The utility model discloses a short circuit diverging device for the current division at the strain insulator drainage plate both ends on the transmission pressure, it includes two fasteners of being made and passed through wire electric connection by metal material, the fastener has the double -layered line hole with transmission pressure diameter looks adaptation, and two fastener centre grippings are at the both ends of strain insulator drainage plate. The beneficial effect of the utility model: two fasteners are fixed at the both ends of strain insulator drainage plate, have realized short circuit diverging device and the reliable of transmission pressure and have been connected, and can ensure the ability of overflowing to satisfy live working's needs, further reach the purpose of fast overhaul, processing. In addition, through setting up the regulation pole of taking the rating nut to the aperture of realizing clamp line hole is adjustable, is suitable for the not transmission pressure in collinear footpath in order to realize the device.
