The utility model provides an extra -high voltage transformer substation makes somebody a mere figurehead generating line conductor spacer installing the system, including the pulling equipment, corner block, traction cable, ropeway carrying -rope, be used for adjusting chain block, the bearing coaster that is used for supporting the traction cable when pulling that the ropeway carrying -rope arc hangs down, install on extra -high voltage transformer substation framework and be used for installing the bearing coaster and connect the ropeway carrying -rope the fastening means, can pull electronic manned driving. The utility model discloses not only can solve the characteristics that conventional electronic driving climbing capability is not enough, the more electronic driving of efficiency wants high moreover. Constructor takes and can pull electronic manned driving and reach the appointed place and carry out conductor spacer installation, assurance construction quality that can be fine, the conductor spacer problem of installing when the built on stilts generating line of very economic solution 1000kV extra -high voltage transformer substation be expanded conductor.
