Abstract
The utility model discloses a kind of cold-resistant medium-pressure power cable, including cable core, described cable core is twisted by three root architecture identical insulated wire cores；The cable core is coated with external insulation layer, external shielding layer successively from inside to outside, and the hollow position of described cable core is provided with low temperature resistant urethane packed layer；Elastic caoutchouc is externally provided with external shielding layer and tightens up layer, and tightening up layer in elastic caoutchouc is externally provided with cold-resistant polyurethane lapping layer, and cold resistance polyvinyl chloride restrictive coating is externally provided with cold-resistant polyurethane lapping layer；Described insulated wire cores are formed by extruding inner insulating layer outside low temperature resistant urethane packed layer including interior low temperature resistant urethane packed layer is extruded after an anaerobic copper conductor and an aluminium alloy conductor pair twist again.The utility model is that bonding strength is high inside cable, the tensile property of cable is good, stability is good, anti-extrusion is good, cold-resistant medium-pressure power cable for a kind of insulating barrier.
Description
Technical field
It the utility model is related to field of cables, and in particular to a kind of cold-resistant medium-pressure power cable.
Background technology
Existing power cable it is more and more wider using face, the place that often pulls is needed using at some, due to insulation
Bonding strength between layer and the other structures of cable is relatively low, so insulating barrier is very easy in the case where cable pulls for a long time
Occur loosening and even come off so that the overall construction intensity of cable substantially reduces, and has had a strong impact on the normal use of cable, cable
Using effect also have a greatly reduced quality.With the more and more higher of use occasion requirement, vast in territory, temperature great disparity is larger, so
Special occasions turns into inexorable trend using cold-resistant power cable, and resist cold power cable, to solve existing for conventional common cable not
Stable, lower temperature resistance is poor, and use occasion is not wide enough, is effective method the problems such as pliability difference.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, there is provided a kind of insulating barrier connects by force inside cable
Degree is high, the tensile property of cable is good, stability is good, anti-extrusion is good, cold-resistant medium-pressure power cable.
Technical scheme：To achieve the above object, the utility model provides a kind of cold-resistant medium-pressure power cable, including cable core,
Described cable core is twisted by three root architecture identical insulated wire cores；The cable core is coated with external insulation successively from inside to outside
Layer, external shielding layer, the hollow position of described cable core are provided with low temperature resistant urethane packed layer；Elastic caoutchouc is externally provided with external shielding layer to receive
Tight layer, tightens up layer in elastic caoutchouc and is externally provided with cold-resistant polyurethane lapping layer, and cold-resistant polychlorostyrene is externally provided with cold-resistant polyurethane lapping layer
Ethene restrictive coating；Described insulated wire cores after an anaerobic copper conductor and an aluminium alloy conductor pair twist by extruding interior low temperature resistant ammonia
Ester packed layer extrudes inner insulating layer outside low temperature resistant urethane packed layer inside again and formed.
Further, described elastic caoutchouc tightens up layer and is provided with multiple elastic extruded holes.
Beneficial effect：Compared with prior art, the utility model tightens up layer using rubber can be to shielding for the utility model
Layer applies inside tightening force, so as to further improve stability of the screen layer inside cable；Overall structure is simple, filling
Layer, lapping layer, jacket portions use cold-resistant material, effectively improve every cold tolerance, more more stable than common cable cold tolerance
Property, anticorrosive property is more preferable, and creep-resistant property is more preferable, and pliability is stronger, using anaerobic copper conductor and aluminium alloy conductor pair twist structure,
Properties are effectively improved, more more stable than fine copper, fine aluminium cable, electrical conductivity is higher, and this product service life length, meeting actually makes
With requiring.Elastic caoutchouc tightens up layer and is provided with multiple elastic extruded holes, can greatly increase cable to epipolar restriction, will not make
Obtain distortion of the cable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after the utility model has been read, art technology
Modification of the personnel to the various equivalent form of values of the present utility model falls within the application appended claims limited range.
As shown in figure 1, the utility model provides a kind of cold-resistant medium-pressure power cable, including cable core, described cable core is by three
Root architecture identical insulated wire cores are twisted；, the hollow position of described cable core is provided with low temperature resistant urethane packed layer 5；The cable
Core is coated with external insulation layer 6, external shielding layer 7 successively from inside to outside；Elastic caoutchouc is externally provided with external shielding layer and tightens up layer 8, in bullet
Property rubber tightens up layer and is externally provided with cold-resistant polyurethane lapping layer 9, and cold resistance polyvinyl chloride sheath is externally provided with cold-resistant polyurethane lapping layer
Layer 10；Described insulated wire cores are filled out by extruding interior low temperature resistant urethane after an anaerobic copper conductor 1 and a pair twist of aluminium alloy conductor 2
Inner insulating layer 4 is extruded including filling layer 3 again outside low temperature resistant urethane packed layer to form；
Described elastic caoutchouc tightens up layer and is provided with multiple elastic extruded holes 11, can greatly increase the external extruding of cable
Power, distortion of the cable will not make it that.
General principle, principal character and advantage of the present utility model has been shown and described above.The technical staff of the industry
It should be appreciated that the utility model is not restricted to the described embodiments, the simply explanation described in above-described embodiment and specification is originally
The principle of utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model also has various change
And improvement, these changes and improvements are both fallen within claimed the scope of the utility model.
