Abstract
The utility model discloses a weatherproof environment-friendly cable for the tropical region, which comprises a plurality of conductors wrapped by insulating layers respectively. The conductors wrapped by the insulating layers are stranded into a bundle to form a multi-core cable conductor, the outer sides of the conductors are wrapped by a wrapping layer formed by waterproof belting by means of wrapping, and a filling core formed by a waterproof gauze and a waterproof strap which are stranded into a bundle is arranged between the wrapping layer and the conductors. The outer side of the wrapping layer is sequentially wrapped by a woven layer, an inner sheath layer, an armor layer and an outer sheath layer, and protruding strip anti-slip lines are arranged on the inner wall and the outer wall of the inner sheath layer. The weatherproof environment-friendly cable for the tropical region is compact in structure, has advantages of damp and hot resistance, aging resistance, sunlight resistance, mould proofing, flexibility, environment protection and the like, and is beneficial to cable laying and mounting, adaptable to the severe environment in the tropical region, and safe in environment protection.
Description
Technical field:
The utility model relates to the electric wire field, relates in particular to a kind of torrid areas and uses weather-proof environment-friendly cable.
Background technology:
The structure of torrid areas cable: in copper conductor, insulating barrier, screen, armour, sheath etc. are arranged.Such cable of tradition often has fluorine, chlorine, nitrogen, lead, cadmium etc. owing to insulating barrier and restrictive coating employing is plastics or fluoroplastics material, produces public hazards materials such as a large amount of dense smoke, dioxin, acid gas during burning.
At present,, force the material of the commercial compliance with environmental protection requirements of cable factory to replace traditional material, make environment-friendly cable or what is called " cleaning cable " along with the reinforcement of science and technology development and environmental protection concept.The particularity of torrid areas climatic environment needs cable to have characteristics such as moisture-proof heat, ageing-resistant, sunlight resistance, mildew-resistant, softness and environmental protection, guarantees the fail safe of using.But the material that uses at present is difficult to satisfy fully simultaneously above-mentioned requirements.
On the other hand, the structure of traditional torrid areas cable is compact inadequately, makes that the useful life of cable is also shorter, and the frequency of replacing is also higher relatively.
The utility model content:
The purpose of the utility model provides a kind of torrid areas and uses weather-proof environment-friendly cable, and compact conformation has characteristics such as moisture-proof heat, ageing-resistant, sunlight resistance, mildew-resistant, softness and environmental protection, adapting to the torrid areas rugged environment, and can have Environmental Safety property.
The technical scheme of the utility model is following:
Weather-proof environment-friendly cable is used in the torrid areas; Comprise several conductors; Several conductors are enclosed with insulating barrier outward respectively; The stranded bunchy of several conductors behind the wrap insulate layer constitutes the multicore cable core, it is characterized in that: several conductors outside is enclosed with the lapping layer of the wrapped formation of twining package tape that blocks water, and is provided with the core of filling out of water blocking yarn and the stranded bunchy of waterstop between lapping layer and the several conductor; The described lapping layer outside is enclosed with braid, inner restrictive coating, armour, external sheath layer successively, and the inside and outside wall of described inner restrictive coating is provided with the anti-skidding line of strip projected parts.
Weather-proof environment-friendly cable is used in described torrid areas, it is characterized in that: the bundle strand/thigh that described several conductors the are tinned copper wire structure that tangles, and the stranded lay ratio of several conductors is 14-20, and the filament diameter of tinned copper wire is 0.2-0.5mm; The single wire fracture percentage elongation is not less than 15%.
Weather-proof environment-friendly cable is used in described torrid areas, it is characterized in that: described insulating barrier, interior external sheath layer material adopt the low halogen Halogen modification fluorubber of environment-friendly type.
Weather-proof environment-friendly cable is used in described torrid areas, it is characterized in that: described braid adopts the tinned copper wire braiding to constitute, and armour adopts the wrapped formation of galvanized steel strip.
Weather-proof environment-friendly cable is used in described torrid areas, it is characterized in that: the radical of described several conductors is 2-48.
Compared with present technology, the utility model beneficial effect is embodied in:
1. the utlity model has higher flexibility, bending radius is not more than 2-4 times of the outside diameter of cable, helps cable laying and installs;
2. the finished cable temperature resistant grade of the utility model reaches 250 ℃, has improved the ampacity and the cable overload capacity of cable;
3. insulation in the utility model and sheath material adopt low smoke and zero halogen modification fluorubber, satisfy low cigarette, fire-retardant, requirements such as moisture-proof is warm, ageing-resistant, sunlight resistance, mildew-resistant;
4. adopt the protective layer of galvanized steel strip in the utility model, can avoid the direct down possibility of laying of installing of daylight out of doors as sheath.
5. the utlity model has anti-mineral oil, fuel oil resistance again, fire-retardant oxygen index reaches 48.
