This guide is based on utility field experiences, results of Research Lab tests, and manufacturers' recommendations. the guide deals with composite insulators, which include a core, weather sheds and metal end fittings. The core consists of resin and axially aligned glass fibers. The weather sheds are of polymeric materials.
This guide specifies the technical requirements for overhead transmission lines with composite insulated crossarm (CICA) support, which include design requirements, component technology, test technology, construction and acceptance, and operation and maintenance specifications.
