What is BS EN 50393 - Accessories for use on distribution cables of rated voltage 0,6/1,0 (1,2) kV about?
BS EN 50393:2015 details the performance requirements and the test methods for type testing of cable accessories for use with power distribution cables of rated voltage 0,6/1,0 (1,2) kV as defined in HD 603 or other relevant cable standards.
Cable accessories covered by this European Standard include joints, stop ends, and outdoor terminations for extruded solid dielectric insulated cables and transition joints between extruded solid dielectric insulated and impregnated paper insulated cables.
Joints, stop ends and outdoor terminations for impregnated paper insulated cables are not included.
The service operating conditions of accessories should be compatible with the service operating conditions of cables on which they are to be installed.
Accessories for special applications such as submarine, shipboard, explosive or seismicenvironments, or where specified fire performance characteristics are required, are not included.
