Abstract
The invention discloses a self-heating anti-cracking cable. The self-heating anti-cracking cable comprises a conductor, an insulation layer, a first heat conduction layer, a heating layer, a second heat conduction layer, an outer insulation layer, a sheath and a rubber pipe; the insulation layer is extruded outside the conductor; the first heat conduction layer is extruded outside the insulation layer; the heating layer is extruded outside the first heat conduction layer; the second heat conduction layer is extruded outside the heating layer; the outer insulation layer is extruded outside the second heat conduction layer; and the sheath is extruded outside the outer insulation layer. The self-heating anti-cracking cable is simple and reasonable in structure and is anti-freezing and anti-cracking effectively.
Description
Technical field
The present invention relates to a kind of from heating anticracking cable, belong to power cable technical field.
Background technology
Electric wire is extensively applied to industrial production, communications and transportation, architectural engineering and facility, even comprise the high-end field of space and ocean, capital uses cable, along with socioeconomic development, cable kind constantly update and perfect, output is also continuing to increase, just because cable is in the application of different field, people also improve its requirement thereupon, existing cable can not meet the needs of industry because of material or structural problem, at cold district cable because low temperature causes insulating barrier to ftracture, cable is impaired, loses huge.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the invention provides a kind of from heating anticracking cable.
The solution of the present invention is as follows: a kind of from heating anticracking cable, comprise conductor, insulating barrier, heat-conducting layer one, zone of heating, heat-conducting layer two, external insulation layer, sheath and sebific duct, the outer extruded insulation layer of described conductor, the outer extruction conductive layer thermosphere one of described insulating barrier, zone of heating is extruded outside described heat-conducting layer one, the outer extruction conductive layer thermosphere two of described zone of heating, external insulation layer is extruded outside described heat-conducting layer two, sheath is extruded outside described external insulation layer, many sebific ducts are set in described sheath, be provided with quick-drying gelatin in described sebific duct, described heat-conducting layer one and heat-conducting layer two are made up of glass fibre.
Beneficial effect of the present invention: the present invention is simple and reasonable, can effective antifreeze and cracking resistance.
Accompanying drawing explanation
Fig. 1 is the structural representation of invention.
Embodiment
Below in conjunction with accompanying drawing, invention is described further.
A kind of from heating anticracking cable, comprise conductor 1, insulating barrier 2, heat-conducting layer 1, zone of heating 4, heat-conducting layer 25, external insulation layer 6, sheath 7 and sebific duct 8, the outer extruded insulation layer 2 of described conductor 1, the outer extruction conductive layer thermosphere 1 of described insulating barrier 2, zone of heating 4 is extruded outside described heat-conducting layer 1, the outer extruction conductive layer thermosphere 25 of described zone of heating 4, external insulation layer 6 is extruded outside described heat-conducting layer 25, sheath 7 is extruded outside described external insulation layer 6, in described sheath 7, many sebific ducts 8 are set, quick-drying gelatin is provided with in described sebific duct 8, described heat-conducting layer 1 and heat-conducting layer 25 are made up of glass fibre.
Although give detailed description and explanation to the specific embodiment of the present invention above; but what should indicate is; we can carry out various equivalence according to conception of the present invention to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification and accompanying drawing contain yet spiritual time, all should within protection scope of the present invention.
