Abstract
The utility model relates to a geothermal cable, which is sequentially provided with the following from outside to inside: a sheathing layer 1, a shielding outer layer 2, a shielding inner layer 3, a heat transmission film 4, an insulation layer 5 and a heating lead wire 6, wherein the shielding layer adopts two layers, the shielding outer layer 2 adopts a metal strap, and the shielding inner layer 3 adopts a metal mesh grid. Besides, the sheathing layer 1 adopts high-temperature resistant and flame-retardant PVC materials, while the insulation layer 5 adopts high-temperature resistant and environment-friendly silicone rubber materials. By virtue of the two shielding layers, the geothermal cable can fully shield the radiation from electromagnetic waves, thereby ensuring health of people; moreover, the insulation layer adopts silicone rubber environment-friendly materials, thereby resulting in good high-temperature resistance and insulation.
Description
Affiliated technical field
The utility model relates to a kind of Geothermal electric cable.
Background technology
Geothermal electric cable is liked by a lot of families owing to its comfortableness.But because Geothermal electric cable is coiled in lead heating heating in the floor by it, lead is after energising, the one, can produce heat, the 2nd, generate an electromagnetic field simultaneously, if if the insulating barrier of lead can not be high temperature resistant, the heat that lead produces may burn out cable, produces very serious consequence; Electromagnetic field is harmful, live in the meeting influence very big in the electromagnetic field for a long time to people's healthy generation, though Geothermal electric cable in the market designs on electromagnetic shielding, still there is electromagenetic wave radiation to leak, still health is exerted an influence.If the insulating material of cable is all selected first-class exotic material for use, its cost will increase, and be unfavorable for saving cost, promote product.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of high temperature resistant, a kind of Geothermal electric cable that electromagnetic shielding effect is good.
The technical scheme that the utility model adopted is: it mainly is made up of heating-wire, inner insulating layer, electro-magnetic screen layer and outer protective sleeve, is followed successively by by the setting of skin to internal layer: restrictive coating 1, shield external layer 2, shielding internal layer 3, heat-transfer film 4, insulating barrier 5, heating-wire 6.Screen is two-layer, and shield external layer 2 is a metal tape, and shielding internal layer 3 is metal knitted net.Restrictive coating 1 is a heat-resistant fireproof PVC material, and insulating barrier 5 is the high temperature resistant environment-protective silastic material.
The utility model has two-layer screen, can fully mask irradiation of electromagnetic waves, guarantees health.
The utility model insulating barrier is a silastic material, and silicon rubber has the good heat-resistance insulation effect, also is a kind of environment-friendly materials simultaneously.
Because restrictive coating does not directly contact with heating-wire, therefore can adopt the pvc material simultaneously, save the cables manufacturing cost.That the pvc material has equally is fire-retardant, environmental protection, resistance to elevated temperatures.
Description of drawings
Fig. 1 is the utility model profile;
Fig. 2 is the utility model cross-sectional view.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model is followed successively by by the setting of skin to internal layer: restrictive coating 1, shield external layer 2, shielding internal layer 3, heat-transfer film 4, insulating barrier 5, heating-wire 6.Screen is two-layer, and shield external layer 2 is a metal tape, and shielding internal layer 3 is metal knitted net.Restrictive coating 1 is a heat-resistant fireproof PVC material, and insulating barrier 5 is the high temperature resistant environment-protective silastic material.
Heating-wire 6 can adopt the alloy silk.
In conjunction with the accompanying drawings embodiment of the present utility model has been carried out exemplary description above; obviously the utility model is not limited thereto, and the various remodeling that carry out in the utility model scope (comprising the extension of used material, each part dimension or shortening, the change of each point connected mode, the variation of all angles) all do not exceed protection range of the present utility model.
