Abstract
The utility model discloses a wind field-used low temperature-resistant polyethylene cable. The wind field-used low temperature-resistant polyethylene cable includes three sets of wire cores. The wind field-used low temperature-resistant polyethylene cable is characterized in that each wire core is composed of conductors as well as a conductor shielding layer, an insulating layer, an insulation shielding layer and a copper strip shielding layer which are sequentially coated on the conductors; the exterior of the three set of wire cores is wrapped with a water-resistance wrapping band; gaps outside the three sets of wire cores are filled with a filler; the exterior of the water-resistance wrapping band is provided with a water-resistance inner cushion layer; and a low temperature-resistant sheath is arranged on the outmost periphery of the cable. Compared with the prior art, and according to the wind field-used low temperature-resistant polyethylene cable of the utility model, the sheath is made of a high-density polyethylene material with excellent low temperature resistance, and at the same time, the design of a double-layer sheath structure is adopted; and therefore, the wind field-used low temperature-resistant polyethylene cable is advantageous in low temperature resistance, little possibility of cracking, and favorable water resisting property, and is more suitable for wind fields in northern cold drought areas.
Description
Technical field
The utility model belongs to cable technology field, is specifically related to the low temperature resistant Polyethylene insulated cable of a kind of wind field.
Background technology
Along with the constant tension ，Ge state of energy supply, regenerative resources green at active development all, and wind energy be free from environmental pollution, do not destroy ecology, inexhaustible, nexhaustible a kind of energy, thereby favored.Wind field area is the maximal wind-energy resource band that China joins together, and earth's surface is desert, grassland or Degraded Pastures, and most of wind field climatic characteristic is low temperature arid, and the cable matching with it must be low temperature resistant, to prevent that cable from ftractureing under low temperature environment.Due to wind field transmission, the equal directly buried installation of grid-connected cable in the wild, unavoidably have the existence of moisture, so the cable using also should have comparatively good block-water performance, existing common cable cannot meet its demand.
Utility model content
The purpose of this utility model is to provide a kind of low temperature resistant Polyethylene insulated cable of wind field of new construction, not only low temperature resistant not easy to crack, and has good block-water performance, to be suitable for northern low temperature arid area wind field, uses.
For realizing this purpose, the technical solution of the utility model is: the low temperature resistant Polyethylene insulated cable of a kind of wind field, comprise three groups of cores, described core by conductor and successively coated conductor shield, insulating barrier, insulation screen, copper strip shielding layer thereon form, the outer wrapped band that blocks water of described three groups of cores, outside described three groups of cores, in space, be filled with filler, described in the band that blocks water be provided with the inner cushion layer that blocks water outward, described low temperature resistant sheath is located at cable outermost.
As preferably, described conductor is zinc-plated stranded soft copper conductor.
As preferably, described filler is high-expansion water suction packing material.
With respect to prior art, the utility model sheath adopts the good high-density polyethylene material of resistance to low temperature, and cable does not ftracture under-35 ℃ of environment; Secondly, adopt the structural design of duplex sheath, thereby effectively stop moisture to infiltrate.Its shield effectiveness of woven shield that the annealing copper wire that is 0.2～0.4mm by diameter or tinned copper wire braiding form is better.Adopting zinc-plated stranded soft copper conductor is core conductor, and flexibility is better, contributes to extend cable life.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Wherein: 1. conductor, 2. conductor shield, 3. insulating barrier, 4. insulation screen, 5. copper strip shielding layer, 6. packing material, the band that 7. blocks water, the inner cushion layer that 8. blocks water, 9. low temperature resistant sheath.
embodiment
The utility model is further illustrated with reference to the accompanying drawings in conjunction with the embodiments.
As shown in Figure 1, the low temperature resistant Polyethylene insulated cable of a kind of wind field, comprise three groups of cores, described core by conductor and successively coated conductor shield, insulating barrier, insulation screen, copper strip shielding layer thereon form, the outer wrapped band that blocks water of described three groups of cores, outside described three groups of cores, in space, be filled with filler, described in the band that blocks water be provided with the inner cushion layer that blocks water outward, described low temperature resistant sheath is located at cable outermost.Wherein, described conductor is zinc-plated stranded soft copper conductor.Described filler is high-expansion water suction packing material.
The improvement that the utility model is undertaken by low temperature resistant Polyethylene insulated cable structure mainly for wind field, the foregoing is only the utility model preferred embodiment, non-so limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as doing by the utility model specification and graphic content, all should be contained in the scope of the claims of the present utility model.
