1.Scope and object of IEC61109:2008 INSULATORS FOR OVERHEAD LINES – COMPOSITE SUSPENSION AND TENSION INSULATORS FOR A.C. SYSTEMS WITH A NOMINAL VOLTAGE GREATER THAN 1 000 V – DEFINITIONS, TEST METHODS AND ACCEPTANCE CRITERIA

Scope and object This International Standard applies to composite suspension/tension insulators consisting of a load-bearing cylindrical insulating solid core consisting of fibers – 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. Composite insulators covered by this standard […]

Uprating of composite insulators of OH lines

The creation of composite insulator started before the 1960s. This new insulator was firstly applied in America and then in France and Germany soon afterwards. It was quite slow for user to accept insulator with silicone rubber material in the beginning as most technical innovation would have some key problems to solve in the history. […]

Introduction of IEC61109 Insulators for overhead lines – Composite suspension and tension insulators for a.c. systems with a nominal voltage greater than 1 000 V – Definitions, test methods and acceptance criteria

Composite insulators consist of an insulating core, bearing the mechanical load protected by a polymeric housing, the load being transmitted to the core by end fittings. Despite these common features, the materials used and the construction details employed by different manufacturers may be quite different. Some tests have been grouped together as “Design tests”, to be performed only […]
