Abstract
The utility model provides a metal full shielding double conductor heating cable. The metal full shielding double conductor heating cable comprises heating conductors and an insulating layer wrapping the outside of the heating conductors. The outside of the insulating layer is wrapped with a metal shielding layer. A grounding wire is arranged between the insulating layer and the metal shielding layer. No hole is between inner and outer walls of the metal shielding layer. The outside of the metal shielding layer is wrapped with an outer sheath. The metal full shielding double conductor heating cable provided by the utility model has the advantages of high mechanical strength and small electromagnetic radiation, solves the problems of swelling and bad contact, which are caused by hot and cold alternating, ensures smooth welding transition of a cable cold lead and a heating wire, has good anti-aging property, mechanical property and environment-resisting property, and has an excellent electrical property and a good operation safety property.
Description
Technical field
The utility model relates to the two heating cable of leading of a kind of metal full-shield.
Background technology
Traditional heating cable is shielding or the shielding of employing woven wire not, and electromagnetic radiation is larger, does not allow to be used in dwelling house life heating.Traditional heating cable joint adopts the circumscribed cold junction, because technology and technique are incomplete, heating part and the power supply lead wire of heating cable can only be processed respectively, then adopt the mode of cold junction to connect, not only production process is loaded down with trivial details, and waterproof, tension, compressive property are relatively poor, and failure rate is higher.Traditional heating cable insulating material adopts PVC, the insulating exruded rear outer protective sleeve that directly squeezes, and its pull resistance is relatively poor, and resistance to pressure is poor, and adstante febre punctures easily, and failure rate is high.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of metal full-shield two heating cable of leading, mechanical strength is high, electromagnetic radiation is little, the expansion and the loose contact that cold and heat succeed each other and bring have been solved, can guarantee cable cold pin, the level and smooth welding transition of heating wire, ageing-resistant performance, mechanical performance and anti-environment functional has excellent electric property and good operational safety performance.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: the two heating cable of leading of metal full-shield, comprise heater, be wrapped in the outer insulating barrier of heater, described insulating barrier is wrapped with metal screen layer, be provided with earth connection between described insulating barrier and the metal screen layer, blind hole between the described metal screen layer inside and outside wall, described metal screen layer is wrapped with oversheath.
As preferably, described oversheath is PVC material oversheath, and described oversheath is wrapped on the metal screen layer by Shooting Technique.PVC has good anticorrosion, anti-soda acid, anti-aging effect, and 100% waterproof.
As preferably, described insulating barrier is the double hyer insulation layer.The double hyer insulation layer can increase the useful life of heating cable.
As preferably, described insulating barrier is XLPE cross-linking polyethylene materials insulating barrier, and described insulating barrier is by making through the warm water crosslinking techniques of 90 degree after extruding again.Insulating material select with behind the high voltage bearing XLPE crosslinked polyethylene material insulation extrusion again through the 90 warm water crosslinking techniques of spending, crosslinking agent-silane in the insulating barrier is after suction, webbed cross-linked structure is given birth in the linear structure reaction, thereby improved the ageing-resistant performance of insulating material, the ability of mechanical performance and anti-environment, cross linked insulation electric wire have excellent electric property, good operational safety performance, more can effectively reduce electromagnetic radiation, be applicable to various heating purposes fully.
As preferably, described earth connection comprises the tin-coated copper heart yearn that 8 diameters are 0.4mm.Can effectively reduce electromagnetic radiation.
As preferably, described heater is the corronil conductor.Life-span reached more than 50 years, and power is unattenuated.
Beneficial effect:
The two heating cable of leading of the metal full-shield that the utility model adopts technique scheme to provide, mechanical strength is high, electromagnetic radiation is little, the expansion and the loose contact that cold and heat succeed each other and bring have been solved, can guarantee cable cold pin, the level and smooth welding transition of heating wire, ageing-resistant performance, mechanical performance and anti-environment functional has excellent electric property and good operational safety performance.
