Scope
This standard specifies the definition, test methods, and acceptance criteria for rod-shaped suspension hard composite insulators used in overhead lines of AC systems with a nominal voltage of more than 1000V. This standard applies to hard composite insulators (hereinafter referred to as insulators) used in overhead lines and substations with a nominal voltage of more than 1000V for suspension and tensioning purposes. The insulators consist of an insulating core rod, a bushing, and end fittings. The load-bearing core rod is made of resin-impregnated glass fiber, and the end fittings are permanently installed on the insulating core rod. The bushing is made of hard composite material.
