MRJ3 Three-split Spacer Damper

Spacers for Three-Bundle Conductor Type MRJ3

The spacer damper is a device that is installed in bundled conductors to maintain a fixed distance between each conductor, preventing collisions and reducing vibration caused by the wind. Typically, the spacer damper is installed at a distance of 50-60m in the middle of the span. There are different types of spacer dampers, including two split, four split, six split, and eight split. When compared to bundled conductors without spacer dampers, the two split type reduces vibration amplitude by 50%, while the four split type reduces it by 87% or 90%.

Function

1. Maintain A Safe Distance Between Conductors

The conductor spacer bar can ensure that the conductors maintain a certain safety distance between the conductors, to avoid mutual contact or short circuit between the conductors, to prevent the power system from failing.

2. Prevent Excessive Conductor Sagging

conductor spacer can limit the arc of the conductor, that is, the conductor across a large distance, due to their own gravity and external wind and other factors, the conductor will produce a certain arc sag. Excessive arc sag will cause the conductor to contact with other facilities or the ground, increasing the risk of short circuits and electrocution, while the conductor spacer bar can limit the arc sag of the conductor and maintain the safe height of the conductor.

3. Separating Conductors

In the power system, there may be more than one conductor at the same time using the same bracket or suspension rod, in order to maintain a safe distance between the conductors, to prevent each other from interfering with the use of conductor spacer bars to separate the conductors.

Technical And Requirements

The main technical requirement for spacer damper is that the clamp must have enough grip strength,no looseness in long service and have to bear the centripetal force and fatigue under long - term vibration of split conductors in short circuit.
