The waterproof layer that sets up increases the waterproof performance of cable, prevents into water and causes the corruption to cable inside, influences the use, and the flame retardant coating of setting can ensure that the cable is incombustible or difficult burning in flame, and can still keep normal operating in the certain time, and the oversheath of setting mainly plays mechanical enhancement and anticorrosion effect.

The beneficial effects of the utility model are that:

1. through the arranged guide fixing ring, the thin steel rope and the fixing claws, the guide fixing ring can limit the thin steel rope when the cable is bent, so that the thin steel rope is prevented from supporting the sheath, and the thin steel rope is prevented from generating displacement and abrasion to the interior of the cable;

2. the water-meeting color-changing ink which is smeared when meeting water through the color-changing cotton threads which are arranged can change color, and only the color-changing cotton threads inside the transparent cover need to be observed, so that whether the water resistance of the cable is normal or not can be judged.
