Description
Technical field
The utility model belongs to field of cables, particularly relates to a kind of anti-to pull water-proof cable.
Background technology
At present, along with the raising day by day of China's rapid development of economy and scientific and technological level, the consumption of cable constantly increases, and also proposes higher requirement to the quality of cable.But present general cable also exist shielding properties not high, anti-pull strong, core is firm not, the waterproof a series of problem such as not and not environmentally.Such as cable adopts polythene material but polyethylene is combustible material, containing halogen, once breaking out of fire, will discharge toxic gas, bring harm.
Only meet the requirements, just can better ensure the production and application of cable.
Utility model content
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of good conductivity, low smoke and zero halogen environmental protection, anti-pulls, core is firm, waterproof shield is high pulls waterproof three core pair twist screened cable.
The utility model is taked following technical scheme to realize: a kind of resisting pulls water-proof cable, it comprises master core, belting layer, internal shield, insulating barrier, outer shielding layer and protective sleeve, described master core is four groups, described master core is formed by three zinc-plated insulated wire cores pair twists, described zinc-plated insulated wire cores is by fine copper inner wire, the outer conductor composition of interior skinning cortex and the braiding of albronze silk, described belting layer inside is provided with a reinforcement and a ground connection core, described reinforcement and described master core tangent, watertight composition is wrapped up between described belting layer and described internal shield, described watertight composition is made up of interior waterstop and outer water barrier.
Preferably, described internal shield is woven by multiply high-strength alloy copper wire outsourcing annealed wire to form, and described outer shielding layer is woven by the outer aluminium foil of silver-gilt copper wire to form.
The utility model has following beneficial effect in sum: the utility model good conductivity, long service life, low smoke and zero halogen environmental protection, core is firm, resists and pulls, be widely used in the fields such as computer, communication, generating, metallurgy, oil, chemical industry, anti-oxidant, shielding properties is strong, meanwhile, also possesses higher waterproof ability.

Wherein, described reinforcement 2 is tangent with described master core 1, and wrap up watertight composition between described belting layer 3 and described internal shield 5, described watertight composition is made up of interior waterstop 4A and outer water barrier 4B.
As preferred version of the present utility model, protective sleeve 9 of the present utility model is low smoke and zero halogen materials of organic silicon ribbon containing mica, ceramic fibre.
As preferred version of the present utility model, described reinforcement 2 of the present utility model is inner polyurethane of filling nickel coated steel wire.
As preferred version of the present utility model, insulating barrier 7 of the present utility model adopts not drip to fill the fluorubber of glue.
As preferred version of the present utility model, internal shield 5 of the present utility model is woven by multiply high-strength alloy copper wire outsourcing annealed wire to form.
As preferred version of the present utility model, outer shielding layer 8 of the present utility model is woven by the outer aluminium foil of silver-gilt copper wire to form.
The permission bending radius of this cable is 16 times of the outside diameter of cable; The shielding rejection coefficient of this cable is less than 0.6.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
