Trends & Lessons from Laboratory Testing of Power Cables

Analysis of all type tests performed at KEMA Labs over decades shows that 1 out of 4 type tests initially fails to meet the requirements specified in the standards. Moreover, this initial failure rate has unexpectedly remained stable over decades in spite of improvements in materials, calculation methods and production technologies. Maintaining a low in-service failure rate, type-testing and independent certification remains a key ‘de-risk tool’ to distinguish well-designed, well-manufactured products from those that are inferior. This presentation looks at existing standards for AC cable systems and reviews historical data and trends on failures during type testing of cables, joints and terminations.
