Test requirements for low voltage aerial bundled cable accessories - Part 6: Environmental testing

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 6 defines the environmental tests in particular the climatic and corrosion ageing tests. The objective of these tests is to predict the behaviour of ABC accessories when subjected to sun radiation, to weather conditions (humidity, spraying water, heat, cold) and pollution. EN 50483 1, EN 50483 2, EN 50483 3 and EN 50483 4 specify which type tests included in this part of the standard are needed.

36 This is Part 6 of CENELEC standard EN 50483 “Test requirements for low voltage aerial bundled cable
37 accessories”, which has six parts:
38 — Part 1: Generalities;
39 — Part 2: Tension and suspension clamps, fittings and brackets for self supporting system;
40 — Part 3: Tension and suspension clamps for neutral messenger system;
41 — Part 4: Connectors;
42 — Part 5: Electrical ageing test;
43 — Part 6: Environmental testing.
44 Introduction
45 The objective of the EN 50483 series is to provide a method of testing the suitability of accessories when used
46 under normal operating conditions with low voltage aerial bundled cables (ABC) complying with HD 626.
47 Climate differs across Europe and in order to meet the differing geographic climatic conditions it is necessary
48 to provide a range of tests to meet these variations. A range of optional, additional tests is provided to meet
49 the varying climatic needs and these should be agreed between the customer and the manufacturer and/or
50 the supplier (see Annex C).
51 This European Standard does not invalidate existing approvals of products achieved on the basis of national
52 standards and specifications and/or the demonstration of satisfactory service performance. However, products
53 approved according to such national standards or specifications cannot directly claim approval to this
54 European Standard. It may be possible, subject to agreement between the customer and the manufacturer
55 and/or the supplier, and/or the relevant conformity assessment body, to demonstrate that conformity to the
56 earlier standard can be used to claim conformity to this standard, provided an assessment is made of any
57 additional type testing that may need to be carried out. Any such additional testing that is part of a sequence
58 of testing cannot be done separately.
59 1 Scope
60 EN 50483 series applies to overhead line fittings for tensioning, supporting and connecting aerial bundled
61 cables (ABC) of rated voltage U /U (U ): 0,6/1 (1,2) kV.
