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 tensioning devices consisting of tension and suspension clamps designed to be used for installation of self-supporting ABC defined in HD 626. Tests described in this document are type tests. Their purpose is to ensure the user that the accessories complying with the tests will operate properly as far as the continuity and the quality of series manufacturing are concerned. 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. The performance characteristics of all clamps shall be proven by satisfactorily undergoing the range of tests listed in this standard. Each clamp shall be tested for the smallest and largest bundled conductor size for which it is marked.
