Product Description

China Cross Type Spacer Damper

Description:
Spacer dampers are originally developed to suppress bundle conductor subspan oscillations that could cause damage to the multi-conductor bundle systems. Later, it was determined that they could be used to control aeolian vibration as well as wake-induced oscillation. The spacer damper is designed to maintain the original geometry of the bundle system against loads. It must also restore the bundle to normal posture after experiencing severe loads due to short-circuit currents, ice and wind.
The Cross Type Spacer Dampers has the function of a spacer in maintaining conductor separation and the function of a damper in controlling aeolian vibration and oscillation.
