GB/T 18135-2008Electrotechnical engineering drawings rules of CAD (English PDF)

Foreword

This standard replaces GB/T 18135-2000, and GB/T 18135-2000, compared with the following changes.

--- Reference GB/T 6988.1-2008, modify the electrical drawing corresponding technical documentation requirements;

--- "Definitions" chapter to "Terms and Definitions", by deleting specific terms and definitions;

--- Increased from Electrical Drawing identification system. the reference code, the terminal code, signal code, file code, such as identification requirements;

--- Increased charts, tables maps, tables used in CAD systems;

--- Proposed software selection requirements.

1 Scope

This standard specifies the general rules of electrical engineering CAD drawings.

This standard applies to the preparation of diagrams using CAD technology (including schematic diagram, function diagram, schematics, wiring diagrams, etc.), images (such as cloth FIG set), table maps, tables and other electrical technical documents.
