Abstract
The utility model provides an ultralow temperature-resistant rubber jacketed flexible cable with rated voltage of 450/750V, an isolation layer A is wrapped on a flexible copper conductor, and then the isolation layer is uniformly extruded for constituting a wire core; a plurality of wire cores are twisted into a cable core; an isolation layer B is wrapped on the outer side of the cable core; filling layers are filled in gaps among the isolation layer B and the wire cores; and a layer of outer sheath is extruded on the outer side of the isolation layer B. The insulation layers adopt ethylene-propylene rubber material with high electrical performance and resistance to low temperature of minus 70 DEG C, thus significantly improving the electrical performance and the low temperature resistance of the cable. The outer sheath adopts rubber material with resistance to low temperature of minus 70 DEG C, thus further improving the low temperature resistance of the cable. The isolation A and the isolation B adopt polyester tapes or reinforced type non-woven fabric tapes. The utility model provides the ultralow temperature-resistant rubber jacketed flexible cable with rated voltage of 450/750V, high electrical performance, high softness and resistance to the ultralow temperature of minus 70 DEG C.
Description
Technical field
The utility model relates to the anti-special low temperature rubber sleeve flexible cable of a kind of rated voltage 450/750V, belongs to technical field of electric wires and cables.
Background technology
At present, the resistance to low temperature of general Plastic-sheathed Cable can only reach-35 ℃, can not satisfy the requirement of using under the worst cold case condition more.When using under-40 ℃ of operating modes, cable is prone to sclerosis and can't normal construction, have in addition embrittlement can take place, have a strong impact on the user and under this cryogenic conditions, carry out the work.
Summary of the invention
The purpose of this utility model provides the anti-special low temperature rubber sleeve flexible cable of rated voltage 450/750V of a kind of high electrical performance, highly-flexible, ability-70 ℃ low temperature.
The technical solution of the utility model is: the anti-special low temperature rubber sleeve flexible cable of a kind of rated voltage 450/750V.It is made up of soft copper conductor, separator A, insulating barrier, packed layer, separator B and oversheath.Even again extruded insulation layer is formed core behind wrapped separator A on the soft copper conductor.Many cores are twisted into cable core.At the wrapped separator B in the cable core outside.Packed layer is filled in gap between separator B and core.Extrude one deck oversheath in the separator B outside.
Described insulating barrier adopts the ethylene-propylene rubber material of high electrical performance, ability-70 ℃ low temperature, and this material significantly improves cable electrical property and resistance to low temperature.
Described oversheath adopts the rubber material of anti--70 ℃ of low temperature.This material is further enhanced the cable resistance to low temperature.
Described separator A and separator B all adopt polyester belt or reinforced nonwoven fabric belts.
The utility model has the advantages that the anti-special low temperature rubber sleeve flexible cable of the rated voltage 450/750V that a kind of high electrical performance, highly-flexible, ability-70 ℃ special low temperature are provided.
