Test requirements for low voltage aerial bundled cable accessories - Part 5: Electrical ageing test
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.

30 This is Part 5 of CENELEC standard EN 50483 “Test requirements for low voltage aerial bundled cable
31 accessories”, which has six parts:
32 — Part 1: Generalities;
33 — Part 2: Tension and suspension clamps, fittings and brackets for self supporting system;

35 — Part 4: Connectors;

38 Introduction
39 The objective of the EN 50483 series is to provide a method of testing the suitability of accessories when used
40 under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626.
41 This European Standard does not invalidate existing approvals of products achieved on the basis of national
42 standards and specifications and/or the demonstration of satisfactory service performance. However, products
43 approved according to such national standards or specifications cannot directly claim approval to this
44 European Standard. It may be possible, subject to agreement between supplier and purchaser, and/or the
45 relevant conformity assessment body, to demonstrate that conformity to the earlier standard can be used to
46 claim conformity to this standard, provided an assessment is made of any additional type testing that may
47 need to be carried out. Any such additional testing that is part of a sequence of testing cannot be done
48 separately.
49 1 Scope
50 EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled
51 cables (ABC) of rated voltage U /U (U ): 0,6/1 (1,2) kV.
0 m
52 This Part 5 applies to the connections described in prEN 50483-4, including branch connectors, Insulation
53 Piercing Connectors (IPC), pre-insulated lugs (terminals) and through pre-insulated connectors (sleeves).
54 Two classes of connectors are covered by this document:
55 — Class A: These are connectors intended for electricity distribution or industrial networks in which they can
56 be subjected to short-circuits of relatively high intensity and duration. As a consequence, Class A
57 connectors will be suitable for the majority of applications.
58 — Class B: These are connectors for networks in which overloads or short-circuits are rapidly cleared by the
59 operation of protection devices.
60 Depending on their application, the connectors are subjected to heat cycles and short-circuit current tests.
61 Class A: the connectors are subjected to heat cycles and short-circuit current tests.
62 Class B: the connectors are subjected to heat cycles only.
63 The object of this Part 5 is to define the heating cycles test methods and requirements which apply to
64 compression through connectors, insulation piercing connectors and all other type of connections for low
65 voltage aerial bundled cables.
