Abstract
An universal support saddle for replacing insulator strings of a tangent tower and a suspension angle tower in a 500kV circuit on an electrified condition is formed by assembling a lead screw clamping seat, a principle profile fixing groove, a support saddle assembly hole, a principle profile fixing screw rod, a principle profile fixing screw rod locking nail and a hoisting rod connecting hole, wherein thread grooves and screw caps corresponding to each other and both capable of enhancing friction are arranged on a connecting panel between the principle profile fixing screw rod locking nail and the universal support saddle.
