The ZPK series devices are designed to protect insulators from contamination by bird droppings and to prevent birds from electric shock on overhead power lines (OHL) due to flashovers caused by droppings. They are installed on the OHL crossarm above the attachment point of a polymer insulator or a string of glass insulators, preventing birds from perching in the protected area. Additionally, they have a deterrent effect due to oscillations caused by wind.
