Abstract
The utility model relates to a high-performance heating cable which comprises a PVC sheath. A metal shielding layer is arranged on the inner wall of the PVC sheath, two multi-strand heating wires are arranged inside the metal shielding layer, a Teflon protective layer is arranged on the outer wall of each multi-strand heating wire, and a cross-linked polyethylene protective layer is arranged on the outer wall of the Teflon protective layer. The high-performance heating cable provided by the utility model is simple in structure. The two multi-strand heating wires can form a loop by themselves, thereby being convenient in operation. The flexibility and tensile properties are improved. In addition, the Teflon protective layer effectively improves heat resistance and corrosion resistance performance of the heating cable.
Description
Technical field
The utility model relates to a kind of high-performance heating cable.
Background technology
Traditional in the market heating cable only has single heating metal main line usually, but the one of which end is connected this cold lead abbreviation cold line with the cold lead of energized.The outside protective layer of this heating metal main line outwards is provided with metallic shield and PVC sheath successively from the lining, the PVC sheath is that soft polyvinyl chloride expands and overlaps, but metallic shield is except that as the usefulness of double as ground wire also the protective layer.Above-mentioned traditional heating cable though in engineering, be widely used, also exists weak point.Because this heating cable only has a heating metal main line, can not have the loop of one's own, desire constitutes the loop during construction need increase a lead in addition, uses inconvenient.Heating efficiency is also low, and the metallic shield of above-mentioned usefulness as sheath double as ground wire normally is made up of several shielding conductors or metallic sheath, because its suppleness is relatively poor, therefore in construction, has the disadvantage of frangible.The heating metal main line of this heating cable only has the three-layer protection layer, its heat-and corrosion-resistant poor-performing, so the incompatible long-time needs that use of this heating cable.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of high-performance heating cable simple in structure, easy to use.
The high-performance heating cable of the utility model; Comprise the PVC sheath; The inwall of said PVC sheath is provided with metal screen layer; The inside of metal screen layer is provided with two multiply heating-wires, and the outer wall of multiply heating-wire is provided with the Teflon protective layer, and the outer wall of Teflon protective layer is provided with the crosslinked polyethylene protective layer.
Compared with prior art the beneficial effect of the utility model is: the high-performance heating cable of the utility model is simple in structure; Two multiply heating-wires can have the loop of one's own; Easy to use, improved pliability and tensile property, and the Teflon protective layer has effectively improved the heat-and corrosion-resistant performance.
Description of drawings
Fig. 1 is the structural representation of the described a kind of high-performance heating cable of the utility model embodiment.
Among the figure:
1, PVC sheath; 2, metal screen layer; 3, multiply heating-wire; 4, Teflon protective layer; 5, crosslinked polyethylene protective layer.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
As shown in Figure 1; A kind of high-performance heating cable; Comprise PVC sheath 1, the inwall of said PVC sheath 1 is provided with metal screen layer 2, and the inside of metal screen layer 2 is provided with two multiply heating-wires 3; The outer wall of multiply heating-wire 3 is provided with Teflon protective layer 4, and the outer wall of Teflon protective layer 4 is provided with crosslinked polyethylene protective layer 5.
The high-performance heating cable of the utility model is simple in structure, and two multiply heating-wires can have the loop of one's own, and are easy to use, improved pliability and tensile property, and the Teflon protective layer has effectively improved the heat-and corrosion-resistant performance.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection range of the utility model.
