Suspended Bearings are unstable and require for the operability control means such as rapidly acting feedback control systems to compensate for displacements from the set point. Suspended bearings are developed as an alternative to air bearings. Suspended bearings enable flywheels to attain a speed of 10000 revolutions per minute.
Suspension clamps have the axis of oscillation in the plane of the axis of the conductor. These are to be used for both phase conductors and shield wires as well as for straight line and angle supports. These are capable of being fitted with counter weights. It can be able to withstand the mechanical stresses, which can occur during transport, handling, and installation at temperatures as low as -40° C.
