 The biggest core advantage of needle insulators is their simple structure, low cost, and easy installation, making them the absolute mainstay of straight and small angle poles in medium and low voltage distribution networks (especially 10kV and below). Its high reliability and maintenance free characteristics in clean environments are also the cornerstone of its widespread application. Although limited in high voltage, heavy pollution and other environments, needle insulators still play an irreplaceable and important role within their scope of application due to their excellent economy and practicality.
