Preformed Dampers

Preformed Dampers

Preformed Dampers can be installed quickly and conveniently by hands without any tools. The grip strength is distributed evenly within 60cm area of Preformed Rods and conductor, and it avoids stress concentration of conductors. The excellent performance of aluminum clad steel installation with Preformed Rods ensure the sustained stable and reliable grip strength between Preformed Rods and Conductor.

Traditional Dampers are installed with torque wrench, and fixed with bolt, it can cause the torque too bigger or smaller. It can cause damage of conductions and bolts by too bigger torque, Contrarily, the grip strength of Vibration Damper and conductor can’t meet the requirement by too smaller torque. Even the grip strength of Vibration Damper and conductor can meet the requirement by being installed with torque wrench. With the vibration between Vibration Damper and conductor during the line operation, the stress of Vibration Damper and bolt get loose, the grip strength of Vibration Damper and conductor will decrease, it can also cause the Vibration Damper loose. 

Preformed Dampers solve the shortage of traditional Vibration Damper. Preformed Dampers can be installed quickly and conveniently by hands without any tools. The grip strength is distributed evenly within 60cm area of Preformed Rods and conductor, and it avoids stress concentration of conductors. The excellent performance of aluminum clad steel installation with Preformed Rods ensure the sustained stable and reliable grip strength between Preformed Rods and Conductor. 

Preformed Dampers has four frequency with tuning fork structure of Damper Weight, it can cover the vibration frequency range of conductors and ground wires. Damper Weight stuck with Messenger Wires enduringly can bear the machine load under installation, maintain and operation condition. Special appearance design can prevent icing and ponding. The Preformed Vibration Damper can’t damage the conductors and ground wires by installation convenience and safety. The Preformed Dampers are designed to resist corona.

 Direction: 

 

1. Calculate the installation distance, the distance between the end of Vibration Damper and Amour Rods must be more than 70mm. 

2.The big Damper Weight of low frequency is close to pole or tower  

3. The quantity of damper per span length is according to cable , span length and topography. The normal specification is as follows:
