Who has counted the standard documents related to electricity in our chemical (petroleum and petrochemical) industry? Please summarize it here for easy reference. First, I’ll list a few: 1. HG/T 20686-1990 – Unified Regulations on Graphic and Text Symbols for Electrical Design in Chemical Enterprises; 2. SH 3038-2000 – Technical Specifications for Electrical Design of Production Units in Petrochemical Enterprises; 3. HG 20551-1993 – Common Calculation Rules for Electrical Design in Chemical Plants. Please feel free to add more, following my numbering sequence.
