Abstract

The utility model provides a kind of heating insulated cable, it includes heating wire and the insulation system, aluminium-plastic tape and the fire retardant jacket that are coated on successively from inside to outside on the outside of the heating wire, and is also further folded with electro-magnetic screen layer between the aluminium-plastic tape and the fire retardant jacket.It is described in the utility model heating insulated cable can effectively produced by shield heating insulated cable electromagnetic radiation, the electromagnetic radiation harm healthy for electronic equipment and people is preferably minimized；Secondly, described heating insulated cable eliminates many ground wires in tradition heating insulated cable, and by the electro-magnetic screen layer while being grounded function, simple structure manufactures also more simple, final product quality is also higher on the basis of shielding electromagnetic radiation is played.

Description

One kind heating insulated cable

Technical field

The utility model is related to field of cables, more particularly to a kind of for family, unit, school, market, public place of entertainment etc. The heating insulated cable of the electric heating in all kinds of Architecture Fields.

Background technology

In addition to being heated using traditional heating, people are also increasingly employed electricity and adopt conventional heating mode at present Warm mode, is at this moment accomplished by using heating insulated cable in finishing.And with the temperature of the heating wire in the insulated cable that generates heat During gradually rising, its is inevasible to produce a certain degree of electromagnetic radiation, when the intensity of electromagnetic radiation reaches one Regularly, it not only can bring interference to each electronic equipment for being used in building place, make it cannot normal work, it is also possible to Influence can be produced on the personnel in the electromagnetic radiation environment, can more influence that people's is healthy when serious, for example, influence The vision system of people, cardiovascular system, reproductive system, What is more can induce the diseases such as leukaemia, malignant tumour.

On the other hand, the heating insulated cable for being used at present, is that many ground connection are wrapped up on the inside of the aluminium-plastic tape Line, and the function that the heating insulated cable is grounded is completed by such ground wire, its structure is relative complex, and in actual system During making, the position of many ground wires is also not susceptible to fix, and such structure can not only influence the heating insulated electro The production efficiency of cable, can also influence the quality of produced heating insulated cable, cause quality problems in use.

Utility model content

The utility model is directed to a kind of heating insulated cable that can effectively shield electromagnetic radiation.

In order to achieve the above object, the utility model provides following technical scheme：

Heating insulated cable described in the utility model includes heating wire and is coated on the heating successively from inside to outside Insulation system, aluminium-plastic tape and fire retardant jacket on the outside of silk, and between the aluminium-plastic tape and the fire retardant jacket Also further it is folded with electro-magnetic screen layer.

Further, the electro-magnetic screen layer is the longitudinally wrapped proof copper-wire braided shielding on the outside of the aluminium-plastic tape Layer.

Further, a silastic-layer is provided between the heating wire and insulation system.

Further, the thickness of the silastic-layer is between 1mm~3mm.

Further, the insulation system is organosilane crosslinked polyethylene layer, and the thickness of the organosilane crosslinked polyethylene layer exists Between 0.5~1.5mm.

Further, the fire retardant jacket is pvc sheath or flame-retardant low-smoke halogen-free polyolefin sheath layer.

Heating insulated cable described in the utility model, its sandwiched between the aluminium-plastic tape and the fire retardant jacket There is an electro-magnetic screen layer, the electromagnetic radiation that the set electro-magnetic screen layer can effectively produced by shield heating insulated cable, The degree of electromagnetic radiation pollution is effectively lowered, to control within the acceptable range, so that by electromagnetic radiation for electricity Sub- equipment and the healthy harm of people are preferably minimized.

Secondly, heating insulated cable described in the utility model eliminates many ground connection in tradition heating insulated cable Line, and by the electro-magnetic screen layer while being grounded function, simple structure is manufactured on the basis of shielding electromagnetic radiation is played Also more simple, final product quality is also higher.

Specific embodiment

Heating insulated cable described in the utility model is illustrated below in conjunction with the accompanying drawings.

Heating insulated cable described in the utility model includes heating wire 1 and is coated on the heating successively from inside to outside Insulation system 2, aluminium-plastic tape 3 and fire retardant jacket 4 on the outside of silk 1, and in the aluminium-plastic tape 3 and the fire retardant jacket Proof copper-wire braided screen layer 6 is also further folded between 4.And one of the present utility model preferred embodiment in, institute State proof copper-wire braided screen layer 6 and may alternatively be other electromagnetic shielding Rotating fields with electro-magnetic screen function anyly.It is described Proof copper-wire braided screen layer 6 is coated between the aluminium-plastic tape 3 and the fire retardant jacket 4 in longitudinally wrapped mode.

Preferably, the insulation system 2 is organosilane crosslinked polyethylene layer, and the thickness of the organosilane crosslinked polyethylene layer exists Between 0.5~1.5mm.

The fire retardant jacket 4 is pvc sheath or flame-retardant low-smoke halogen-free polyolefin sheath layer.

Further, in order to increase it is described heating insulated cable flexibility, make its heating when be difficult bending place produce Open circuit, the utility model as shown in Figure 1 preferred embodiment in, the heating insulated cable includes heating wire 1 And it is coated on insulation system 2, aluminium-plastic tape 3 and the fire retardant jacket 4 in the outside of the heating wire 1 successively from inside to outside, and Proof copper-wire braided screen layer 6 is also further folded between the aluminium-plastic tape 3 and the fire retardant jacket 4, and described A silastic-layer 5 is provided between heating wire 1 and insulation system 2.

One of the present utility model preferred embodiment in, the thickness of the silastic-layer 5 is between 1mm~3mm.

Although depicting the utility model by embodiment herein, it will be appreciated by the skilled addressee that not departing from It is of the present utility model in the case of spirit of the present utility model and essence, so that it may the utility model is had many deformations and change Scope is limited to the appended claims.
