Advantages:

（1）The outer armor layer adopts fan-shaped steel wire, the cross-sectional area is increased compared with the round steel wire, and the carrying capacity of the cable is increased by 20% compared with the common cable.

（2）The fan-shaped steel wire can effectively increase the friction area of the steel wire, and the wear resistance of the cable is improved, which indirectly increases the service life of the cable. At the same time, this type of cable can prevent the wire from "jumping", "bulging" and other phenomena that cause abnormal damage to the cable.

（3）The appearance of the cable is smooth and wear-resistant, forming a pure circular structure, which can prevent the cable from encountering obstruction and jamming during the application.

（4）The anti-corrosion sealing medium is coated between the inner and outer armor layers, which can reduce liquid corrosives from entering the inside of the cable, prevent the inside of the cable from being corroded, ensure the tensile strength of the cable, increase the service life of the cable, and effectively prevent underground oil overflow to the well surface, it forms a better protection for the environment.
