Scope
This standard specifies the technical requirements and test methods for hollow inflatable line-pole composite insulators (hereinafter referred to as insulators) used in 1000kV AC overhead transmission lines. This standard applies to areas with an altitude of no more than 1000m and an ambient temperature between -40°C and 40°C. Hollow inflatable line-pole composite insulators consist of an insulating core, a jacket, and end attachments. The insulating core is used to withstand loads and is composed of an insulating tube and an insulating gas (nitrogen with an absolute gas pressure of no less than 0.35MPa). The insulating tube is made of epoxy resin-impregnated glass fiber, and the jacket is made of high-temperature vulcanized silicone rubber. The end attachments are permanently fixed to the insulating core.
