In the utility model technique scheme, metallic sheath has been replaced original organic sheath, makes original accompanying-heat cable mechanical strength shortcoming low, the effectiveness difference be readily solved.Be the good conductor of heat simultaneously owing to metal, so heat-conducting effect is also very desirable.
As preferably, described metallic sheath is copper sheath, stainless steel sheath or high temperature alloy sheath; Described heating core material is copper, cupromanganese, corronil or nichrome; The material of described organic insulator is a kind of in polyvinyl chloride, ethylene-propylene rubber, silicon rubber, crosslinked polyethylene, ethene or the vinyl acetate.
As preferably, in the time of 20 ℃ ± 1 ℃, the resistance value maximum deviation of heating core is-5% and+10%; In the time of 20 ℃ ± 5 ℃, the puncture voltage 〉=2.0kV of described heat tracing cable with organic insulated metal sheath, in the time of 100 ℃ ± 3 ℃, the puncture voltage 〉=1.5kV of described heat tracing cable with organic insulated metal sheath; In the time of 100 ℃ ± 3 ℃, the resistance of the organic insulator of described heat tracing cable with organic insulated metal sheath is at least 0.03M Ω km; The thickness of described organic insulator is 0.9mm～1.1mm, and the thickness of metallic sheath is 0.45mm～0.55mm; The highest permission working temperature of described heat tracing cable with organic insulated metal sheath is 80 ℃.
It is not an easy thing that organic sheath is replaced with metallic sheath, and at first sheath is the absolute insulating properties that metal then must guarantee insulating barrier, otherwise is easy to occur accident because metal is electric good conductor.Secondly, physical attribute aspects such as the hardness of metal and organic material, pliability all differ widely, and can not use original technology to make, and must research and develop the technology that makes new advances; And the unsteadiness of the product that new technology is brought is unpredictable, must make the technical indicator of strict process requirement and product by test repeatedly; Be reflected at the complexity of being not only manufacture method in the production but also be higher technical difficulty; What be reflected on the product to be brought then is the quality of stable homogeneous.
In sum, the utlity model has following beneficial effect:
1, the utility model cable has mechanical strength height, earth resistance is low, heat conduction is even, effectiveness is good advantage, simultaneously, so because oversheath is that metallic sheath organic insulator and air are isolated fully, the useful life of having improved cable greatly;
2, the utility model not only can be used for flooring heating such as dwelling house, office building, hotel, cinema, also can be used for pipeline tracing insulation, antifreeze, the melting ice and snow in roof, road, ramp etc., brooder electric heating, fields such as lawn maintenance.
