This standard specifies the naming principles, composition and preparation methods of insulator (including bushing) product models. This standard applies to the following high-voltage insulators for systems with nominal voltages higher than 1000V;
——Disk-shaped suspended porcelain or glass insulator string components;
——Rod-shaped suspended composite insulators;
——Long rod-shaped porcelain insulator string components;
——Line post insulators;
——Line pin porcelain insulators;
——Insulators for ground wires of overhead transmission lines;
——Rod post insulators;
——Hollow insulators;
——Bushings.
