Overview

EN 50299-1 covers the oil-immersed single-phase connection assembly of cables for transformers and reactors, designed in accordance with EN 60076 (all parts). This standard applies to oil-immersed cable connection boxes on transformers with highest voltage for equipment U_m = 72,5 kV to U_m = 550 kV, including the current conductor terminal at the cable sealing end of the transformer. It complements and amends, if necessary, the relevant IEC standards and applies to oil immersed cable connections, suitable for fluid-filled or dry-type cable terminations. The purpose of EN 50299-1 is to establish for the cable assemblies: the electrical and mechanical requirements, including interchangeability; the limits of supply; the test to be carried out. EN 50299-1 does not cover direct cable terminations (see 3.1.1.3), but, in this case, upon agreement between purchaser and supplier, the standard may be used for guidance. EN 50299-2 partially supersedes EN 50299:2002, together with EN 50299-1:2014. The new standard EN 50299-2 is issued which describes requirements for dry-type cable terminations only. Dimensions mentioned in 50922-1 are valid for fluid-filled cable terminations. Dry-type cable terminations may also fit to these requirements. The responsible committee is Subcommittee DKE/UK 321.2 "Transformatoren, Leistungen und Abmessungen" ("Transformers, performances and dimensions") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
