Abstract
The utility model discloses a double-conductor heating cable, comprising even number of heating conductors with surface wrapped with an insulating layer, a heat conduction sheath layer, a metal shielding layer and a grounding current discharging line, wherein the grounding current discharging line and the heating conductors are all embedded in the shielding layer, the sheath layer wraps up the shielding layer and the two adjacent heating conductors are provided with currents therein with opposite transmission directions. The double-conductor heating cable has excellent mechanical properties comprising high tensile strength and good bendability, high heating efficiency, long service life and stable work performance, can be widely used in a plurality of places such as life, work and leisure place.
Description
Technical field
The utility model relates to a kind of heating cable, relates in particular to a kind of structure improved heating cable of singly leading that has.
Background technology
Heating cable has been widely used in family, office or hotels and other places at present, to satisfy the needs of heating.Yet existing heating cable ubiquity is prone to aging, and useful life is short, bad mechanical strength, and therefore many deficiencies such as heating efficiency is low need periodic inspection to safeguard in practical application, waste time and energy, but also possibly cause serious potential safety hazard.
The utility model content
The purpose of the utility model is to provide a kind of have good mechanical strength and heating efficiency, and the two of long service life lead heating cable, thereby have overcome deficiency of the prior art.
For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme:
A kind of two heating cable of leading; It is characterized in that: it comprises that even number root surface is coated with the heating conductor of insulating barrier, a heat conduction restrictive coating, a metal screen layer and an electric drainage by grounding line; Said electric drainage by grounding line and heating conductor all are embedded in the screen; Said restrictive coating is coated on the screen, and is connected with the opposite electric current of transmission direction in adjacent two heating conductors.
Preferably, said heating cable comprises two heating conductors, is connected with equal and opposite in direction in these two heating conductors, but the opposite electric current of transmission direction.
Said heating conductor is to be closed by a plural number strand heating alloy skein silk to form.
The tinned copper wire that said electric drainage by grounding line is 0.4mm by 8 diameters is formed.
Compared with prior art; The utility model has following advantage at least: have the excellent mechanical property that comprises high-tensile and good bending property, heating efficiency is high, long service life; Stable work in work can be widely used in multiple places such as life, work, leisure.
Description of drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment.
Embodiment
Below a joint accompanying drawing and a preferred embodiment are further described the technical scheme of the utility model.
Consult Fig. 1; This pair led heating cable and comprises that two surfaces are coated with the heating conductor 13 of insulating barrier 14, a heat conduction restrictive coating 11, a metal screen layer 12 and an electric drainage by grounding line 15; This electric drainage by grounding line and heating conductor all are embedded in the screen; This restrictive coating is coated on the screen, and is connected with equal and opposite in direction in these two heating conductors, but the opposite electric current of transmission direction.
Aforementioned heating conductor preferably adopts the multiply copper alloy skein silk of resistance consistency, good stability to close conductor; It is stable, even that it has heating, good bending property, and have very high-tensile; In indeformable, not atrophy below 280 ℃; Especially for the small dimension conductor, can adopt very high-tensile reinforced wire, to avoid problem because of the too small easy fault of hot and cold joint that causes in line footpath.
The aforementioned dielectric layer preferably adopts environmental protection, nontoxic, nuisanceless; High temperature resistant; Density is little, Heat stability is good; The crosslinked polyethylene that ageing properties is superior.
The tinned copper wire that aforementioned electric drainage by grounding line is 0.4mm by 8 diameters is preferably formed.The sectional area of 8 tinned copper wires is 1.0048mm
2, the earth connection that meets IEC60800 and GB/T20841-2007 regulation must not be less than 1mm
2Regulation.
The aforementioned metal screen can make it and can not by earth connection electromagnetic field be introduced the earth again to outdiffusion being controlled at electromagnetic field in the heating cable cable core, makes cable and the earth form equipotential.
Aforementioned oversheath preferably adopts 105 ℃ of degree PVC, and it has good heatproof, anticorrosion, acid and alkali-resistance, anti-aging effect.
Need to prove; The utility model can also have other numerous embodiments; But under the situation that does not deviate from utility model spirit and essence thereof; Those skilled in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
Claims (4)
1. lead heating cable for one kind pair; It is characterized in that: it comprises that even number root surface is coated with the heating conductor of insulating barrier, a heat conduction restrictive coating, a metal screen layer and an electric drainage by grounding line; Said electric drainage by grounding line and heating conductor all are embedded in the screen; Said restrictive coating is coated on the screen, and is connected with the opposite electric current of transmission direction in adjacent two heating conductors.
2. lead heating cable for as claimed in claim 1 pair, it is characterized in that: said heating cable comprises two heating conductors, is connected with equal and opposite in direction in these two heating conductors, but the opposite electric current of transmission direction.
