The Benefits of Using IEC 60840 Compliant Cables and Accessories for High-Voltage Power Transmission


What is IEC 60840 and why you need it?




If you are involved in any way with high-voltage power transmission, you need to know about IEC 60840. This is an international standard that specifies test methods and requirements for power cable systems, cables alone and accessories alone, for fixed installations and for rated voltages above 30 kV (Um = 36 kV) up to and including 150 kV (Um = 170 kV).

IEC 60840 covers various aspects of power cable systems, such as design, construction, performance, installation, operation, maintenance, testing and certification. It applies to single-core cables and to individually screened three-core cables and to their accessories for usual conditions of installation and operation. It does not apply to special cables, such as submarine cables and their accessories, for which modifications to the standard tests or the setup of special test conditions can be necessary.


Why do you need IEC 60840? Because it ensures that your power cable systems are safe, reliable, efficient and compatible with other components. By following this standard, you can avoid potential hazards such as electric shock, fire, explosion, overheating, short circuit, insulation breakdown, mechanical damage, corrosion or environmental impact. You can also optimize the performance and lifespan of your power cable systems, reduce the risk of failure and downtime, and save on costs and energy consumption.


Moreover, by using IEC 60840 compliant cables and accessories, you can demonstrate your compliance with the international best practices and regulations, and enhance your reputation and credibility in the market. You can also facilitate the trade and interoperability of your products and services across different countries and regions.

What are the main features and changes of IEC 60840:2020?




IEC 60840 is not a static document, but a dynamic one that evolves over time to reflect the changes in technology, market and society. The latest edition of IEC 60840 is IEC 60840:2020, which was published in May 2020. This edition cancels and replaces the previous edition, which was published in 2011. This edition constitutes a technical revision that introduces significant changes with respect to the previous edition. Here are some of them:


Scope and application




Test methods and requirements




The test methods and requirements for power cable systems, cables alone and accessories alone have been revised and updated to reflect the current state of the art and practice. Some of the changes include:



  • Gas immersed cable terminations for use at rated voltages above 52 kV are required to be designed, type and routine tested in accordance with IEC 62271-209 in addition to the routine and type tests specified in this document.



  • Requirements are introduced for composite outdoor termination insulators.



  • The test cylinder diameters specified for the bending test (type and prequalification tests) have been modified in line with IEC TR 61901:2016.



  • A low smoke halogen free oversheath material, designated ST12, is introduced.



  • A test for water penetration in the conductor is added.



  • In addition to tests on the outer protection of joints, type tests on the screen sectionalizing insulation of all accessories have been introduced.



Additional tests under fire conditions




The additional tests under fire conditions that are introduced in IEC 60840:2020 are:



  • Vertical flame spread test, which measures the flame propagation along a vertical cable sample.



  • Smoke density test, which measures the optical density of smoke emitted by a burning cable sample.



  • Acidity and conductivity test, which measures the acidity and conductivity of gases evolved by a burning cable sample.



These tests are applied according to the fire performance declared for the cable. The fire performance classes are defined as follows:
