Spacer dampers, type РД

OTL wires and conductors are subject to the oscillations caused by wind. Vibration and oscillations cause wear and deterioration of wires, line accessories, suspension strings, while wire dancing leads to the tower failure. An effective solution of a wire vibration problem in subspans is using spacer dampers.

The number of beams in the spacer damper is equal to the number of OTL bundle conductor wires and ensures the required distance between them, absorbing of vibration and different types of oscillations, and prevention of wire dancing.

Spacer dampers, type РД, 3РД, 4РД are intended for holding two, three, four wires of the bundle phase conductors of outdoor switchyard in a spaced relationship, and also for lowering suboscillations level of wires in the subspans. Spacer dampers, РД, 3РД, 4РД meet the requirements of TU U 31.2-30255335-002: 2006.
