Abstract
The utility model discloses an automatically-temperature-controlled heating cable, which is composed of insulating power wire cores, a nano flame retardant insulating layer, a steel-tape armoring layer and a heating wire core, wherein the insulating power wire core is formed by coating a plurality of tin-plated copper core stranded conductors on a flame retardant glass fiber inner core, and the two insulating power wire cores are symmetrically coated in a horizontal mode by a ceramic insulating layer; the heating wire cores is arranged at the middle of the ceramic insulating layer and located between the two insulating power wire cores; the heating wire core is externally coated by a thermal insulation shielding tape; the steel-tape armoring layer is coated outside the ceramic insulating layer and the thermal insulation shielding tape; and the nano flame retardant insulating layer is extruded on the steel-tape armoring layer. The automatically-temperature-controlled heating cable is reasonable in structural design, good in temperature compensation performance, fireproof, high temperature resistant, tension resistant and high in structural strength.
Description
Technical field
The utility model relates to cable, relates in particular to a kind of self controlled heating cable.
Background technology
Cable is in the development of the national economy, and handling cable and the carrier diffusing information, played huge effect the most, with
The quickening of urbanization process, the fast development of electric power transmission and communication, makes people more and more higher to the requirement of electric wire, not only requires cable to have the feature of safety and environmental protection, and has lower cost.Existing self controlled heating cable, its pull resistance is poor, while being subject to larger pulling force, easily damages, and also temperature-compensating poor-performing, structural strength is low, non-refractory, and fire protecting performance is poor.
Utility model content
According to above-mentioned situation, the utility model object is to provide a kind of self controlled heating cable.
Scheme of the present utility model is as follows: a kind of self controlled heating cable, it is made up of insulated power core, nano flame retardant insulating barrier, steel-tape armouring layer and heating core, and described insulated power core is coated on combustion-proof glass fiber inner core and is formed by multiply tin-coated copper core stranded conductor; It is coated that ceramic insulating barrier thoroughly does away with edge power core horizontal symmetrical two; In the middle of described ceramic insulating barrier, be provided with heating core, be positioned in the middle of two eradication edge power cores; Described heating core is coated with thermal stabilization shield band; Described steel-tape armouring layer is coated on ceramic insulating barrier and thermal stabilization shield band outside; Described nano flame retardant insulating barrier is extruded on steel-tape armouring layer.
The beneficial effects of the utility model: the utility model reasonable in design, temperature-compensating performance is good, fire prevention, high temperature resistant, tension, structural strength is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model,
Wherein: 1, nano flame retardant insulating barrier; 2, combustion-proof glass fiber inner core; 3, tin-coated copper core stranded conductor; 4, ceramic insulating barrier; 5, steel-tape armouring layer; 6, heating core; 7, thermal stabilization shield band.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, a kind of self controlled heating cable, it is made up of insulated power core, nano flame retardant insulating barrier 1, steel-tape armouring layer 5 and heating core 6, and described insulated power core is coated on combustion-proof glass fiber inner core 2 and is formed by multiply tin-coated copper core stranded conductor 3; It is coated that ceramic insulating barrier 4 thoroughly does away with edge power core horizontal symmetrical two; In the middle of described ceramic insulating barrier 4, be provided with heating core 6, be positioned in the middle of two eradication edge power cores; Described heating core 6 is coated with thermal stabilization shield band 7; Described steel-tape armouring layer 5 is coated on ceramic insulating barrier 4 and thermal stabilization shield band 7 outsides; Described nano flame retardant insulating barrier 1 is extruded on steel-tape armouring layer 5.
Although above embodiment of the present utility model has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present utility model and change and amendment; when its function producing does not exceed spiritual that specification contains yet, all should be within protection range of the present utility model.
