    Abstract - (Show below) - (Hide below)

    Describes composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibres - usually glass - in a resin based matrix, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core.

    Scope - (Show below) - (Hide below)

    IEC 61109:2008 applies to composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibres - usually glass - in a resin-based matrix, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core. The main technical changes with respect to the previous edition are
    - removal of tests procedures now given in IEC 62217;
    - inclusion of clauses on tolerances, environmental conditions, transport, storage and installation;
    - general improvement of the description of tests and addition of a new Annex C on non-standard loads.
