Abstract
The present invention relates to a kind of spring cable, comprise the many light transmitting fibers being positioned at central authorities, what the outer interval of described many light transmitting fibers was adjacent is wound with the first spiral empire silk and the second spiral empire silk, and described first spiral empire silk and the second spiral empire silk periphery are provided with sheath.Described first spiral empire silk is made up of black polyethylene insulating material; Described second spiral empire silk is made up of white polyethylene insulating material.Spring cable of the present invention, it adopts soft polyethylene helical empire silk and soft oversheath, makes it not only have higher tensile strength, and counter-bending, bending performance is excellent, cable is also more soft, and the scope of application is wider.
Description
Technical field
The invention belongs to the technical field of cable design and manufacture, the present invention relates to a kind of spring cable in particular.
Background technology
Along with China's sustain economic increases fast, also for the development of line cable industry provides huge market outlook, the temptation that Chinese market is strong, the world is made all sight to be focused on Chinese market, in the decades that reform and opening-up is short, the huge productive capacity that Chinese cable manufacturing industry is formed allows the world regard with special esteem.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.
At present, wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety Service Efficiency and home market occupation rate are all more than 90%.And worldwide, the Chinese electric wire gross output value exceedes the U.S., become first electric wire producing country in the world.Along with Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.
In the prior art, optical cable is used in a large number by all trades and professions, and what optical cable of the prior art adopted usually is the mechanical property that compound aluminium strip, steel band etc. strengthen optical cable, but thisly adds strong method and also cause bending pliability not ideal enough.

In order to solve the above-mentioned technical matters existed in prior art, the object of the present invention is to provide a kind of spring cable.
To achieve these goals, the invention provides following technical scheme:
A kind of spring cable, comprises the many light transmitting fibers being positioned at central authorities, be wound with the first spiral empire silk and the second spiral empire silk, and described first spiral empire silk and the second spiral empire silk periphery is provided with sheath outside described many light transmitting fibers.
Wherein, described first spiral empire silk is made up of black polyethylene insulating material; Described second spiral empire silk is made up of white polyethylene insulating material.
Wherein, the adjacent setting of described first spiral empire silk and the second spiral empire silk interval.
Compared with prior art, the present invention has following beneficial effect:
Spring cable of the present invention, it adopts soft polyethylene helical empire silk and soft oversheath, makes it not only have higher tensile strength, and counter-bending, bending performance is excellent, cable is also more soft, and the scope of application is wider.
