Abstract

This utility model provides a power fitting for transmission line towers, belonging to the field of power equipment technology. The power fitting for transmission line towers includes a clamping body, a pressing device, a suspension ring, and an adjusting mechanism. The clamping body has a U-shaped structure, with a conductor receiving groove at its open end. The inner surface of the conductor receiving groove has an anti-slip texture. The pressing device includes a pressing plate and a fastening bolt. The pressing plate is threadedly connected to the open end of the clamping body via the fastening bolt, which passes through threaded holes on both sides of the clamping body. The inner surface of the pressing plate matches the shape of the conductor receiving groove. The suspension ring is located at the top of the clamping body and is rotatably connected to the top pin hole of the clamping body via a pin shaft. The axis of the suspension ring is perpendicular to the axis of the clamping body. This utility model can solve the technical problem of unstable conductor clamping in power fittings for transmission line towers.
