Introduction

"Importers and high-voltage electrical testing procedures - Part 2. High-voltage porcelain insulators," the import and export of high-voltage porcelain insulators inspection work based on the Import and export of high-voltage porcelain insulators play a guiding and regulating inspection. With China's accession to the World Trade Organization (WTO) and the revised "People's Republic of China Import and Export Commodity Inspection Law" Import and Export Commodity Inspection Test mode has undergone great changes, and changes in order to adapt to the situation, the national exit inspection and quarantine departments in charge of the establishment of immigration check Inspection and quarantine industry-standard system. This part belongs to industry-standard system of inspection and quarantine fourth floor --- personality standard porcelain insulators for high voltage characteristics, provides for import and export Particular requirements for high-voltage porcelain insulators inspection. High-voltage electrical inspection of import and export Part 2. High Voltage Insulators

1 Scope

This section provides the import and export of high-voltage porcelain insulators sampling, testing and the results of determination. This section applies to the rated voltage 1000V and above, no more than 100Hz frequency of import and export overhead power lines, electrical installations and Test equipment used on porcelain insulators. This section applies to the following seven types of high-voltage porcelain insulators products inspection. --- Disc Suspension porcelain insulators; --- High-voltage line pin porcelain insulators; --- High voltage line butterfly porcelain insulators; --- Tension overhead power lines with porcelain insulators; --- High-voltage line post porcelain insulators; --- High voltage post insulators; --- 110kV and 220kV outdoor less oil circuit breakers porcelain sets. Other types of porcelain insulators can refer to the use of this section. This section does not apply to the insulator under test conditions damage the insulating member and metal accessories used.
