EN 50483 series 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 5 applies to the connections described in prEN 50483 4, including branch connectors, Insulation Piercing Connectors (IPC), pre-insulated lugs (terminals) and through pre-insulated connectors (sleeves).
Two classes of connectors are covered by this document:
-  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 5 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.
