Scope
The purpose of this standard is to provide the ampacity for a reasonable life of conductors and insulation, under normal operating conditions, subject to the heating effects produced during the duration of the current flow. Electric shock protection (see GB 14821.1), thermal effect protection (see GB 16895.2), overcurrent protection (see GB 16895.5), voltage drop (see GB 16895.6 Article 525) and Temperature limit on the terminals of wire-connected equipment (GB 16895.6 Article 526). At present, this standard only applies to unarmored cables and insulated conductors with a rated voltage not exceeding AC 1 kV or DC 1.5 kV, and does not apply to armored single-core cables. Note: For single-core armored cables, the ampacity given in this standard needs to be multiplied by an appropriate reduction factor. This issue should be discussed by the cable manufacturer, and this solution is also applicable to the ampacity of single-core unarmored cables passing through metal conduits (see Article 521.5 of GB l6895.6).
