Reliability Improvement for 35 kV Overhead Ground Wire Replacement
The maintenance of 35 kV line usually lasts a long time; therefore,this paper analyzes the causes,including the long 35 kV line,dispersed construction sites,as well as heavy worrk load.A new type of connection tool has been developed to draw the old and new wires,thereby shortening the overhead ground wire replacement time,improving the efficiency of route maintenance,finally shortening the time of 35 kV line overhaul.The maintenance time is controlled within 200 minutes at a time,further improving the power supply reliability.
