference performance and good heat dissipation performance.
Description
Technical field
The utility model relates to field of cables, relates in particular to the anti-interference power cable of a kind of decompression.
Background technology
At present, phase conductor, overhead ground wire and the power cable of optical cable and power transmission line are complex as a whole to structure, be optical cable, this structure has ground wire and the dual-use function of communicating by letter concurrently, and power department is for improving the security reliability of optical cable transmission circuit, preferably electric power special optical cable is laid along high-voltage line power line, but common cable can not be tackled heavy burden pressure, easily cause conductors against damage and poor anti-interference, heat radiation row is bad, main cause be the design of cable do not in place.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide the anti-interference power cable of a kind of decompression.
The utility model takes following technical scheme to realize: the anti-interference power cable of a kind of decompression, by fluorubber sheath, tinned copper wire woven shield, buffer layer, silicone rubber insulation layer, master core and thermoplastic elastomer separator, formed, described tinned copper wire woven shield inside is extruded with buffer layer, and coated outside has fluorubber sheath; Described master core comprises conductor and drainage thread, and described conductor is annular, and described thermoplastic elastomer separator is fixing with one heart by conductor and drainage thread; In described silicone rubber insulation layer, be extruded with master core.
Described buffer layer adopts foam rubbery material.
Described conductor adopts stranded the forming of multiply tinned copper wire.
The utlity model has in sum following beneficial effect: this cable is applicable to spread the power cable into underground, have lightweight, corrosion-resistantly, depressurization and interference free performance are excellent, the feature that thermal diffusivity is good.
Accompanying drawing explanation
Fig. 1 is the utility model cross-sectional structure schematic diagram;
Wherein: 1, fluorubber sheath; 2, tinned copper wire woven shield; 3, buffer layer; 4, silicone rubber insulation layer; 5, conductor; 6, drainage thread; 7, thermoplastic elastomer separator.
Embodiment
As shown in Figure 1, the anti-interference power cable of a kind of decompression, fluorubber sheath 1, tinned copper wire woven shield 2, buffer layer 3, silicone rubber insulation layer 4 and master core, consist of, described tinned copper wire woven shield 2 inside are extruded with buffer layer 3, and coated outside has fluorubber sheath 1; Described master core comprises conductor 5 and drainage thread 6, and described conductor 5 is annular, and described thermoplastic elastomer separator 7 is fixing with one heart by conductor 5 and drainage thread 6; In described silicone rubber insulation layer 4, be extruded with master core.
Described buffer layer 3 adopts foam rubbery material.
Described conductor 5 adopts stranded the forming of multiply tinned copper wire.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the fluorubber oversheath 1 in the utility model has very high electrical insulating property, high temperature resistant, oil resistant, wear-resisting, resistance to tear-proof, resistance to oxidation and chemical-resistant stability;
2, buffer layer 3 adopts foam rubbery material, when cable pressurized, has the effect of releasing the pressure, and avoids the conductor in cable to cause damage;
3, arranging of drainage thread 7 can effectively be reduced the interference of static to signal, superior electrical property;
4, conductor 5 is arranged to annular, is conducive to heat radiation, slows down the aging speed of cable, and the life-span is longer.
The above is the utility model embodiment, and the equivalence of doing according to structure, feature and principle described in the utility model application range therefore all changes or modifies, and is included in the utility model patent claim.
