Application Summary AI generated
This standard specifies the construction, dimensions, and test requirements for power cables with extruded insulation rated at 35 kV (up to 40.5 kV maximum). It is applied in electrical power distribution networks, substations, and industrial installations where medium-voltage cables are used for transmitting electricity from transformers to switchgear or large equipment. The standard ensures cable performance under high-voltage stress, including partial discharge and dielectric tests, for safe and reliable operation in utility and heavy industrial contexts.
