IEC 62067:2011 PDF (Not Available)

IEC 62067:2011 is a standard that outlines test methods and requirements for power cables with extruded insulation and their accessories. It specifically applies to installations with rated voltages above 150 kV up to 500 kV. The standard focuses on single-core cables and their accessories, outlining requirements for normal installation and operation conditions.

It should be noted that this standard does not cover special cables and their accessories, such as submarine cables, which may require modifications to the standard tests or special test conditions. Additionally, the standard does not address transition joints between cables with extruded insulation and paper insulated cables.

The significant technical changes in this edition of the standard include the addition of an extension to the prequalification test, reducing the required time for completion. It also revises the sensitivity level for the partial discharge test during routine tests on the main insulation of prefabricated accessories, reducing it from 10 pC to 5 pC.
