Abstract
The utility model relates to a high-temperature resistant power cable. The insulating layer of the power cable adopts a composite structure, the inner layer adopts polyfluorinated ethylene-propylene plastic with good high-temperature resistant effect, and the outer layer adopts polyvinyl chloride or butyronitrile with good mechanical properties. Compared with the prior product, the high-temperature resistant power cable provided by the utility model changes the original single-layer structure of the insulating layer into the double-layer composite structure, which can meet the requirements for being used in high-temperature occasions and enhance the mechanical properties of the cable, so that the product can be widely used.
Description
Technical field
The utility model relates to the cable technology field, particularly the employed power cable in the high-temperature field.
Background technology
The cable serviceability temperature that requires in high temperature places such as petrochemical industry, metallurgy is than higher, general polyvinyl chloride power cable can not meet the demands, and perfluoroethylene-propylene uses cracking easily in fan-shaped power cable, so use the individual layer insulation can not satisfy this two kinds of demands simultaneously.
Summary of the invention
The present invention will address the above problem, and a kind of new solution is provided.
The technical scheme that the utility model technical solution problem is adopted is:
Design feature of the present utility model is a heart yearn by the outer extruded insulation layer of conductor, and insulating barrier adopts composite construction, and internal layer adopts the effective polyfluorinated ethylene plastic of heatproof, outer polyvinyl chloride or the butyronitrile material that adopts good mechanical property.
Compare with existing product, advantage of the present invention is mainly reflected in: the present invention can satisfy the requirement in high temperature place by the insulating barrier of original single layer structure is made two-layer composite, can guarantee the quality of cable again, has widened the scope of application of product greatly.
Description of drawings
Figure one is the cable sectional structure chart, and 11 is conductor, and 12 is inner insulating layer, and 13 is external insulation layer, and 20 is lapping layer, and 31 is outer jacket.
Embodiment
The high temperature resistant power cable of the present invention comprises heart yearn; heart yearn all is to be made of conductor extruded insulation layer; insulating barrier adopts two-layer composite; inner insulating layer adopts perfluoroethylene-propylene; insulating outer layer adopts polyvinyl chloride or butyronitrile material protective layer; stranding filled high-temperature material, wrapped material glass cloth, sheath adopts polyvinyl chloride or low-smoke halogen-free polyolefin.
According to cable specification difference, when internal layer extruded insulation thickness was 0.3～2.0mm, it is best that the heat resistance of product reaches, when outer layer insulation thickness is 0.7～2.4mm, best to the protection effect of cable.
The gap has dustless mineral wool rope filler to fill around core, behind the filler rounding, at its wrapped glass fiber tape lapping layer in outside, extrudes oversheath outside lapping layer.And oxygen barrier layer and steel-tape armouring layer (expression among the figure one) also can be arranged between lapping layer and restrictive coating.
Insulating barrier in the cable of the present invention is an exotic material, and protective cover material is the low smoke and low halogen polyolefine material, has good anti-radiation property, is fit to metallurgy, electric power, petrochemical industry, heavy construction, automobile making, market and densely populated place and uses.
Claims (3)
1, high temperature resistant power cable, comprise heart yearn, lapping layer, outer jacket, wherein heart yearn extrudes the double hyer insulation layer by the conductor outside and constitutes, and it is characterized in that described insulating barrier adopts the two-layer composite of being made by internal layer polyfluorinated ethylene plastic and outer butyronitrile or pvc material.
