Usage
A pulley support is different from a suspension or anchor attachment. With an appropriate mechanical tension, the line/cable is hold by a vertical accessory and maintained at a proper distance of the support without any clamp to fit them. The cable can move and the support is designed to follow it with a moving part (mandatory). The usual groove wheel for such pulleys can be replaced by an appropriate insulator in case of bare power conductors. A pulley on which the line is terminating is an actual anchor and shouldn't be confused with this value.

Wood post insulators supports live wires of electric fences. This support is designed to allow movement of the live wire. This is an actual pulley and not a suspension one. |
