Anotation

This International Standard applies to composite station post insulators consisting of a load bearing cylindrical insulating solid core made of resin impregnated fibres, a housing (outside the insulating solid core) made of elastomer material (e.g. silicone or ethylene-propylene) and end fittings attached to the insulating core. Composite station post insulators covered by this standard are subjected to cantilever, torsion, tension and compression loads. They are intended for substations with a.c. voltages greater than 1 000 V up to 245 kV. La presente Norme internationale sapplique aux supports isolants composites rigides a socle constitues dun noyau isolant plein cylindrique supportant les charges mecaniques realise en fibres impregnees de resine, dun revetement (a lexterieur du noyau plein isolant) realisee en materiau elastomere (par exemple du silicone ou de lethylene-propylene) et des armatures dextremite fixees au noyau isolant. Les supports isolants composites rigides a socle relevant de la presente norme sont soumis aux charges de flexion, de torsion, de traction et de compression. Ils sont destines aux postes a courant alternatif de tensions superieures a 1 000 V jusqua 245 kV.
