Includes the oil-immersed single-phase connection assemblies of cables for transformers and reactors designed in accordance with EN 60076 series.

This European Standard covers the oil-immersed single-phase connection assemblies of cables for transformers and reactors designed in accordance with EN60076 series. NOTE The term \'transformer\' is used as common definition for transformer and reactor. If no separate cable connection box is used and dry-type cable terminations are directly installed into the transformer tank the requirements of this standard should be followed. The purpose of EN50299‑2 is to establish for the cable connection assemblies: electrical and mechanical requirements including interchangeability; limits of supply; tests to be carried out. It complements and amends, if necessary, the relevant standards and applies to dry-type cable terminations for power cables with extruded insulation which may be used with similar interfaces for the cable entrance in switchgear applications according to EN62271‑209 . This standard applies to oil-filled cable connection boxes of transformers with highest voltage for equipment from U m=72,5kV to 550kV, including the conductor current terminal with removable link between the transformer and the dry-type cable termination.
