GB/T 32578-2016Railway application -- Fixed installations -- Electric traction overhead contact lines (English PDF)

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the re-drafting method to modify the use of IEC 60913.:2013 "rail transit ground device electric traction overhead contact net".

There are technical differences between this standard and IEC 60913.:2013, and the terms involved in these differences have been passed through the margin the vertical single line (|) is marked, and Appendix F gives a list of the corresponding technical differences and their causes.

This standard has made the following editorial changes.

- Amend the order of paragraph 1 of chapter 1 to adjust paragraph 1 of IEC 60913.:2013 to paragraph 1;

- Added sections 3.7.1 and 3.7.2 to classify acronyms and symbols;

--- modify the location of Figure 1, from 5.10.7 to 5.10.4, due to 5.10.4 for the first time;

--- modify the 8.15.3 voltage requirements described by the way, the clear implementation of GB/T 1402;

- modified part of the reference to the corresponding national standards and changed to normative reference documents;

- deleted references that did not appear in the text;

--- Added Appendix F to illustrate technical differences and their causes.

1 Scope

This standard specifies the requirements and tests for the design of the catenary system, the structural components and their structural calculations and inspections, the design of the assembly, and Requirements and tests for individual component design.

This standard applies to electric traction catenary systems for railway and urban rail transit systems (including trolley buses).

This standard applies to the new catenary system, as well as the existing catenary system of the overall renovation.

This standard does not apply to contact rail systems located next to the rail.
