Abstract

The invention provides a cable tension clamp which comprises a wire clamp body and a pull piece connected to the wire clamp body. The wire clamp body comprises a clamping device which comprises at least two layers of clamping mechanisms, and a fastening structure which removably encircles and fastens a whole body formed by the clamping device and the cable and applies an action force of clamping the cable to the clamping mechanism, wherein at least one cable is clamped between two adjacent layers of clamping mechanisms. The fastening structure can removably encircle and fasten the whole body formed by the clamping device and the cable, in this way, the force of the fastening structure applied to the clamping device is dispersed to the peripheral wall of the clamping device, the clamp looseness of the cable caused by the tilt of two sides of the clamping device under the opposite force of the cable to the two sides of the clamping devices for a long time is prevented, thus the clamping device can maintain the effective and firm clamping of the cable under long-term use.

Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a cable strain clamp. Background technique [0002] Tension clamp is a metal tool mainly used for overhead power lines and for fixing cables on substation towers. When in use, it connects cables to insulator strings, and the insulator strings are connected to iron towers to fix cables and carry loads. The pulling force of the cable and the reduction of the slack of the overhead cable play a very important role in the safe operation of the power system. [0003] An existing patent document with a publication number of CN204633277U discloses a four-core bundled tension clamp, which includes a wedge-shaped pull plate, and the upper and lower sides of the wedge-shaped pull plate are provided with clamping devices for clamping cables. The holding device includes a base and an upper cover set above the base, the clamping device also includes a fastening part that drives the...
