GB/T 7253-2019 Insulators for overhead lines with a nominal voltage above 1 000 V—Ceramic or glass insulator units for a.c.systems—Characteristics of insulator units of the cap and pin type
Abstract
This standard specifies the main mechanical characteristics and key dimensions of disc-shaped suspension insulator string components.
This standard applies to disc-shaped suspension insulator string components used in AC overhead lines with a nominal voltage of more than 1,000 V and a frequency of no more than 100 Hz, where the insulators are made of porcelain or glass. These insulator string components have a ball-and-socket connection or groove connection. It also applies to similar-structured insulators used in substations.
