Abstract
The utility model discloses a self-temperature-control heating cable used at low temperature, which comprises two power buses arrayed in parallel. Each power bus consists of a plurality of silver-plated copper wires which are twisted with each other to form a bundle, a conducting layer is wrapped on the outside of each power bus, conducting plastics are extruded to form the conductive layers, an insulating layer and a shielding layer are sequentially wrapped on the outside of each conducting layer, tin-plated flat copper wires are woven to form each shielding layer, coverage of each shielding layer to each insulating layer is 90% at least, and a sheath layer is wrapped on the outside of each shielding layer. The conducting layers are formed by means of extrusion, conducting effect is improved, the structure is more compact, the tin-plated flat copper wires are woven to form the shielding layers, the coverage of each shielding layer to each insulating layer is 90% at least, and shielding performance of the cable is effectively improved.
Description
Technical field:
The utility model relates to the heating cable field, relates in particular to a kind of self controlled heating cable that is used under the low temperature.
Background technology:
Self controlled heating cable is named again from the temperature control accompanying-heat cable, makes heater with a kind of conducting polymer composite, and its heating power can be adjusted, control self each point temperature automatically and keep constant temperature.Specifically: self controlled heating cable is to be power source bus by two parallel copper stranded conductors, and the centre evenly is crowded with conducting polymer composite and is the heating core material.When the bus energized, the electric current cross-current is crossed the heating core material between two buses, and core material is heated up, and its resistance increases thereupon automatically.When the core material temperature was raised to certain value, resistance was greatly to the degree of almost blocking electric current, and the core material temperature no longer rises.Meanwhile, core material conducts heat to being heated system by sheath, and temperature descends, and when temperature dropped to certain value, resistance reduced gradually, and the core material heating temp rises.So move in circles, just can keep being heated the system steady temperature.
Temperature during self controlled heating cable energy volitional check heating, and can regulate power output automatically with the variations in temperature that is heated system, therefore it has changed when using traditional permanent power heater and need be heated the heating means that system is deacclimatized heater, accomplish to allow heater deacclimatize the system of being heated, allow repeatedly juxtaposition to use, not the phenomenon that heat spot can occur and burn.
Self controlled heating cable is widely used in the tracing thermal-insulating, anti-freezing, antifreeze etc. of pipeline, the storage tank of industrial enterprises such as oil, chemical industry, iron and steel, electric power; This cable is suitable for the pipeline tracing with general area, hazardous area and corrosion region.
The structure defective tightness of original heating cable, shielding properties are relatively poor, thereby practical application effect is relatively poor.The utility model adopts the conductive layer that extrudes moulding, and conductive effect improves, and structure is compact more; The screen that adopts zinc-plated flat copper silk braiding to constitute simultaneously, screen is not less than 90% to the rate of one deck in it, has strengthened the shielding properties of cable effectively.
The utility model content:
The purpose of this utility model provides a kind of self controlled heating cable that is used under the low temperature, has solved original practical effect, not compact problem of the construction of cable that influences cable owing to shield effectiveness is relatively poor effectively.
The technical solution of the utility model is as follows:
Be used for the self controlled heating cable under the low temperature, comprise two power source buss that are arranged in parallel, it is characterized in that: described power source bus is made of the mutual stranded bunchy of several silver-gilt copper wires, the described power source bus outside is enclosed with the conductive layer that conductive plastics extrudes formation, the described conductive layer outside is enclosed with insulating barrier, screen successively, described screen adopts zinc-plated flat copper silk braiding to constitute, described screen is not less than 90% to the coverage rate of insulating barrier, and the described screen outside is enclosed with restrictive coating.
The described self controlled heating cable that is used under the low temperature is characterized in that: it is polyolefin or fluoroplastics that described insulating barrier adopts material.
The utility model has the advantages that:
The utility model adopts the conductive layer that extrudes moulding, and conductive effect improves, and structure is compact more; The screen that adopts zinc-plated flat copper silk braiding to constitute simultaneously, screen is not less than 90% to the rate of one deck in it, has strengthened the shielding properties of cable effectively.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Be used for the self controlled heating cable under the low temperature, comprise two power source buss that are arranged in parallel 1, power source bus 1 is made of the mutual stranded bunchy of several silver-gilt copper wires, power source bus 1 outside is enclosed with the conductive layer 2 that conductive plastics extrudes formation, conductive layer 2 outsides are enclosed with insulating barrier 3, screen 4 successively, screen 4 adopts zinc-plated flat copper silk braiding to constitute, the coverage rate of 4 pairs of insulating barriers 3 of screen is not less than 90%, screen 4 outsides are enclosed with restrictive coating 5, and it is polyolefin or fluoroplastics that insulating barrier 3 adopts material.
