Abstract
The utility model discloses an automatically temperature-controllable heating cable in a high-temperature series, which comprises two parallel power source buses. A tin coating layer which is 0.18-0.80mm in thickness is coated outside each of the two power source buses prior to that the two power source buses are wrapped with a conductive layer formed by conductive plastics through extrusion, the conductive layer is sequentially wrapped with an insulating layer and a shielding layer, the shielding layer is made of tinned copper wires through weaving, the rate of the shielding layer covering the insulating layer is no lower than 85%, the shielding layer is wrapped with a shielding protective sleeve layer, a framework is circularly arranged in the protective sleeve layer and is made of steel wires to a net shape through weaving and coiled into a drum shape, and the insulating layer and the protective layer are made of fluoroplastics. The automatically temperature-controllable heating cable is higher in conductive effect by the aid of the conductive layer formed through extrusion, and simultaneously, the shielding layer is made of tinned flat copper wires through weaving, and the rate of the shielding layer covering the inner layer is no lower than 85%, so that the shielding performance of the cable is effectively enhanced. Moreover, the mechanical performance of the cable is enhanced by the aid of the framework which is circularly arranged in the protective sleeve layer of the cable.
Description
Technical field:
The utility model relates to the heating cable field, relates in particular to a kind of self controlled heating cable of high temperature series.
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 through 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 ability 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 let heater deacclimatize the system of being heated, allow repeatedly juxtaposition to use the phenomenon that heat spot can not 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.Simultaneously cable see that extrusion performance is relatively poor, the power source bus of cable receives ambient pressure and problem such as deform easily.
The utility model content:
The purpose of the utility model provides a kind of self controlled heating cable of high temperature series, 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 scheme of the utility model is following:
The self controlled heating cable of high temperature series comprises two power source buss that are arranged in parallel, and it is characterized in that: two power source buss scribble tin coating outward respectively; Tin coating thickness is 0.18-0.80mm; Two power source buss outsides that scribble behind the tin coating are enclosed with the conductive layer that conductive plastics extrudes formation, and the conductive layer outside is enclosed with insulating barrier, screen successively, and screen adopts the tinned copper wire braiding to constitute; Screen is not less than 85% to the coverage rate of insulating barrier; The screen outside is enclosed with restrictive coating, is provided with a ring framework in the restrictive coating, and skeleton is that braided steel wire is the netted tubular formation that is rolled into.
The self controlled heating cable of described high temperature series is characterized in that: it is fluoroplastics that described insulating barrier, restrictive coating adopt material.
The utility model has the advantages that:
The utility model adopts the conductive layer that extrudes moulding; Conductive effect improves, the screen that adopts zinc-plated flat copper silk braiding to constitute simultaneously, and screen is not less than 85% to the rate of one deck in it; Strengthened the shielding properties of cable effectively; In addition, be provided with a ring framework in the cable cover(ing) layer, increased the mechanical performance of cable.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The self controlled heating cable of high temperature series comprises 1, two power source bus of two power source buss, the 1 outer tin coating 2 that scribbles respectively that is arranged in parallel; Tin coating 2 thickness are 0.18-0.80mm, and two power source bus 1 outsides that scribble behind the tin coating 2 are enclosed with the conductive layer 3 that conductive plastics extrudes formation, and conductive layer 3 outsides are enclosed with insulating barrier 4, screen 5 successively; Screen 5 adopts the tinned copper wire braiding to constitute; The coverage rate of 5 pairs of insulating barriers 4 of screen is not less than 85%, and screen 5 outsides are enclosed with restrictive coating 6, is provided with a ring framework 7 in the restrictive coating 6; Skeleton 7 constitutes for braided steel wire is the netted tubular that is rolled into, and it is fluoroplastics that insulating barrier 4, restrictive coating 6 adopt material.
