A side tie is a structural device used to provide extra support and stability to the conductor or wire on the transmission line. It installs horizontally between the main supporting structure and the conductor themselves. It also prevents galloping caused by wind or other environmental factors. A side tie is from materials such as steel cables or rods. They help to withstand mechanical stresses and environmental conditions that transmission lines experience. Corrosion-resistant side ties can withstand the coastal environments of Southeast Asia. Common types include spacer dampers, Stockbridge dampers, dead-ends and vibration dampers. They find help in maintaining conductor spacing, reducing conductor vibration, enhancing structural integrity and supporting line insulators.
