EN 50588-4:2018

• Abstract:

  Cable boxes described in this European Standard correspond to cable boxes Type 2 in EN 50588-2 and are suitable for assembly on the cover of oil-immersed distribution transformers meeting the requirements of EN 50588-2. Cable boxes are air-filled, metal- or non-metal enclosed, for high- and/or low-voltage connections in the following variations: 1.1 High-voltage side a) Connection directly to bushings; b) Connection via busbar system. 1.2 Low-voltage side a) Connection directly to bushings (maximum of four connectors per bushing); b) Connection via busbar system.
