Types of Dampers in Transmission Lines

Common potentiometer types

Vibration Dampers: This type of damper is usually used to reduce the vibration of wire lines caused by wind vibration or natural vibration of wires. They can reduce the swing amplitude of the wire and prevent the vibration of the gap from causing damage to the wire and bracket structure.

Dead-end Dampers: Dead-end dampers are installed at the end of the output line and are mainly used to reduce the termination vibration of the conductor. They help stabilize the termination position of the conductors and prevent bending of the conductors or vibration of the strands in wind or other vibrating conditions.

Stockbridge Damper: Stockbridge Damper is installed on the transmission line tower or on the conductor when it is spanned. It is used to prevent the gravity phenomenon of long-span conductors during wind vibration. They adjust the vibration frequency and reduce the impact of vibration by suspending weights at the wire terminals.

Balance Dampers: Balance dampers are used to balance the vibration tension of wires across lines to prevent excessive vibration or damage to wires under wind or other vibration conditions.

Summary

These dampers play a key role in the output circuit, helping to reduce the impact of vibration on equipment and structures and improving the stability and reliability of the circuit.
