Aimed at the conditions of countryside low-voltage power distribution network with low power factor, to adopt on-pole reactive compensation device in completing and rebuilding of agricultural power network, so as to reduce low-voltage line reactive current transmission, to reduce line voltage loss, to raise power factor.

Combining with the actual operating condition of the line,isolating tray for upward-formed pole in 110kV line is made,therefore the maintenance level and operational ability for transmission line are improved greatly.
