Description
technical field:
The present invention relates to electric wire process technology, particularly relate to the temperature self controlled electrically-heated cable of a kind of engine.
background technology:
In the last few years, due to the frequent generation of natural calamity, especially in the winter time, in the north of cold, fast reaction seems particularly important.This just needs breakdown lorry, aircraft, when receiving order, it is on-the-spot that the very first time of taking action at once arrives disaster area.Mostly because of cold weather, engine temperature is too low can not be started at once, delays best rescue time; Or when the backspace of scene, disaster area, engine there will be the phenomenon of starting difficulty equally, does not still have rational cable to address this problem at present.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide the temperature self controlled electrically-heated cable of a kind of engine, novel in structural design, effectively can solve the too low problem that can not start at once of engine temperature.
Technical scheme of the present invention is as follows:
The temperature self controlled electrically-heated cable of engine, it is characterized in that: comprise the self-temperature-limiting heating strip that some intervals are placed, the belt distance of described self-temperature-limiting heating strip is generally at 30mm ~ 35mm, the overcoat that the upper and lower surface of self-temperature-limiting heating strip is coated with aluminium foil glass fiber fabric successively, industrial Tarpauling fabric is formed, is wherein provided with the heat-insulation layer that polyethylene is formed between the aluminium foil glass fiber fabric of lower floor and the overcoat of industrial Tarpauling fabric.
The temperature self controlled electrically-heated cable of described engine, it is characterized in that: described self-temperature-limiting heating strip comprises two power supply buses of parallel placement, two power supply buses are formed by the tin-coated copper strand bundle strand that 48 diameters are 0.15mm, spacing 4.3 ~ 4.5mm between two power supply buses, two power supply buses are coated with heating layer, the thermoplastic elastic body insulated restrictive coating that conductive polymer PTC heating material is made outward successively.
The temperature self controlled electrically-heated cable of described engine, is characterized in that: the thickness of the heat-insulation layer that described polyethylene is formed is generally 18 ~ 22mm.
The temperature self controlled electrically-heated cable of described engine, is characterized in that: the nominal thickness of the heating layer of described self-temperature-limiting heating strip is generally at 0.5 ~ 0.7mm.
The temperature self controlled electrically-heated cable of described engine, is characterized in that: the thermoplastic elastic body insulated restrictive coating nominal thickness of described self-temperature-limiting heating strip generally at 0.6 ~ 0.8mm, overall dimension: 9.9mm × 4.2mm.
Advantage of the present invention is:
Novel in structural design of the present invention, by self-temperature-limiting heating strip, aluminium foil glass fiber shielding cloth, polyethylene heat-insulation layer, technique Tarpauling composition, most high maintenance temperature 70 C can be ensured, rated voltage 220V, insulation resistance 20M Ω when 20 DEG C, after order received by aircraft, opening the control switch of temperature self controlled electrically-heated cable in time when taking off, just can successfully take off by ato unit.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is self-temperature-limiting heating strip structural representation of the present invention.
embodiment:

The temperature self controlled electrically-heated cable of engine, comprise the self-temperature-limiting heating strip 1 that some intervals are placed, the belt distance of self-temperature-limiting heating strip 1 is generally at 30mm ~ 35mm, the overcoat 3 that the upper and lower surface of self-temperature-limiting heating strip 1 is coated with aluminium foil glass fiber fabric 2 successively, industrial Tarpauling fabric is formed, is wherein provided with the heat-insulation layer 4 that polyethylene is formed between the aluminium foil glass fiber fabric of lower floor and the overcoat 3 of industrial Tarpauling fabric.
Self-temperature-limiting heating strip 1 comprises two power supply buses 1-1 of parallel placement, two power supply buses 1-1 are formed by the tin-coated copper strand bundle strand that 48 diameters are 0.15mm, spacing 4.3 ~ 4.5mm between two power supply buses 1-1, two power supply buses 1-1 are coated with heating layer 1-2, the thermoplastic elastic body insulated restrictive coating 1-3 that conductive polymer PTC heating material is made outward successively.
The thickness of the heat-insulation layer 4 that polyethylene is formed is generally 18 ~ 22mm, preferred 20mm.
The nominal thickness of the heating layer 1-2 of self-temperature-limiting heating strip is generally at 0.5 ~ 0.7mm.
The thermoplastic elastic body insulated restrictive coating 1-3 nominal thickness of self-temperature-limiting heating strip 1 generally at 0.6 ~ 0.8mm, overall dimension: 9.9mm × 4.2mm.
The present invention is coiled into S type by the distance of interband 30mm ~ 35mm according to the shape of engine shape assumption diagram by from limit temperate zone in the process used, and surrounding gets rid of limit 10mm ~ 15mm, and connect power line from limit first section of temperate zone, initial and end end end socket will carry out water-proofing treatment; Heat-insulation layer 4 one side outwardly that polyethylene is formed in the one side with extraneous contact.
