This Part is Part 3 of GB/T 5023.This Part equivalently adopts IEC 60227-3.1997 Polyvinyl Chloride Insulated Cables of Rated Voltages up to and Including 450/750V – Part 3.Non-Sheathed Cables for Fixed Wiring, Version 2.1 (English Edition). For ease of use, this Part of GB/T 5023 makes the following editorial changes. --- Use “decimal point” to replace the “comma” that acts as the decimal point --- Delete the Foreword of IEC 60227-3.1997. This Part replaces GB 5023.3-1997 Polyvinyl Chloride Insulated Cables of Rated Voltages up to and Including 450/750V. Compared with GB 5023.3-1997, this Part mainly has the following changes. --- Regulate the upper- and lower-limit against the overall diameter of 60227 IEC Model 01, 02, 05, 06, 07, 08, and other types of cables; adjust the upper limit of diameter of cables in the original standard (Table 1, 3, 5, 7, 9, 11); --- Modify 60227 IEC Model 01-type cable’s 35mm2 and 50mm2 minimum insulation resistance; 35mm2 corresponding minimum insulation resistance of 0.0040 MΩ•km was changed into 0.0043 MΩ•km; while 50mm2 corresponding minimum insulation resistance of 0.0045 MΩ•km was changed into 0.0043 MΩ•km. This Part was proposed by China Electrical Equipment Industrial Association.
