GB/T 1000-2016Dimensions and characteristics of pin insulators of ceramic for high-voltage overhead lines (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard instead of GB/T 1000.2-1988 "high voltage line pin porcelain insulator size and characteristics", and GB/T 1000.2-1988 phase In addition to editorial changes, the main technical changes are as follows:

--- As the original standard GB/T 1000.1 has been incorporated into the GB/T 1001.1, and was replaced, therefore, the revision of the standard number to modify;

--- the original standard in the "technical requirements" of the content, respectively, into Chapter 4, Chapter 5, Chapter 6; - the form of "purpose and scope" of Chapter 1 has been changed;

--- Chapter 2, "normative reference documents" in the modified and added; In Chapter 3, "Terminology and Definitions", the term "bending failure of porcelain pieces" was added;

--- the "model" part into Chapter 4. structure type and model, according to JB/T 9683-2012 "insulator product model compilers Law "in the

5.5 pairs of needle insulator product model preparation method, in Table 1 and Table 2 on the insulator model was re- Prepared and compared with the original model (see Appendix A);

--- put the table in Table 2 into the table;

--- the original standard of

4.4 to Chapter 6, and the "zinc sleeve thread connection insulator steel feet screw size" to "steel feet connecting thread Size ", see Chapter 6 of the chapter title;

--- Because GB/T 1000.1 has been replaced by GB/T 1001.1, the text of the "Dimensional Tolerance" section in Chapter 6 makes the phase Should change;

--- According to the current domestic high-voltage line needle porcelain insulator products increased by two product types shown in Figure 2, Figure 7, an increase of three Specifications of the product, its size and characteristics shown in Table 1 and Table 2; - Added Appendix A (normative) and Appendix B (informative).

1 Scope

GB/T 1000-2016 is the Chinese national standard on dimensions and characteristics of pin insulators of ceramic for high-voltage overhead lines, 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 25 April 2016 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 November 2016. 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 specifies the structure type, size, mechanical characteristics and electrical characteristics of high voltage line needle porcelain insulators. This standard applies to the nominal voltage of 10kV and below, the frequency is not higher than 100Hz AC overhead power line with the needle (Hereinafter referred to as insulator). Insulator installation location for the ambient temperature of -40 °C ~ 40 °C, the altitude of not more than 1000m area. This standard does not apply to insulators used in environments where insulator porcelain pieces, metal attachments are severely corroded or the insulator performance is reduced.
