Background

In the occasion that the equipment unit needs to move back and forth, in order to prevent the cable from tangling, abrasion, pulling off, hanging and scattering, the cable is often put into a cable drag chain to form protection for the cable, and the cable can also move back and forth along with the drag chain. When the drag chain cable is used, the drag chain cable needs to move, bend and drag back and forth, the core of the cable is easy to break, and especially in a low-temperature environment, common insulating and sheath materials are easy to harden and become brittle in the low-temperature environment, so that the service life of the cable is greatly reduced.

Chinese patent: 105575510B discloses a novel drag chain cable at 2018-07-03, which comprises a wire core and a drag chain ring; the drag chain ring is in a flat ring cylinder shape, bar magnets extending along the axial direction of the drag chain ring are uniformly distributed in the circumferential direction of the drag chain ring, and the arrangement directions of magnetic poles of the bar magnets are consistent; translation wheels are further mounted on the outer ring surface of the towing chain ring at equal intervals, and the wheel surface of each translation wheel passes through the axis of the towing chain ring; annular grains are engraved on the inner ring surface of the drag chain ring; the cable has simple structure and is convenient to store and use; extension, translation that can be swift can realize the side simultaneously and move, can show improvement work efficiency. However, in a low-temperature environment, common insulating and sheathing materials are easy to harden and become brittle in the low-temperature environment, so that the service life of the cable is greatly reduced.

SUMMERY OF THE UTILITY MODEL

To prior art exist traditional still exist be under microthermal environment, ordinary insulating and sheath material become fragile at the easy sclerosis under low temperature environment, make the life greatly reduced's of cable technical problem, the utility model provides a soft low temperature resistant crooked tow chain flexible cable.

In order to solve the technical problem, the utility model discloses the technical scheme who takes does: the utility model provides a soft low temperature resistant crooked tow chain flexible cable, includes the sinle silk, the sinle silk includes the conductor, the conductor is the thin soft copper wire of national standard sixth class, the crowded package in the outside of conductor has low temperature resistant butyronitrile polyvinyl chloride composite insulation layer, and all sinle silks overlap through the non-woven fabrics band and wrap around the package, and the space department in the non-woven fabrics band is filled there is the polypropylene filling rope, and the crowded package in the outside of non-woven fabrics band has low temperature resistant butyronitrile polyvinyl chloride composite oversheath.
