ABSTRACT:
A device for reducing a shock load having a longitudinal direction along a power line coupled through an insulator to a crossarm of a transmission tower, comprising: a rotary damper coupled between the insulator and the crossarm for rotating by the insulator in the longitudinal direction in response to the shock load, the damper having an axle to which the insulator is rotatably coupled; and, a torsion bar coupled at a first end to the axle and at a second end to the crossarm for resisting rotation of the insulator, whereby at least a portion of the shock load is absorbed.
