Description

Electric scissor truck cable

Technical Field

The utility model relates to a cable construction's technical field specifically is an electric scissors car cable.

Background

Along with the modernization rhythm becoming faster and faster, China also becomes more and more demanding on city construction, and the pace is rapidly advanced. Because of the demands of the industry, there is also an increasing need for high-altitude operating environments. In consideration of work efficiency and work safety, the scissor vehicle is special equipment for high-altitude operation and has become a main force. However, the cable used by the existing scissors vehicle has short service life and can not meet the long-term use requirement of the scissors vehicle

Disclosure of Invention

In order to the problem, the utility model provides an electric scissors car cable, it has high fire-retardant, high flexibility, low temperature resistant to resistant oily and the outdoor characteristics of using of adaptation have guaranteed the long-term user demand of scissors car.

The utility model provides an electric scissors car cable which characterized in that: it includes that the cross section that outside-in arranged in proper order is the annular sheath of circle, winds the covering, be provided with three power cords, three signal group of group around the intracavity of covering, every group signal group is formed by two independent signal line pair twist combinations, still be provided with a plurality of PP ropes in the intracavity, three power cord, three group signal group, a plurality of the equivalent periphery anchor ring cladding that PP rope combination formed has around the covering, the sheath specifically is made for thermoplastic rubber material.

It is further characterized in that: after the three power lines and the three signal line groups are twisted to form an integral structure, and corresponding PP ropes are arranged between adjacent line bodies during twisting, the stability and reliability of the whole structure are ensured;

the PP rope is a reinforced halogen-free flame-retardant PP rope, so that the flame-retardant effect is ensured;

each power line comprises a central conductor and an outer insulating layer, wherein the outer insulating layer is made of thermoplastic rubber materials, and the central conductor is made of flexible multistrand 6-class fine conductors;

the center conductor is made of soft multi-strand class 6 fine conductor with monofilament diameter of 0.10mm, which makes the cable highly flexible.

After the utility model is adopted, three power lines and three groups of signal lines are arranged in the inner cavity of the wrapping layer, each group of signal lines is formed by combining two independent signal lines in a pair-twisting way, a plurality of PP ropes are also arranged in the inner cavity, the wrapping layer is wrapped on an equivalent peripheral ring surface formed by combining the three power lines, the three groups of signal lines and the plurality of PP ropes, and the sheath is made of thermoplastic rubber material; the cable has the characteristics of high flame retardance, high flexibility, low temperature resistance, oil resistance and adaptability to outdoor use, and long-term use requirements of the scissor truck are met.
