Abstract
The utility model relates to a dual-shield geothermal cable with double heating conductors, which sequentially comprises a sheath layer 1, an outer shield layer 2, an inner shield layer 3 and a heat transfer film 4, wherein the heat transfer film 4 comprises two heating conductors 6 which are respectively provided with an insulating layer 5, the two shield layers include the outer shield layer 2 which is a metal band and the inner shield layer 3 which is a metal braided mesh, and the sheath layer 1 and the insulating layer 5 are made of high-temperature resistant environment-friendly silicon rubber. Due to the double-conductor arrangement, magnetic fields generated by the geothermal cable can be cancelled out. Due to the double shield layers, radiation of electromagnetic wave can be shielded sufficiently, and human health can be guaranteed. The insulating layer of the geothermal cable is made of silicon rubber which has better high-temperature resistant insulating effect and is environment-friendly. Further, the sheath layer is made of PVC materials, thereby saving manufacturing cost of the cable.
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, of the present utility modelly provide 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, be followed successively by by the setting of skin: restrictive coating 1, shield external layer 2, shielding internal layer 3, heat-transfer film 4 to internal layer, comprise two heating-wires 6 in the heat-transfer film 4, insulating barrier 5 is arranged respectively on the heating-wire.
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 and insulating barrier 5 are the high temperature resistant environment-protective silastic material.
The utility model two-conductor line is provided with, and electric current is the different directions motion in lead, and cancel out each other in the magnetic field of generation, and two-layer screen is arranged, and can fully mask irradiation of electromagnetic waves, guarantees health.
Simultaneously, the cable that two-conductor line is provided with is owing to factors such as heating area are big, and its heating effect is more even.
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.
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.Restrictive coating 1 and insulating barrier 5 are the high temperature resistant environment-protective silastic material.
Heating-wire 6 can adopt the alloy silk.When use installing, at the afterbody of cable the double joint heating-wire is coupled together, form path, the electric current in the cable forms not motion in the same way, produces electromagnetism separately, and offsets mutually.
For further eliminating electromagnetic wave, two-layer cable shield is set again, shield external layer 2 can adopt metal tape, and shielding internal layer 3 can adopt metal knitted net.
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.
