Overview

EN 50299-2 covers the oil-immersed single-phase connection assemblies of cables for transformers and reactors designed in accordance with EN 60076 (all parts). This standard applies to oil-filled cable connection boxes of transformers with highest voltage for equipment from U_m = 72,5 kV to U_m = 550 kV, including the conductor current terminal with removable link between the transformer and the dry-type cable termination. 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 EN 62271-209. The purpose of EN 50299-2 is to establish for the cable connection assemblies: electrical and mechanical requirements including interchangeability, limits of supply, tests to be carried out. 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. 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.
