Abstract
The utility model discloses a cable in the electric technical field, which comprises the following components: a cable core, insulating layers, shielding layers, coating layers and an outer protective layer. The anti-combustion cable is technically characterized in that: the outer surface of the outer protective layer is provided with convex-concave patterns; because the convex-concave patterns can enlarge heat radiation area of the wire cable, the heat can be quickly radiated for preventing circuit breakage accident.
Description
Technical field
The utility model relates to a kind of technical field of electricity, relates in particular to a kind of electric wire.
Background technology
At present, outer mainly the plaing a part of the electric wire that people use insulated, and the function of heat radiation is not effectively designed, in the situation that electric current is excessive or voltage instability causes easily that heat can not leave as early as possible and the generation that causes cutting off the power supply.
Summary of the invention
The technical problems to be solved in the utility model is relatively poor in order to overcome prior art cable resistance to wear, holds incendive shortcoming, and the cable that a kind of resistance to wear is strong and heat dispersion is good is provided.
For achieving the above object, the utility model is by technical scheme as described below: a kind of cable comprises that cable core, insulating barrier, internal shield, belting layer, filler, external protection consist of.The utility model includes conductor cores to disclosed cable; conductor cores is surrounded by an insulating barrier outward, and at insulating barrier outer wrapping copper strip shielding layer, screen is wrapped with belting layer; each belting layer abuts against together and filler is set outside it, and external protection wraps cable.
In above-mentioned cable, cable core is copper conductor.
In above-mentioned cable, insulating barrier is the insulator that polyvinyl chloride is made.
In above-mentioned cable, internal shield is the copper strip shielding layer.
In above-mentioned cable, belting layer is the non-net polypropylene tearing material of opening.
In above-mentioned cable, be provided with low-smoke non-halogen flame-retardant rope filler between described belting layer and external protection.
In above-mentioned cable, external protection is that crosslinked polyethylene is made, and its outer surface is made semi-circular convex-concave surface by mould, in the situation that guarantee that it does not have acute angle, the surface area of semi-circular convex-concave surface is maximum, and manufacture craft is the most convenient, and not easy to wear.
In above-mentioned cable, described cable core is any one in single core, twin-core, three cores, multicore.
The beneficial effects of the utility model are; this cable is provided with semi-circular convex-concave surface at its external protection, has increased the contact area between external protection and air, is beneficial to heat radiation; be provided with the low-smoke non-halogen flame-retardant filler at belting layer and external protection nail, effectively conduct heat energy and prevent from catching fire.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
For making those of ordinary skill in the art more be expressly understood the purpose of this utility model, technical scheme and advantage are further elaborated the utility model below in conjunction with drawings and Examples.
With reference to shown in Figure 1; the utility model includes a plurality of conductor cores 1 to disclosed cable; each conductor cores is surrounded by an insulating barrier 2 outward; at insulating barrier 2 outer wrapping copper strip shielding layers 3; screen 3 is wrapped with belting layer 4 each belting layers 4 and abuts against together and arrange filler outside it, and external protection 5 wraps a core or multicore cable.
In the present embodiment, belting layer contains three cover cables core.In other embodiments, cable core can be in single core, three cores or multicore any one,
In one embodiment, cable conductor 1 is copper conductor.Cable conductor 1 also can be any material that is used as cable conductor that makes.Insulating barrier 3 can be made for adjudicate two cases together ethene, can be also other suitable materials,
In the present embodiment, gasket for packing adopts the non-net polypropylene tearing material of opening, can reduce the heat absorption capacity coefficient of material like this, particularly on the filler cells basis of original limit gap, leap high structural units in sky, increase center, press Structure Decreasing construction of cable part thermal resistivity by densification, the cable radiating effect is increased, can effectively prevent the overheated burning of cable like this, this area and the technical staff can understand, gasket for packing also can be made by asbestos, glass fiber or other polypropylene tearing materials.
In the present embodiment, external protection 5 is made by crosslinked polyethylene, and average thickness is not less than 5 millimeters, and thinnest part is not less than 5 millimeters, the anti-wear performance of raising and insulation property.For the external protection surface area is increased, can pull out semi-circular ridge design with mould, thereby increase its heat dispersion.
Claims (3)
1. a cable, be provided with at least 3 cables core, is provided with successively insulating barrier, internal shield, belting layer outside each cable core; be provided with filler between belting layer and external protection; external protection wraps all cables core, and its technical characterictic is, external protection is provided with semi-circular convex-concave surface.
2. cable as claimed in claim 1, be provided with the low-smoke non-halogen flame-retardant filler between belting layer and external protection.
3. cable as claimed in claim 1, external protection is made by crosslinked polyethylene.
