The International Electrotechnical Commission (IEC) has published the updated standard IEC 60287:2024 SER, which addresses the thermal evaluation of cables and cable systems for electric power installations. This standard was revised on January 8, 2018, to provide more accurate guidelines for assessing the temperature limits that should be applied to individual parts of a cable during operation under normal conditions. It includes detailed information on how to calculate permissible current ratings based on various environmental factors such as ambient air temperatures, soil thermal resistivity, and installation methods.
The IEC 60287:2024 SER provides critical safety guidelines for the design, manufacture, and use of cables in electrical power systems. It ensures that cables can operate safely under different load conditions while maintaining their mechanical integrity over time. The standard is widely recognized by manufacturers, testing laboratories, and regulatory bodies around the world as a benchmark for cable quality and performance.
Key aspects covered in this revision include enhanced thermal resistance calculations for various types of insulation materials commonly used in electrical cables. Additionally, it offers updated guidance on assessing load effects, conductor heating, and temperature rise analysis to ensure compliance with international safety standards.
