GB/T 11030-2008Characteristics of rod ceramic insulators for a.c. contact system of electrified railways (English PDF)

Foreword

This standard replaces GB 11030-2000 "ac traction lines with porcelain insulators Rod" in size and features section. This standard compared with GB 11030-2000 in the size and nature of the content main changes are as follows:

--- Increasing the mechanical failing load 12kN and 16kN level two varieties, delete the tunnel with hanging and positioning of two formula Species;

--- Creepage distances former 1000mm, 1200mm and 1500mm three kinds of change 1200mm, 1400mm and 1600mm Three kinds;

--- Remove the original standard in Appendix A "method of measuring the quality and appearance of the glaze layer semiconductor resistance" content added "Insulators cantilever Jack location of the pin "content;

--- Remove the original standard Appendix B "transitional insulator main dimensions and characteristics of the" content, increase the "old model, said insulator party Law "content. This standard should be GB/T 1001.1-2003 "nominal high voltage overhead line insulators above 1000V - Part 1. System AC Ceramic or glass insulator element definitions, test methods and acceptance criteria "used in conjunction. Appendix A of this standard and Appendix B is an informative annex. The standard proposed by China Electrical Equipment Industrial Association. This standard by the National Standardization Technical Committee Insulators (SAC/TC80) centralized. This standard was drafted. Xi'an Institute of Electric Porcelain, Third Railway Survey and Design Institute, Suzhou Cichang like. The main drafters of this standard. Dingjing Ling, Guo Wei Gong, Lu Chau. This standard replaces the standards previously issued as follows:

--- GB 11030-1989, GB 11030-2000. Exchange of electrified railway catenary with Rod porcelain insulators Characteristics

1 Scope

GB/T 11030-2008 is the Chinese national standard on characteristics of rod ceramic insulators for a.c. contact system of electrified railways, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 June 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 April 2009. Classification: ICS 29.080.10, CCS K48. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard applies to nominal voltage of 25kV, AC single-phase power frequency electric railway catenary Rod porcelain insulators (hereinafter referred to as absolute Edge sub). This standard applies to light-polluted area, heavy polluted area and high altitudes catenary cantilever supporting insulators. This standard specifies the characteristics of electrical insulators, mechanical properties and dimensional characteristics (see Table 1). This standard also specifies the insulator model and methods of marking.

Note 1. A general definition, test method GB/T 1001.1-2003 in.

Note 2. GB/T 1001.1-2003, the term "electric traction lines" with this standard, the term "railway electrification" has the same meaning.
