Description
Technical field
The utility model relates to cable technology field, provides a kind of from electric heating cable.
Background technology
When cable lays at low temperatures, will make cable impaired, when serious, will make cable bad, all will adopt different measures to heat cable during cabling at low temperatures for this reason.Existing cable can not self-heating, and the screening ability of existing cable is bad, and a little less than diamagnetic field energy power, antistatic effect is poor.
From 1836, produce in the world article one lv power cable (the wrapped copper conductor of rubber belt) so far, electric wire has developed into a large product category of many uses, various in style.China's wires and cables industry, through the development of more than 70 years, has also been obtained larger progress.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.At present the state-owned and above enterprise of scale of China's wires and cables industry is approximately 5000, and wherein large enterprise has 19, and the gross output value accounts for 11% of whole market share.
Electric wire is to carry the energy, the indispensable basic equipment of transmission of information, and from the today in social informatization, electrified fast development, electric wire has become one of most important basic product in economic construction.Wires and cables industry is again supporting industry, and product must meet each main industry requirement to electric wire performance of national economy, and national economy thinks that most industries are all relevant to electric wire, and its industrial status is very important.China's wires and cables industry is still in developing stage at present, and as the important guide's industry of the development of the national economy, the growth of electric wire production and marketing index is generally higher than total value of production in national economy outline.
Utility model content
the purpose of this utility model is to provide a kind of self heating function that has, strong a kind of from electric heating cable of strong, the antistatic interference of diamagnetic field energy power, anti-RF capabilities.
The utility model is by the following technical solutions to achieve these goals:
A kind of from electric heating cable, its spy is, comprises at least 3 conductors 4, the outer all wrap insulate layers 6 of conductor, all conductors 4 that are enclosed with insulating barrier 6 are wrapped up by internal shield 9, filler 7, inner shield 9 outer wrapping waterstops 3, waterstop 3 outer wrapping outer shielding layers 5 are filled in the gap that internal shield 9 and insulating barrier are 6, outer shielding layer 5 outer wrapping anti-corrosion asphalt layers 1, anti-corrosion asphalt layer 1 outer wrapping inner restrictive coating 2, outer wrapping inner restrictive coating 2 parcel external sheath layers 11, the interior uniform electrical heating elements 10 of inner restrictive coating 2.
Described filling filler 7 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is the strengthening course of adhering glass fiber mesh establishment respectively, and the film that bonding one deck consists of water-proofing powder on strengthening course forms water blocking layer.
Described filling filler 7 is glass fibre.
Because the utility model adopts above technical scheme, so possess following beneficial effect:
The utility model makes cable obtain higher antistatic interference, the interference of anti-external magnetic field, anti-radio frequency interference ability by inner shield and external shield.
The heater element that is provided with of the present utility model, can heat Electricity Federation.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Embodiment
The utility model relates to a kind of from electric heating cable, its spy is, comprise at least 3 conductors 4, the outer all wrap insulate layers 6 of conductor, all conductors 4 that are enclosed with insulating barrier 6 are wrapped up by internal shield 9, filler 7 is filled in the gap that internal shield 9 and insulating barrier are 6, inner shield 9 outer wrapping waterstops 3, waterstop 3 outer wrapping outer shielding layers 5, outer shielding layer 5 outer wrapping anti-corrosion asphalt layers 1, anti-corrosion asphalt layer 1 outer wrapping inner restrictive coating 2, outer wrapping inner restrictive coating 2 parcel external sheath layers 11, the interior uniform electrical heating elements 10 of inner restrictive coating 2.
Described filling filler 7 is fireproof water-resisting tape, and it comprises mica layer, and mica layer two sides is the strengthening course of adhering glass fiber mesh establishment respectively, and the film that bonding one deck consists of water-proofing powder on strengthening course forms water blocking layer.
Described filling filler 7 is glass fibre.
Electrical heating elements is that ultra-thin Nb-Al alloy steel band is made euthermic chip, ultra-thin chromium aluminium or chrome-nickel steel band.
