This standard was drafted. Xi'an High Voltage Apparatus Research Institute Co., Ltd. The main drafters of this standard. Yun-Peng Wang, Ding Jingling. Groove connection dimensions of string insulator1 ScopeThe purpose of this standard is to provide a series of groove connection size, so insulators and accessories provided by different manufacturers can be interchanged. Note 1. GB/T 7253-2005 "nominal voltage above 1000V AC system overhead line insulators porcelain or glass insulators Disc Suspension elements Characteristics of insulator elements "provides with a standard size and strength of level 1 between tables. IEC 60433 "long rod insulator string element characteristics" put Table for 2 with standard size and strength between the grades. Note 2. If the table size 1 provided is not met, then the recommended 25mm, 28mm and 32mm connecting pin, which pins can be used to connect a high intensity Grade (see GB/T 7253-2005 Notes to Table 2). This standard applies to pin type insulators and long rod string components, and accessories used in conjunction with these insulators.2 Normative referencesThe following documents for the application of this document is essential.
