Izolatorët e përbërë të stacioneve të postës për nënstacionet me tensione të rrymës alternative më të mëdha se 1000 V dhe më të vegjël se 245kV - Përcaktimet, metodat e provës dhe kriteri e pranimit

Composite station post insulators for substations with a.c. voltages greater than 1 000 V up to 245 kV - Definitions, test methods and acceptance criteria

Scope

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.
