ABSTRACT:
The power line support of the present invention comprises a support tower having a lower end supported on the ground and having an upper end. A power line energy absorber is attached to the upper end of the support tower and comprises a housing attached to the support tower, a reciprocating piston within the housing and pneumatic damping chambers within the housing on opposite sides of the piston for yieldably resisting reciprocating movement of the piston within the housing. A cable is connected to the piston and extends over a pulley downwardly to the electrical insulator which connects to the power line where it supports the power line above the ground. Dynamic energy from the power line is transferred upwardly through the cable to the piston and is absorbed by virtue of the compression and expansion of the air within the chambers on opposite sides of the piston.
