Abstract
The utility model relates to a double conductor heating cable, mainly comprising a heating conductor, an insulating layer, a shielding layer and an outer sheath, wherein the heating conductor is formed by at least four intertwist heating filaments, two cable cores are arranged in parallel to form a double heating conductor, the outside of the double heating conductor is wrapped with two insulating cable cores formed by polyethylene insulating layers, the outside of the two insulating cable cores is longitudinally wrapped with a plastic-aluminum composite membrane, the outside of the plastic-aluminum composite membrane is wrapped with a copper wire knitting layer, the plastic-aluminum composite layer and the copper wire knitting layer form two shielding layers, and the outside of the copper wire knitting layer is wrapped with a polyethylene sheath. Two parallelly arranged insulating cable cores form the double heating conductor, thereby being convenient for connection with an external power supply and installation construction of the cable; when knitting, the copper wire longitudinally wraps the plastic-aluminum composite membrane, thereby preventing the copper wire shielding layer from damaging the insulating cable core and playing a part in longitudinal waterproofing; and the plastic-aluminum completely covers the insulating cable core, thereby absolutely ensuring the safety of cable-using. The double conductor heating cable is simple and soft in structure and stable in electrical property and mechanical property.
Description
Technical field
The utility model relates to a kind of heating cable, particularly relate to that a kind of low temperature radiation heating system uses, be heater with electric power as the energy, heating cable, by the form of warming ground, with the warm two-conductor heating cable of sending into the room with low-temp radiating.
Background technology
Existing heating cable is distinguished from number of conductors, is divided into singly leading heating cable and two leading heating cable, and single cable inside has only a heat generating core, and cable itself does not become the loop, owing to there is electric current to pass through, can produce the inductance eddy current, produces electromagnetic radiation.The two-conductor heating cable is divided into two two heating cables and two single-shot electric heating cables of leading of leading, two pair heating cables of leading are the two-conductor heating, two-conductor single-shot electric heating cable has two conductors, wherein one is heating wire, and other one is external connection, and does not generate heat, cable end piece connects, have the loop of one's own,, have only a heating conductor though lead heating cable for two.
Existing heating cable conductor is generally single heating wire, flexibility and intensity are bad, single heating wire is when being subjected to bending, can make conductor produce crimp, the damage conductor, directly influence the useful life of heating cable, ground is flexible in addition and differential settlement of buildings etc. all can impact cable conductor.
Existing heating cable shielding aluminum foil shielded and the copper wires of adopting shield more, the installation requirement cable of heating cable has good bending property, aluminum foil shielded and copper wire all are metal material, the better mechanical property of aluminum foil shielded, but when cable is crooked, can produce extruding to cable cover(ing), the good bending property of copper wire shielding, but braid can produce extruding to the heating insulated wire cores, these two kinds of shielding constructions all can produce damage to cable, thereby influence the useful life of cable.
The heating cable that is used for indoor heating is installed on underground more; when interior decoration or other reasons cause cable fault; adopt independent copper wire shielding; can not cover insulated wire cores fully; have certain clearance between the copper wire; when tiny external metal object was not run into metal level, the copper wire shielding can not be at first charged, can not play earth leakage protective effect.
Existing two-conductor heating cable is extruded two conductors for once parallel, two conductors are easy to be sticked together in extrusion, cause short circuit, also must with two thoroughly do away with edge core with cold line (power line) when being connected at heating cable in addition and separate, increased the workload of encapsulation.
Summary of the invention
The utility model provides a kind of flexibility good at many deficiencies of prior art, and shielding is good, can effectively overcome electromagnetic radiation, and is safe in utilization, is convenient to be connected and the living facilities heating of installation and the two-conductor heating cable of anti-freeze usefulness with power line.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of two-conductor heating cable, this heating cable is mainly by heating conductor, insulating barrier, screen, oversheath is formed, described heating conductor adopts four stranded heating wires at least, per four stranded heating wires constitute the single line core, two cores are arranged in parallel and constitute two heating conductors, two heating conductors outside is enclosed with polyethylene layer respectively and forms insulated wire cores, the outside vertical bag one deck aluminum-plastic composite membrane of two insulated wire cores, and the aluminum-plastic composite membrane external packets is covered with the copper wire braid, plastic-aluminum combined rete, the copper wire braid is formed two-layer screen, the outside pe sheath that coats of copper wire braid.
Adopt technique scheme, compared with prior art, the utility model adopts 4 stranded heating conductors at least, two insulated wire cores that are arranged in parallel constitute the two-conductor heating, non-once is extruded the two-conductor insulation, shelled the jacket insulation core naturally separately, be convenient to and being connected and the installation of cable of external power supply.Vertical alclad is moulded composite membrane and is prevented the damage of copper wire screen to insulated wire cores during the copper wire braiding; vertical simultaneously alclad is moulded composite membrane and is played vertical waterproof effect; the metallic aluminium face of aluminum-plastic composite membrane closely contacts with wire sheathing; cover insulated wire cores fully; when any tiny metal object is pricked into cable; metal screen layer can be at first charged, plays earth leakage protective effect, definitely guaranteed the safe in utilization of cable.The construction of cable of two-conductor heating, aluminum-plastic composite membrane and copper wire braiding double shield has been eliminated electromagnetic radiation fully to people's the health and the influence of life.Simultaneously effectively play earth leakage protective effect, guaranteed the safe in utilization of cable.Conductor adopts the insulating material of 105 ℃ of temperature resistant grades outward, and aluminum-plastic composite membrane and copper wire braiding double layer screen are adopted in shielding, has the oversheath of 90 ℃ of temperature resistant grades outside the shielding, guarantees the useful life of cable.And adopt 4 stranded heating wire conductors and copper wire braid shielded to improve the flexibility of cable greatly, the two-conductor heating cable structure magnetic field of cancelling out each other, add the structure of aluminum-plastic composite membrane and copper wire braiding double layer screen, not only the construction of cable is simply soft, safe in utilization, electrical property, stable mechanical performance.And eliminated electromagnetic radiation fully, improved the quality of cable simultaneously.
