BS EN 61109:2008 Insulators for overhead lines. Composite suspension and tension insulators for a.c. systems with a nominal voltage greater than 1000 V. Definitions, test methods and acceptance criteria

BS EN 61109 applies to composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibres – usually glass – in a resinbased matrix, a housing (outside the insulating core) made of polymeric material and end fittings permanently attached to the insulating core.

Composite insulators covered by BS EN 61109 are intended for use as suspension/tension line insulators, but it should be noted that these insulators can occasionally be subjected to
compression or bending, for example when used as phase-spacers.

BS EN 61109 can be applied in part to hybrid composite insulators where the core is made of a homogeneous material (porcelain, resin).

The object of BS EN 61109 is to
– define the terms used,
– prescribe test methods,
– prescribe acceptance criteria.

BS EN 61109 does not include requirements dealing with the choice of insulators for specific operating conditions.
