Along with China's sustain economic increases fast, the development for cable industry provides huge market prospects.Along with the continuous expansion of the industry sizes such as electric power, communication, track traffic, automobile and shipbuilding, the demand of electric wire is also being increased rapidly, electric wire industry from now on can predicted and also have huge development potentiality.But existing cable resistance to tension is very weak, often during the stressed elongation of cable, material occurs tired, and in the course of time, the quick aging of cable jacket layer, inner lead tensile phenomenon may occur.
Utility model content
The purpose of this utility model is to provide a kind of longitudinal elasticity tensile cable, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of longitudinal elasticity tensile cable, comprise fire-resistant isinglass belt lapping layer, soft copper band lapped shielding layer, spring, restrictive coating, first conductor, insulating jacket A, tin coating, thick copper lines, second conductor, copper mesh screen, fine copper wire, insulating barrier B and the 3rd conductor, described 3rd conductor is formed by arranging insulating jacket A outside thick copper lines, the cross section of the 3rd conductor is circular as leader cable, the bilateral symmetry of described 3rd conductor is provided with the first conductor and the second conductor, described first conductor and the second conductor are formed with fine copper wire outer cladding copper mesh screen by some, wherein be equipped with insulating barrier B outside fine copper wire, be wound with soft copper band lapped shielding layer outside described first conductor and the second conductor, described soft copper band lapped shielding layer outside is wound with fire-resistant isinglass belt lapping layer, and described soft copper band lapped shielding layer overcoat has restrictive coating, and the middle part of restrictive coating is embedded with spring.
As further program of the utility model: described copper mesh screen is woven by thin copper wire and makes net.
As the utility model further scheme: described thick copper lines outer surface is coated with tin coating.
Compared with prior art, the beneficial effects of the utility model are: realize by arranging the first conductor, the second conductor and the 3rd conductor the shunting that cable carries electric power, different current capacities can be met simultaneously, thus the insulating reliability of control cables is improved greatly, extend the useful life of control cables, and the first conductor, between the second conductor and the 3rd conductor by arranging copper mesh screen and soft copper band lapped shielding layer, conductor is not interfere with each other each other, equally not by external disturbance; Be embedded with spring at the middle part of restrictive coating, make restrictive coating tension and all there is elasticity, the overall resistance to tension improving cable.
