How Do Wedge-type Tension Clamps Achieve Low-loss Transmission?

The contact resistance of fixed devices in power transmission lines directly affects the efficiency of power transmission. dead end loop clamp Through a special mechanical structure design, it maintains extremely low resistance while withstanding conductor tension, a characteristic that prevents significant power loss in long-distance transmission projects.

dead end tension clamp A clamping method using conical wedges that engage with the conductor is employed. When the conductor is under tension, the wedges automatically tighten along the conical groove. This self-locking mechanism creates a large-area metal-to-metal contact between the wedges and the conductor, with contact pressure increasing with tension. The ample contact area disperses the current density, reducing the current intensity per unit area and consequently decreasing Joule heating.

fiber optic dead end clamp The main body and wedges are typically made of aluminum or copper alloy, with conductivity close to that of overhead conductor materials. Metal connections of the same material do not create a significant potential difference, and the impedance encountered by current passing through the connection is essentially the same as that of the conductor itself. The material surface is polished to remove oxide layers and burrs, resulting in smoother electron transport paths between the metal lattices.
