Abstract
The invention discloses a low-temperature rubber-jacketed flexible cable, consisting of a flexible copper conductor, an isolating layer A, an insulating layer, a filling layer, an isolating layer B and an external jacket. The flexible copper conductor is wrapped with the isolating layer A and then is uniformly extruded with the insulating layer to form a wire core. A plurality of the wire cores are twisted to form a cable core. The insulating layer B is wrapped outside the cable core. The filling layer is filled at a gap between the isolating layer B and the wire core. The external jacket is extruded outside the isolating layer B. The invention provides an ultra-low temperature resistant rubber-jacketed flexible cable which has the advantages of high electrical property, high flexibility, capability of resisting the ultra-low temperature of 70 DEG C below zero and rated voltage of 450/750V, and meets the usage requirements under the lower-temperature working condition.
Description
Technical field
The present invention relates to technical field of electric wires and cables, particularly the rubber sleeve flexible cable technical field is specially a kind of low temperature rubber sleeve flexible cable.
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 occur, have a strong impact on the user and under this cryogenic conditions, carry out the work.
Summary of the invention
The anti-special low temperature rubber sleeve flexible cable of rated voltage 450/750V that the purpose of this invention is to provide a kind of high electrical performance, highly-flexible, ability-70 ℃ low temperature.
Technical scheme of the present invention is: a kind of low temperature rubber sleeve flexible cable is comprised of soft copper conductor, separator A, insulating barrier, packed layer, separator B and oversheath.Even extruded insulation layer forms core again 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 non-woven fabrics band.
Advantage of the present invention has provided 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 ℃ special low temperature, the requirement of using under the satisfied more worst cold case condition.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of structural representation of low temperature rubber sleeve flexible cable.
Among the figure: 1, soft copper conductor; 2, separator A; 3, insulating barrier; 4, core; 5, packed layer; 6, cable core; 7, separator B; 8, oversheath.
Embodiment
Embodiment shown in Figure 1 is as follows: wrapped one deck polyester belt isolation layer A 2 on the surface of soft copper conductor 1.The ethylene-propylene rubber insulated with material layer 3 that evenly extrudes one deck high electrical performance, ability-70 ℃ low temperature on separator A 2 consists of core 4.Three cores 4 are twisted into cable core 6.At cable core 6 outside wrapping bag reinforced nonwoven fabric belts separator B 7.Packed layer 5 is filled in gap between separator B 7 and each core 4.Extrude the rubber material oversheath 8 of anti--70 ℃ of low temperature of one deck in separator B 7 outsides.
