This International Standard is applicable to polymeric insulators for a.c. systems with a nominal voltage greater than 1 000 V (frequency less than 100 Hz) and d.c. systems with a nominal voltage greater than 1 500 V whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard are intended for use both on HV overhead lines and in substations, in both indoor and outdoor applications. They include solid core, hollow core and resin insulators. Hybrid insulators with ceramic core and polymeric housing are included, while coated insulators (e.g. with RTV silicone rubber coatings) are not included in this standard.
