Over deze norm
EN 50483 applies to overhead line fittings for tensioning, supporting and connecting aerial bundled cables (ABC) of rated voltage U0/U (Um): 0,6/1 (1,2) kV. This part applies to the connections described in EN 50483-4, including branch connectors, Insulation Piercing Connectors (IPC), pre-insulated lugs (terminals) and through pre-insulated connectors (sleeves). The objective is to provide a method of testing the suitability of connectors when used under normal operating conditions with low voltage aerial bundled cables complying with HD 626. Two classes of connectors are covered by this standard: Class A: These are connectors intended for electricity distribution or industrial networks in which they can be subjected to short-circuits of relatively high intensity and duration. As a consequence, Class A connectors will be suitable for the majority of applications. Class B: These are connectors for networks in which overloads or short-circuits are rapidly cleared by the operation of protection devices. Depending on their application, the connectors are subjected to heat cycles and short-circuit current tests. Class A: the connectors are subjected to heat cycles and short-circuit current tests. Class B: the connectors are subjected to heat cycles only. The object of this part is to define the heating cycles test methods and requirements which apply to compression through connectors, insulation piercing connectors and all other type of connections for low voltage aerial bundled cables. Formerly, approvals for such products have been achieved on the basis of national standards and specifications and/or the demonstration of satisfactory service performances. The publication of this standard does not invalidate existing approvals. However products approved to such earlier standards or specifications shall not claim approval to this standard unless specifically tested to it.
