The present invention discloses a fiber surface treatment composition, characterized in that the composition is comprised of a silane coupling agent, a polymer and a water repellent agent, wherein the polymer is a copolymer of a polyurethane/acrylic acid polymer, wherein the acrylic polymer is selected from the group consisting of polyacrylic acid, polyacrylates or acrylic acid-acrylic acid ester copolymers. The invention also discloses an insulating fiber having the composition on its surface, the preparation method for it, and an insulating yarn and an insulated cord. The insulated fibers, yarns and ropes of the invention have the advantages of moisture resistance, washing resistance, ultraviolet aging resistance and the like. Particularly, the insulated ropes can be applied to the charging work of transmission lines, especially the UHV transmission lines.

A device for servicing live power lines, including: a main body, two primary mechanical arms, two telescopic arms, a terminal device, an auxiliary mechanical arm, and a monitoring system. A travelling wheel mechanism, an equipotential wheel, and a first clamping jaw are disposed on the upper end of each telescopic arm. The two primary mechanical arms are symmetrically disposed on two sides of the main body, respectively. The two telescopic arms are vertically disposed on two ends of the main body, respectively, and are capable of telescoping upward and downward. The auxiliary mechanical arm is disposed and adapted to move transversely on the main body. The main body is driven by the travelling wheel mechanism to travel on the high voltage transmission line. The first clamping jaw clamps the high voltage transmission line for locating the main body.
