During the maintenance of HV transmission line

the reasonableness of short-circuit grounding wires is the major determinant of the safety of people and power grid. In this paper

a new kind of anti-lock clamp of short-circuit grounding wires for HV transmission line is proposed. The kinematics parameters of the lower extreme point of the left arm are obtained by establishing and solving the kinematics equation of the left arm. Secondly

the clamping force of the left arm has been analyzed theoretically. Meanwhile

the influence of main parameters to the clamping force between the holding rod and HV transmission line

the switching efficiency of the holding rod has been analyzed by correlative software. The conclusion shows the wire end clamp has high reliability and switching efficiency.
