Background

An overhead cable is an overhead conductor provided with an insulating layer sheath, and when a conductive member needs to be installed on the overhead cable, the insulating layer sheath of the installation part of the overhead cable is generally required to be stripped. Because the overhead cable is installed in the air, the common automatic peeling device cannot be applied to the overhead cable to peel off the outer skin of the insulating layer of the overhead cable; therefore, at present, operators generally wear insulating gloves and hold wire strippers to manually strip the insulating layer sheaths at the installation parts of the overhead cables. The existing operation mode for manually stripping the insulating layer sheath of the overhead cable has high labor intensity of stripping operation and low stripping operation efficiency; and operating personnel is close to the aerial cable, has the potential safety hazard of electrocution easily.
