Furthermore, the number of the core wires is two, and each core wire adopts a stranded fine copper wire stranded conductor.

Further, the outer protection sleeve adopts a PUR protection layer, and the inner protection sleeve adopts a PVC insulation layer.

Furthermore, the reinforcing metal wire is composed of a plurality of metal wires which are arranged in a triangular shape, and the plurality of metal wires are fixedly bonded.

Furthermore, the bag belt is wrapped by non-woven fabrics.

Furthermore, the filling body adopts PP ropes and cotton threads.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses an interior lag and the outer lag that is equipped with, outer lag adopt the PUR inoxidizing coating, and interior lag adopts the PVC insulating layer, is convenient for improve the resistant oily of cable, high temperature resistant and performance such as insulating to improve the security of using.

2. The utility model discloses and through installing between the interior lag and strengthening connecting portion and strengthening the wire, can strengthen the inside structural strength of cable, be convenient for improve the ability that the tensile was dragged, be favorable to improving its life.
