Polymer rod post insulator IPRP-8-220/950-А is to be used for insulation and protection of current-carrying units in electric devices, electricity distribution plants, switch substations with 220 kV voltage as rotary insulating element, supporting conductor lines and «knives» of outside plant disconnectors, and as a part of bus rod support.
Polymer insulator IPRP-8-220/950-А is a modern alternative to traditional ceramic and porcelain insulators.
