Spacer Damper FD Serie
Adopting a preform structure, the clamping strength between the preform installation damper and the conductor is evenly distributed at a distance of 30-60cm in the length area. It can effectively protect conductors and avoid conductor stress concentration.
FD series interval damper uses the rotation and swing of the hammers at both ends to generate the rated frictional damping force, so that the galvanized iron wire strands slide against each other and consume swing energy.
Stockbridge Damper Instructions/Descrption
Common anti-vibration methods include installing Stockbridge dampers, damper wires, or a combination of Stockbridge dampers and damper wires. High-frequency vibrations are mainly damped by damping wires, and low-frequency vibrations are mainly damped by anti-vibration dampers. Due to the small span and the low suspension point of the wire, the ordinary span wire generally uses an anti-vibration hammer to prevent vibration. When vibrating, the wire drives the anti-vibration hammer to vibrate together, and the vibration energy of the wire is absorbed by the anti-vibration hammer, thereby protecting the anti-vibration and anti-vibration of the transmission line wire.
Due to the long vibration time under strong wind conditions, it is required to limit the amplitude to a low level, and the amplitude should not exceed 50% of the normal gear. Generally, a combination of damping wire and shock absorber is used. In addition, in some areas where wind vibration conditions are particularly severe, Stockbridge dampers cannot meet the requirements, and damping wires and Stockbridge dampers must be used to suppress wind vibration.
