EN 50299:2002
(Main)Oil-immersed cable connection assemblies for transformers and reactors having highest voltage for equipment Um from 72,5 kV to 550 kV
Oil-immersed cable connection assemblies for transformers and reactors having highest voltage for equipment Um from 72,5 kV to 550 kV
This standard covers the oil-immersed single-phase connection assembly of cables for transformers and reactors, designed in accordance with EN 60076 series and with EN 60289, respectively. NOTE In the standard the term "transformer" is used as common definition for transformer and reactor. The purpose of EN 50299 is to establish for the cable assemblies: • the electrical and mechanical requirements, including interchangeability; • the limits of supply; • the test to be carried out. 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. EN 50299 does not cover direct cable terminations (see 3.3.3), but, in this case, upon agreement between purchaser and supplier, the standard may be used for guidance except for Figure 1 and Figure 2 which are not applicable. This standard applies to oil-immersed cable connection boxes on transformers with highest voltage for equipment Um = 72,5 kV to 550 kV, including the current conductor terminal at the cable sealing end of the transformer.

EN 50299 on 2002-10-01.
The following dates were fixed:
- latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2003-10-01
- latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2005-10-01
The contents of the corrigendum of April 2004 have been included in this copy.
