The main clamp plate and the clamp cover plate are connected and fastened by clamp fastening bolts. A hanging plate is connected to the upper end of the jumper wire clamp main plate. The flow wire clamp is welded by an upper part of a flow wire pipe and a lower half of a flow wire clamp terminal plate. The flow wire clamp terminal plate and the jumper wire clamp terminal plate are connected and fastened by terminal plate fastening bolts.

[0006] Further, the hanging plate is in the shape of an ear plate, and a pair of first reinforcing ribs are symmetrically connected to the outer side of the hanging plate. A second reinforcing rib is connected to the center of the inner side of the hanging plate.

[0007] Further, the jumper wire clamp main plate and the clamp cover plate are made of aluminum material in one piece, and a semicircular groove is formed in the inner part of each of the main clamp plate and the clamp cover plate. After being connected and fastened, the two semicircular grooves form a circular groove for clamping jumper.

[0008] Further, the drain wire clamp and the drain wire clamp terminal plate are integrally made of aluminum material, and the drain wire clamp is internally provided with a drain wire.

[0009] Further, the jumper wire insulator string body comprises an insulator string, and a rectangular joint plate is arranged at the lower end of the insulator string.

[0010] Further, a voltage-sharing shielding ring is symmetrically arranged at the left and right sides of the rectangular joint plate.

[0011] The jumper wire insulator string uses the suspension type T-shaped wire clamp, which is different from the conventional T-shaped wire clamp. BRIEF DESCRIPTION OF DRAWINGS
