The on-load operation means that the on-load equipment maintenance operation is completed under the conditions that a power user does not stop power supply and the load of a power grid is not lost. When the distribution network live working process is carried out, the equipment with the insulated drainage wire is often needed, but when the insulated drainage wire is used, the insulated outer skin of the insulated drainage wire cannot directly contact with the cross arm, and extra insulation shielding is needed. The insulated drainage wire is a key tool for load transfer in a load-carrying operation, and the measures for fixing and preventing the insulated drainage wire from swinging are particularly important.
When the insulated drainage wire is used, because two ends of the insulated drainage wire are connected in the voltage class of 10kV, the insulated outer skin can not directly contact with a grounding body, and extra insulated shielding is needed, when the insulated drainage wire is used for operation, an insulated blanket is used for insulated shielding on a path through which the insulated drainage wire passes, and reliable isolation between the insulated drainage wire and different potentials is ensured. In addition, because the insulated drainage wire has certain weight, when the insulated drainage wire is connected on a 10kV overhead line, in order to prevent the wire clamp of the insulated drainage wire from being stressed too much, the insulated drainage wire must be reliably fixed at a proper position.

However, the above method has the following disadvantages:
1 when the existing insulated drainage wire is operated, the surrounding charged body and the grounding body are shielded by the rubber pad and the insulating blanket in an insulating way, and the shielding process takes a long time.
2 when shielding the surrounding charged body and the grounding body, the phenomenon of loose shielding may occur, and there is a potential safety hazard.
