Abstract
The utility model relates to the field of heating equipment, and particularly relates to a double-guide heating cable. The heating cable comprises an insulator. A cavity is arranged inside the insulator. The cavity is internally provided with two heating conducting wires which are staggered, and one ground wire. The heating conducting wires are enveloped with a layer of silica gel layer. The ground wire is enveloped with a layer of PVC sheath. The insulator is enveloped with a layer of flame-retardant layer which is enveloped with a layer of heat conducting sheath layer. The heating conducting wires are staggered so that anti-bending, compression-resistant and anti-tension capacities are greatly increased. Mechanical properties of the double-guide heating cable are increased so that the service life of the double-guide heating cable is greatly increased. Besides, the double-guide heating cable is high in heating efficiency and can be widely used.
Description
Technical field
The utility model relates to a kind of heating equipment field, is specifically related to a kind of two heating cable of leading.
Background technology
Heating cable has been widely used in family, office or hotel and other occasions at present, to meet the needs of heating, traditional heating cable is divided into two kinds, and a kind of is singly to lead heating cable, and another kind is two heating cable of leading, singly lead heating cable heat generation rate low, heat energy can not be more effectively provided, and two to lead the heating cable efficiency of heating surface high, but two company's roots heating seal wires of leading in heating cable are in the past arranged in parallel, its resistance to pressure and pull resistance are poor, and failure rate is higher.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of resistance to pressure and pull resistance relatively high, two heating cable of leading that failure rate is lower.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of two heating cables of leading described in the utility model, described heating cable comprises insulator, in described insulator, be provided with cavity, two heating seal wire and earth connections that are staggered in are together installed in described cavity, described heating seal wire coenvelope one deck layer of silica gel, described earth connection coenvelope one deck PVC sheath, and described insulator coenvelope one deck flame-retardant layer, and described flame-retardant layer coenvelope one deck heat conduction restrictive coating.
Further technical scheme, described flame-retardant layer is Corvic.
Further technical scheme, described heating seal wire is Contra wire.
Adopt after said structure, the utility model beneficial effect is: the heating seal wire in the utility model is staggered in together, has greatly increased bending resistance, resistance to compression and resistance to tension, owing to having increased its mechanical property, also greatly increased its useful life, and its heating efficiency is high, can be widely used.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Description of reference numerals:
1, heating seal wire; 2, layer of silica gel; 3, earth connection; 4, PVC sheath;
5, insulator; 6, flame-retardant layer; 7, heat conduction restrictive coating.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of two heating cables of leading described in the utility model, it is characterized in that: described heating cable comprises insulator 5, in described insulator 5, be provided with cavity, two heating seal wire 1 and earth connections 3 that are staggered in are together installed in described cavity, and described heating seal wire 1 coenvelope one deck layer of silica gel 2, and described earth connection 3 coenvelopes one deck PVC sheath 4, described insulator 5 coenvelopes one deck flame-retardant layer 6, and described flame-retardant layer coenvelope one deck heat conduction restrictive coating 7.
A kind of optimal way of the present utility model, described flame-retardant layer 6 is Corvic.
A kind of optimal way of the present utility model, described heating seal wire 1 is Contra wire.
While using the utility model, the utility model beneficial effect is: the heating seal wire in the utility model is staggered in together, has greatly increased bending resistance, resistance to compression and resistance to tension, owing to having increased its mechanical property, also greatly increased its useful life, and its heating efficiency is high, can be widely used.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
