CU POLY OVERHEAD
Copper Transformer Riser Wire. Black Polyethylene Covered. Solid or Stranded Soft Drawn Copper Conductor.
Application
Used on transformers as connection between line conductor and transformer primary bushing in applications where protection from momentary contact from wildlife is needed. Although not treated as an insulation, the covering on transformer riser wire does provide an increased level of protection from momentary grounded contacts caused by wildlife, excessive wind and tree limbs or other grounded objects in the proximity of the high voltage lead. May be used on distribution system voltages up to 35kV line-to-line.
