3 3. Composite Insulator: Composite Insulator shall consist either of individual sheds mounted on the core, with or without an intermediate sheath, or alternatively, of a housing directly moulded or cast in one or several pieces on to the core. 3.2 Core of a composite insulator : It shall be designed to ensure the mechanical characteristics. The core usually consist of either fibers (e.g. glass) which are positioned in a resin based matrix or a homogeneous insulating material (e.g. porcelain or resin). 3.3 Core diameter : The core diameter shall be:- - The geometric diameter of a core of circular section, and to be 18 mm for insulators of SML 120.above that shall be 22 mm. 3.4 Housing and sheds of a composite insulator: It shall provide the necessary creepage distance and protect the core from the weather. An intermediate sheath made of insulating material is a part of the housing. A shed shall be a projecting part of the housing intended to increase the creepage distance. The sheds can be with or without ribs. The housing material shall be high temperature vulcanized silicon rubber (HTV). 3.5 Metal fitting of a composite insulator : The metal fittings shall be intended to connect to a supporting structure, or to a conductor, or to an item of equipment, or to another insulator. 3.6 Connecting zone : Zone where the mechanical load shall be transmitted between the rod and the metal fitting. 3.7 Coupling : The coupling shall be ball and sockets according to IEC The following shall be considered during tests and if will be found not acceptable according to IEC (Version 2.0) the insulators will be rejected:- A) Tracking: Tracking shall be an irreversible degradation by formation of paths starting and developing on the surface of an insulating material. These paths are conductive even under dry conditions. 53

4 Tracking can occur on surfaces in contact with air and also on the interfaces between different insulating materials. B) Treeing : Treeing shall be an irreversible degradation consisting of the formation of microchannels within the material which can be conducting or non- conducting. These microchannels can progressively extend through the bulk of the material until electrical failure occurs. C) Erosion : Erosion shall be an irreversible and non-conducting degradation of the surface of the insulator that occurs by loss of material. This can be uniform, localized or tree-shaped. D) Chalking (flouring): Chalking shall be the appearance of some particles of the filler of the housing material forming a rough or powdery surface. E) Crazing : Crazing shall be made of surface micro-fractures of depths approximately 0.01mm to 0.1mm. F) Crack : Any surface fracture of depths greater than 0.1mm. G) Hydrolysis phenomena: Hydrolysis phenomena, due to water penetration in liquid form or as water vapor, can take place in the materials of the composite insulator which can lead to electrical and/ or mechanical degradation. H) Specified mechanical load (SML) : The SML shall be load indicated in requirement specification which is used for mechanical tests. I) Routine test load (RTL) : The RTL shall be the load applied to all assembled composite insulators during a routine mechanical test. 7.C STANDARDS The following or equivalent standards shall be considered in the design or testing of the offered insulators.
