The LKP 70/20-I(IG) type polymeric suspension line insulators are designed to protect birds from electric shock upon contact with the insulator. Additionally, their use prevents power line (PL) outages due to electrical flashovers caused by birds or contaminants flowing onto the insulators from the crossarm. The application of these insulators eliminates the need for additional bird protection devices. Similar to LK-type insulators, these insulators are intended for fastening and insulating uninsulated PL conductors of 10–35 kV AC with a frequency up to 100 Hz at ambient temperatures ranging from -60 to +50 °C. The climatic version and placement category comply with UHL 1 according to GOST 15150. The insulators are manufactured according to TU 3494-005-57966314-2006 and meet the standards of GOST 28856, GOST R 55189, and IEC 61109.
