Abstract
The utility model provides a plug-wedge combined type strain clamp which is used in a strain conductor, a corner conductor and a terminal clamping conductor of a high voltage transmission line, wherein the inside of the strain clamp is provided with a clamp seat of a tapered clamp through hole, a wedge group and a U-shaped screw group arranged inside the tapered clamp through hole to clamp a transmission line and a hook movably arranged on the hollow clamp seat. The utility model is suitable to be used in a conductor with a large cross-sectional area of a 60KV to 1,200 KV high voltage transmission line; when the strain clamp is adopted, a conductor of a strain tower only has one terminal (the prior conductor has at least two terminals), thereby substantially increasing the transmission power of a transmission line; moreover, a clamp crimp connection machine set is no longer used during installing the strain clamp, which greatly improves the convenience during installation.
