Supporting insulators with a nominal working voltage over 1kV

Types: ETA 12, ETB 12, ETC 12, ETB 24-1, ETB 24-2, ETB 40, ETC 40

Standard: MSZ IEC 273, MSZ EN 60 660, VSZM TS 51-86

Application field: For indoor or outdoor application at nominal voltage range above 1 kV

Material: Epoxy casting resin filled with silica flour (for indoor application)

Colour: red (for indoor application)

According to requirements we can produce insulators made of cyclo-alyphatic epoxy casting resin system for outdoor application as well. Insulators for outdoor use are unpainted or they can be coloured according to agreements.

Dimensions and shaping: for example: ETB 12
