The insulating operation platform 6 and the insulating guardrail 13 can ensure the safety of the power line repair personnel during live-line operation. The insulating operation platform 6 and the insulating guardrail 13 are both made of glass fiber reinforced plastic rectangular hollow structural sections which are pultruded by glass fiber and epoxy resin as main materials, the withstand voltage level is 220KV, and the insulating operation platform can withstand the power frequency test voltage of 450kV/2.1 m.
In the invention, because the electrical power rush-repair personnel need to perform bypass access of the high-voltage lead 23, namely, the high-voltage lead 23 pre-installed with the wire clamp is connected with the high-voltage transmission line at high altitude through the insulating rod, the labor intensity of the electrical power rush-repair personnel accessing the high-voltage lead 23 at high altitude by using the insulating rod is higher due to the heavy weight of the high-voltage lead 23, and the operation error phenomenon is easy to occur due to the overweight of the high-voltage lead 23. In order to reduce the labor intensity of the power line repair personnel and improve the bypass access efficiency of the high-voltage lead 23, the high-voltage lead 23 is fixed in a non-return mode, so that the high-voltage lead 23 can only be conveyed upwards, and potential safety hazards caused by gravity falling of the high-voltage lead 23 are prevented.

When the cable clamping device is used, the cable clamping block 20 is firstly pushed to the middle of the cable clamping block sliding groove 16, then the high-voltage lead 23 penetrates through the cable clamping block sliding groove 16 from the opening 19 below the cable clamping block sliding groove 16 through the cable clamping block 20, the end part of the high-voltage lead 23 is positioned outside the opening 18 above the cable clamping block sliding groove 16, when the cable clamping part 15 is vertically arranged, the two cable clamping blocks 20 slide downwards under the action of gravity, and the two cable clamping blocks 20 are tightly attached to the surface of the high-voltage lead 23 because the outer sides of the two cable clamping blocks 20 are inclined planes with the same slope as that of the cable clamping block sliding groove 16. At this time, if the high voltage lead 23 falls down under the action of gravity, the two cable clamping blocks 20 will fall down together with the high voltage lead 23 under the action of friction force, and will clamp the surface of the high voltage lead 23 and limit the high voltage lead 23 to prevent the high voltage lead 23 from falling continuously due to the inclined surface, thereby playing a role of non-return.

The arc surface of the opposite side of the two cable clamping blocks 20 is provided with an insulating rubber layer to improve the friction force with the high-voltage lead 23, thereby achieving better non-return and anti-skid effects.
