Compared with the prior art, the utility model, leave the flute layer between restrictive coating and shielding layer, form the mobile cavity of air, be favorable to even the distributing to the external world of heat. The utility model has the characteristics of high temperature resistant, the heat dissipation is even, no electromagnetic radiation, heat aging resistance and long service life.
Description
Technical field
The utility model belongs to field of cable technology, is specifically related to a kind of Geothermal electric cable.
Background technology
Along with the high speed development of national economy; the requirement of Environmental protection is more and more higher; the requirement of traditional heating service device improper current era development; Geothermal electric cable due under its noiselessness, smoke dust, the temperature difference, conserve space, without waste gas, the advantage such as non-maintaining, applied widely, like by vast family.
But Geothermal electric cable quality is on the market uneven, insulation grade anti-corrosion is inadequate, and conductor may burn out cable when generation heat, causes the loss of personnel's property; Geothermal electric cable generates an electromagnetic field, and contact electromagnetism can cause serious healthy hidden danger to the health of people for a long time.
Summary of the invention
According to above the deficiencies in the prior art, the utility model proposes a kind of Geothermal electric cable, to reach the uniform object of cable dissipate heat.
To achieve these goals, the technical scheme that the utility model is taked is:
A kind of Geothermal electric cable, comprises conductor and is located at the insulating barrier outside conductor, and the outer jacket also comprise wrapped separator outside insulating barrier, being located at the screen outside separator and being located at outside screen, is provided with corrugated layer between described screen and outer jacket.
Preferably, described corrugated layer is semicircle corrugated layer.
Preferably, described conductor is Manic skein silk compound.
Preferably, the material of described insulating barrier is heat resistant silicon rubber insulation material.
Preferably, the material of described corrugated layer is heat transfer heat-resistant polyvinyl chloride.
Preferably, described outer jacket is heat transfer heat resistant plastice.
Preferably, described screen is shielding layer of copper wires.
The utility model beneficial effect is: the utility model compared with prior art, leaves corrugated layer between restrictive coating and screen, forms air flow cavity, is conducive to outwardly distributing of even heat; Conductor adopts that B alloy wire is stranded forms, and monofilament specification is little, reduces the diameter of cable from conductor, and this conductor temp .-elevating efficiency is high, can be absolutely heat energy electric energy conversion, can not cause waste when power conversion; Screen adopts proof copper-wire braided to form, and has good effectiveness; Insulating barrier adopts heat-resistant silicon rubber, under normal serviceability temperature, can cross and ensure that its material itself can not cause aging, thus ensure that useful life; Restrictive coating adopts heat transfer heat resistant plastice, and its heat radiation evenly, effectively can reduce the local deformation that high temperature causes.
Accompanying drawing explanation
Below the content expressed by this Figure of description and the mark in figure are briefly described:
Fig. 1 is the structural representation of thermal-insulating type Geothermal electric cable of the present utility model.
In figure 1, conductor, 2, insulating barrier, 3, separator, 4, screen, 5, corrugated layer, 6, outer jacket.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help, those skilled in the art conceive utility model of the present utility model, technical scheme has more complete, accurate and deep understanding.
A kind of Geothermal electric cable, as shown in Figure 1, comprise conductor 1 and be located at the insulating barrier 2 outside conductor, the outer jacket 6 also comprise wrapped separator 3 outside insulating barrier, being located at the screen 4 outside separator and being located at outside screen, is provided with corrugated layer 5 between described screen 4 and outer jacket 6.Conductor 1 adopts the stranded B alloy wire conductor of Manic; Monofilament specification is little, reduces the diameter of cable from conductor, and this conductor temp .-elevating efficiency is high, can be absolutely heat energy electric energy conversion, can not cause waste when power conversion.
Preferably, corrugated layer 5 adopts heat transfer heat-resistant polyvinyl chloride to extrude and forms, and described corrugated layer is semicircle corrugated layer.Between screen and outer jacket, leave air flow cavity, be conducive to outwardly distributing of even heat.
Preferably, described insulating barrier 2 forms for heat resistant silicon rubber insulation material extrudes.This heat resistant silicon rubber insulation layer extrudes and form insulated wire cores outside conductor 1.Heat resistant silicon rubber insulation material operating temperature range is large, forever can use at 150 DEG C, without performance change, at 200 DEG C, can use 10000h continuously, also have lower temperature resistance, subzero 50 DEG C time, still elasticity is good, and uvioresistant, ozone and chemical attack, thermal stress excellent performance, adaptive temperature mechanical periodicity, and electrical insulation capability is good.Under normal serviceability temperature, can cross and ensure that its material itself can not cause aging, thus ensure that useful life.
Preferably, separator 3 adopts polyester belt, and it has higher mechanical strength, remarkable insulation property, high temperature resistant, low temperature resistant, is desirable wrapped material.
Preferably, described screen 4 is shielding layer of copper wires.There is good effectiveness.
Preferably, described outer jacket 6 is heat transfer heat resistant plastice.Heat resistant plastice main component comprises basis material and filler.Basis material comprises PPS, PA6/PA66, LCP, TPE, PC, PP, PPA, PEEK etc.; Filler comprises AlN, SiC, Al2O3, graphite, fibrous highly-conductive hot carbon powder, flakey highly-conductive hot carbon powder etc.Its product performance, heat radiation evenly, avoids scorching hot point, reduces the local deformation that Yin Gaowen causes.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection range of the present utility model without to improve.The protection range that protection range of the present utility model should limit with claims is as the criterion.
