Abstract
The utility model discloses a kind of oval low temperature resistant cable, described core includes conductor and oval polyamide skeleton, polyethylene foamed insulating barrier and tin plated steel wire woven shield is coated with successively in the outside of conductor, nonwoven fabrics lapping layer will be surrounded by outside after two conductor pair twists and put into described oval polyamide skeleton Inner Constitution core, flexible rod is provided with between nonwoven fabrics lapping layer and oval polyamide skeleton inwall, be placed with conductor respectively at the left and right sides of 8 described font inner sheaths and form cable core, oval double-deck zinc-plated steel-tape armouring layer is coated with successively in the outside of cable core, the heat insulation lapping layer of oval aluminium foil, oval Tarpauling lapping layer and ellipse resist cold butyronitrile oversheath.The utility model structure is simple, and use 8 font inner sheaths, warp resistance performance is good, and not easily fractureed, cost is low, effective, and resistance to low temperature is good, is applicable to various transmission line.
Description
Technical field
The utility model relates to field of cable technology, particularly relates to a kind of oval low temperature resistant cable.
Background technology
Along with the development of power industry, data communication industry, urban track traffic industry etc., the requirement of all trades and professions to cable is more and more higher, in use, not only will avoid that cable is mechanically damaged, insulation harm, ageing of insulation are rotten, also to use under cryogenic, namely low temperature resistant.Existing transmission line does not have winterized equipment, and one to winter, snows or rain easily to freeze on transmission line, breaks electric wire, causes large-area power-cuts.Sometimes even cause short circuit to cause fire, be absolutely unsafe.
Utility model content
The utility model object is exactly the defect in order to make up prior art, provides a kind of oval low temperature resistant cable.
The utility model is achieved through the following technical solutions:
A kind of oval low temperature resistant cable, include 8 font inner sheaths, core is placed with respectively in the circular space up and down of 8 font inner sheaths, described core includes conductor and oval polyamide skeleton, described conductor is twisted by the compound bundle of tin annealed copper wire and forms, polyethylene foamed insulating barrier and tin plated steel wire woven shield is coated with successively in the outside of conductor, nonwoven fabrics lapping layer will be surrounded by outside after two conductor pair twists and put into described oval polyamide skeleton Inner Constitution core, flexible rod is provided with between nonwoven fabrics lapping layer and oval polyamide skeleton inwall, be placed with conductor respectively at the left and right sides of 8 described font inner sheaths and form cable core, oval double-deck zinc-plated steel-tape armouring layer is coated with successively in the outside of cable core, the heat insulation lapping layer of oval aluminium foil, oval Tarpauling lapping layer and ellipse resist cold butyronitrile oversheath.
The utility model has the advantages that: the utility model structure is simple, and use 8 font inner sheaths, warp resistance performance is good, and not easily fractureed, cost is low, effective, and resistance to low temperature is good, be applicable to various transmission line.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of oval low temperature resistant cable, include 8 font inner sheaths 1, core is placed with respectively in the circular space up and down of 8 font inner sheaths 1, described core includes conductor 2 and oval polyamide skeleton 3, described conductor 2 is twisted by the compound bundle of tin annealed copper wire and forms, polyethylene foamed insulating barrier 4 and tin plated steel wire woven shield 5 is coated with successively in the outside of conductor 2, nonwoven fabrics lapping layer 6 will be surrounded by outside after two conductor 2 pair twists and put into described oval polyamide skeleton 3 Inner Constitution core, flexible rod 7 is provided with between nonwoven fabrics lapping layer 6 and oval polyamide skeleton 3 inwall, be placed with conductor 2 respectively at the left and right sides of 8 described font inner sheaths 1 and form cable core, oval double-deck zinc-plated steel-tape armouring layer 8 is coated with successively in the outside of cable core, the heat insulation lapping layer 9 of oval aluminium foil, oval Tarpauling lapping layer 10 and ellipse resist cold butyronitrile oversheath 11.
