There is no extra physical strain put on the conductor or structures. 3.8 cm X 3.8 cm wooden handle. The roller assembly is placed on the conductor by a lineman up the pole or tower -one roller per conductor. The roller wheel assembly is made of aluminum for lightness as well as for softness to reduce conductor and insulator damage. The wheel of the roller moving over the ice plus the bend in the conductor caused by the pull on the rope causes the ice to fracture and fall off.
Transmission lines are de-energized before rolling starts.
Distribution lines up to 12 kV can be rolled while energized with no modification to sticks. 25 kV distribution lines can be rolled while energized by installing an insulated link in the stick handle. Ice Rolling -Advantages Not restricted by temperature or wind. Can be initiated at a local level. Sky wires can be rolled.
