Description
Technical field
The utility model relates to heating cable technical field, particularly a kind of novel two heating cables of leading.
Background technology
Heating cable is the most ripe, reliable, safe product in current electric floor heating heater element. At present, on market, common heating cable comprises and singly leads heating cable and two heating cables of leading. Wherein, singly lead heating cable simple in structure, cost is low, but exist, trouble, shortcoming that efficiency of construction is low is installed, and in cost of labor more and more higher today, its shortcoming is also more and more outstanding, therefore, is substituted gradually by two heating cables of leading.
But, existing two heating cable following problems of ubiquity in the process using of leading: 1, only have single line heating in cable, generate heat inhomogeneous; And between two insulated wires, how filling all can be gapped, also can be gapped in the middle of packing material, this will make heat conduction and the thermal diffusivity of whole cable bad, and when work, the temperature of cable self is higher, thereby affects security reliability and the service life of cable. 2, cable shield is poor, and electromagnetic radiation is serious, and this also will greatly affect security reliability and the service life of heating cable. 3, existingly two lead the line with heating function of heating cable and the insulation of power line is extruded at twice, also needing of having increases by a step twisted synthesizing cable operation, in production process, can insulating barrier be had and be stretched and the impact of extruding, makes production efficiency and reliability all lower. , and be necessary to develop novel two heating cables of leading therefore.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of safe and reliable, long service life, the novel two heating cables of leading that easy for installation and production cost is low are provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of novel two heating cables of leading, it comprises even number root heating conductor, heating conductor is enclosed with insulating barrier, aluminium foil layer, tinned wird netting layer and restrictive coating outward successively, insulating barrier outside the described even number root heating conductor insulating barrier that is formed in one, one-body molded insulating barrier entirety is wrapped in the outside of all heating conductors.
Preferably, described one-body molded insulating barrier is figure of eight integral insulation layer, and described one-body molded insulating barrier is wrapped in the outside of all heating conductors by extrusion modling entirety.
Preferably, the quantity of described heating conductor is two, and two heating conductors have identical resistivity. Can be by accurately manufacturing and designing heating conductor material, physical dimension when concrete use, make the linear fever power of single heating conductor only have the half of single-shot electric heating cable, thereby the heating linear power that ensures whole cable is constant, make whole cable heating evenly.
Preferably, described insulating barrier is temperature-resistant insulation layer. When heating conductor and insulating barrier are at high temperature worked, all can there is not oxide etch and aging phenomenon, security reliability and the service life of greatly improving cable.
Preferably, described heating conductor is by 6 ~ 8 stranded forming of heating wire.
Preferably, described restrictive coating is PVC sleeve pipe.
Preferably, described restrictive coating outer surface is wave structure. Wave structure can increase the area of dissipation of restrictive coating, improves heat dispersion.
The utlity model has following advantage:
1, two conductors in cable are heater, and heating evenly. Can be by accurately manufacturing and designing heating conductor material, physical dimension when concrete use, make the linear fever power of single heating conductor only have the half of single-shot electric heating cable, thereby the heating linear power that ensures whole cable is constant, make whole cable heating evenly.
2, the insulating barrier of two heating conductors is Integratively formed, has improved reliability and the production efficiency of cable. The heating conductor in the utility model, two bundles having been twisted adopts Integratively insulation moulding, and such insulated wire is being made after cable, and the insulating barrier of two heating conductors can closely be combined into an entirety, very close to each other each other; And two aluminium foil layer, tinned wird netting layer and the restrictive coatings that thoroughly do away with edge heating conductor and outside also can closely be combined into an entirety; Thereby can greatly improve heat conduction and the heat dispersion of cable, the heat energy in time heating conductor being produced distributes in the mode of conduction, ensures that cable is operated under lower state of temperature. And insulating barrier adopts an extrusion modling, and production efficiency improves greatly.
3, adopt the vertical Bao Bingyong tinned copper wire braid shielded of aluminium foil, can solve well electromagnetic radiation: the vertical bag of the additional aluminium foil of insulating barrier, aluminium foil forms a complete cavity conductor, can isolate the impact of inside and outside electrostatic field after ground connection; Additional one deck tinned copper wire netting layer after the vertical bag of aluminium foil, because tinned copper wire is very anti-oxidant, can ensure the long-time better ground connection of cable shield. What can well cable be produced in the time working by above structure is electromagnetic-field-shielded in cable, avoids to external radiation, thereby ensures the security using.
4, easy for installation, efficiency is high. Lead heating cable for this pair and can have loop of one's own, power input is only one end, and the other end is short circuit. When mounting and installation, only need power input to penetrate electric source connecting box wiring, and other end fixed installation on the spot after can completing with cable laying, do not need wraparound electric source connecting box place again, install very convenient, thereby greatly improved installation effectiveness, reduced construction cost, be conducive to apply.
