Abstract

The utility model discloses a novel heating cable which is environmentally friendly and is simple in processing and low in cost. The novel heating cable consists of an outer skin (1), a metallic shield (2), a metal composite film (3), a polyester film (4), a heating wire (5), a circuit wire (6) and a cable insulation packing (7) and is characterized in that the heating wire (5) and the circuit wire (6) are wounded together and wrapped by the polyester film (4), the outer part of the metal composite film (3) is wrapped by the netty metallic shield (2), and the whole cable body is wrapped by an insulating jacket (1). A ground wire is replaced by the netty metallic shield (2), and the netty metallic shield (2) can realize uniform heat conduction and shield the electromagnetic radiation and is composed of metal wire bodies. Only one polyester film (4) layer is used for wrapping the cable body, therefore, the technical process of the multi-layer wrapping is reduced; and the ground wire is replaced by the netty metallic shield (2), therefore, the electromagnetic radiation in the cable can be shielded.

Description

Novel heating cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of novel heating cable.

Background technology

Numerous industrial fields such as electric wire is widely used in energy traffic, information communication, builds a railway, city rail automobile, aviation metallurgy, petrochemical industry.China is a cable big country, but is not power.Accompanying-heat cable relies on import mostly on present market, but the inside of import cable uses silicon rubber to do the outer wrap layer of heating line and return line mostly.Silicon rubber difficulty on the production technology is big, the production cost height, and silicon rubber output is less at home, mostly rely on imports, this has just increased cost.The line cable industry concentration degree is low, dispersed technical resources, scientific and technological content is low, so some enterprise is an incompetent person or a person unequal to his task, and makes some fake and forged commodity, manufactures in a rough and slipshod way, uses inferior materials and turns out substandard goods, shoddy cable products, cause being easy to generate in the cable electromagnetic radiation of trace, can influence to some extent environment.

Summary of the invention

Technical problem according to above-mentioned proposition, the utility model proposes a kind of environmental protection, process the novel heating cable simple, that cost is low, form by insulating sleeve (1), metallic shield (2), metal composite film (3), polyester film (4), heating line (5), return line (6), cable insulation filler (7), the line that it is characterized in that generating heat kinks with return line is in the same place, heating line and return line outside are wrapped up by polyester film, the shielding of metal composite film outer wrap net metal is wrapped up whole line body by insulating sleeve.Net metal shielding replaces ground wire, with uniform heat conduction and can electromagnetic radiation shielding, and is done to constitute by the metal wire system.

The beneficial effects of the utility model are: heating line and return line outer wrap material are the cross-linking radiation material, the domestic a large amount of productions of this material, processing technology are simple, steady quality, advantage such as cheap, so not only can reduce technology difficulty but also can with about production cost.The utility model employing institute cable body all kinks design together, can only use one deck polyester film parcel line body just passable like this, reduce the technical process of several layers of parcel, and used the net metal shielding to replace ground wire, can the interior electromagnetic radiation of shielded type cable.Crust uses making such as soft insulating sheath or the poly-rare cl material of high-temperature material PVC, PE; shield at metal composite film outer wrap net metal; like this can more uniform heat conduction and can electromagnetic radiation shielding, can also better protection line body, play reduce pollute, the effect of environmental protection.Use the metal composite film parcel to play the characteristics that heat conduction on average improves heat dispersion, polyester film can the protective wire body.Cross-linking radiation is all wrapped up in heating line and return line outside, and the heating line uses alloy wire to make, and return line uses copper conductor to make.The inner filled glass fiber silk of whole cable, the net metal shielding uses the metal wire system to make the external wrap insulate sheath of whole line.The utility model can be worked between the 80-100 degree for a long time, about every meter cable per hour uses power as 20W.Can realize whole production domesticization fully like this, save the cost of 30%-35%, reduce the price of cable greatly.

Embodiment

According to shown in Figure 1, the utility model line body center is heating line (5) and return line (6), heating line (5) and return line (6) outer wrap adopt the cross-linking radiation material, and kink with cable insulation filler (7) and to be in the same place, cable insulation filler (7) can adopt materials such as PP rope, polyester belt, tinfoil paper band, glass fiber, cotton thread, the rope made of hemp.Coated outside one deck polyester film (4) then, then at polyester film (4) outer wrap metal composite film (3), in metal composite film (3) outer wrap net metal shielding (2), superscribe insulating sleeve (1) then, insulating sleeve (1) adopts rodent-proof material, avoids mouse to bite and causes cable bad.

Claims

1. novel heating cable, form by crust (1), metallic shield (2), metal composite film (3), polyester film (4), heating line (5), return line (6), cable insulation filler (7), it is characterized in that design heating line (5) and return line (6) kink together, use polyester film (4) parcel heating line (5) and return line (6), metal composite film (3) outer wrap net metal shielding (2) is by the whole line body of crust (1) parcel.

2. according to the described novel heating cable of claim 1, it is characterized in that net metal shielding (2) replaces ground wire, with uniform heat conduction and can electromagnetic radiation shielding, and do to constitute by the metal wire system.
