At present,the installation of insulation protective covers on 35 kV overhead lines usually adopts the method of climbing the pole with power outage,which not only takes a long time and has low efficiency,but also reduces power sup-ply reliability.The installation kit for insulation protective covers developed in this paper includes two parts,insulated mounting rod and aluminum mounting alloy,which meets the on-site operating conditions and realizes outage-free installa-tion of insulation protective covers on 35 kV lines.It not only improves disturbance tolerance and power supply reliability of the lines,but also enriches the technical means for live working.The on-site application shows that the kit has high practicality and can greatly improve working efficiency of installing insulation protective covers with a reduction in average time spent by 72.7%.
