The utility model content:
To above-mentioned technical problem, the purpose of the utility model provides anticorrosion, the oil resistant heating cable of a kind of soft type, and reasonable in design can be used under adverse circumstances and can prolong cable useful life.
The technical scheme of the utility model is following:
Soft type is anticorrosion, the oil resistant heating cable, it is characterized in that: comprise cold line, hot line, described cold line, hot line all adopt the alloy heat generating silk; Wherein cold line adopts Contra wire, and hot line adopts nichrome wire, and cold line, hot line are enclosed with the inner insulating layer of polytetrafluoroethylmaterial material outward respectively; The stranded formation cable core of cold line, hot line of parcel inner insulating layer; Cable core is enclosed with external insulation layer, screen outward successively, is provided with channelizing line between external insulation layer and the screen, and screen is extruded with restrictive coating outward.
Anticorrosion, the oil resistant heating cable of described soft type is characterized in that: it is cross-linked polyolefin that described external insulation layer adopts material, and the degree of cross linking reaches 80%.
Anticorrosion, the oil resistant heating cable of described soft type is characterized in that: described channelizing line adopts 8 stranded formations of tinned copper wire.
Anticorrosion, the oil resistant heating cable of described soft type is characterized in that: described screen adopts the wrapped formation of aluminium foil strip, and coverage rate reaches 100%.
Compared with prior art, the utility model beneficial effect is embodied in:
1, the utlity model has anticorrosion, oil resistant excellent properties, especially be fit to use and use at rugged environments such as high burn into greasy dirts.
2, the utility model has been owing to adopted newly designed structure, two heat radiating structures of leading, and quality is superior, has eliminated the phenomenon that single cable is prone to produce the inductance eddy current effectively.
3, safe and reliable, radiationless: as to adopt high-performance PTFE material and anticorrosion, oil proof sheath, insulating properties, water proofing property, superior performance such as high temperature resistant, high pressure resistant, corrosion-resistant; Electromagnetic radiation has been eliminated in metallic shield effectively, product operation zero radiation.
4, material property is stable, and the inactivity decay: the exothermic material of this cable is the high-performance nickel-cadmium, good stability.
5, heating cable adopts spiral manufacturing process, has improved the pliability of cable greatly, and can effectively overcome the influence that differential settlement of buildings etc. causes cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Referring to Fig. 1:
Soft type is anticorrosion, the oil resistant heating cable, comprises cold line 1, hot line 2, and cold line 1, hot line 2 all adopt the alloy heat generating silk; Wherein cold line 1 adopts Contra wire, and hot line 2 adopts nichrome wire, cold line 1, the hot line 2 outer inner insulating layers 3 that are enclosed with polytetrafluoroethylmaterial material respectively; Cold line 1, the hot line 2 stranded formation cable cores of parcel inner insulating layer 3; Cable core is enclosed with external insulation layer 4, screen 5 outward successively, is provided with channelizing line 6 between external insulation layer 4 and the screen 5, the screen 5 outer restrictive coatings 7 that are extruded with.
It is cross-linked polyolefin that external insulation layer 4 adopts material, and the degree of cross linking reaches 80%.
Channelizing line 6 adopts 8 stranded formations of tinned copper wire.
After the utility model energising, hot line is sent out 2 heat, and 40～60 ℃ cold operation, is embedded in the heating cable in the packed layer, and mode and the far-infrared radiation mode of the 8-13 μ m that send of heat energy through heat conduction (convection current) passed to heated body.
The utility model links to each other with cold line 1 through the terminal box of water-tight; After cold line 1 two ends added voltage, electric current passed through in heating cable, owing to receive the obstruction of resistance; Electric energy is converted into heat energy and comes out with the form of radiation, and its heat efficiency is up to nearly more than 100%.
Insulating barrier (inner insulating layer, external insulation layer): the PTFE insulating material of selecting for use is that insulating properties and heat-resisting quantity are best in the whole organic substance.Owing to the existence of this insulating material, effectively reduce the contact temperature of cross-linked polyolefin, cross linked insulation is in the normal working temperature all the time, thereby has prolonged the useful life of insulating barrier.Hot line and cold and hot wire terminal place all coat PTFE, and extend to cold line section 2.5-3cm.Because the existence of contact resistance, joint the resistance often resistance than other positions are big, thereby caloric value is just big, the temperature higher position.The extension of cold line section PTFE also is in order to guarantee that enough insulating properties and insulating barrier have normal working temperature.The degree of cross linking reaches 80% cross-linked polyolefin external insulation, and heatproof 150 degree have good insulation property.Can reach more than 50 years useful life.
Screen 5: aluminum foil shielded, coverage rate reach 100% shielding electromagnetism.
Channelizing line 6:8 bar tinned copper wire is used for current drainage as channelizing line.
Restrictive coating 7: the tension silk silastic material sheath of heat-resisting 180 degree, protection cable and increase area of dissipation have outstanding anticorrosion, oil resistance.
The utility model application places very extensively both can be used as the main heating equipment of building, also can be used as the warm ground equipment that improves comfort level, can also be applied in fields such as industrial or agricultural, was the antifreeze companion's heat of equipment such as tank body, pipeline.Install simply, operating cost is lower, and good social benefit and economic benefit are arranged, and heating cable heating is to realize zero discharge, pollution-free green environment-friendly type heating system, is beneficial to " peak load shifting " to city thermoelectricity system.
