Hollow insulators
I. DIMENSIONAL LIMITS OF HOLLOW INSULATORS
Description:
Hollow insulators made of porcelain material C130, as single-part components, dimensions as specified in drawing. Supplied with or without fittings. Possible fittings: aluminum or hot-dip galvanized cast iron, connected with the porcelain body using portland cementing. High resistance to bending and pressures loads.
Applications:
For outdoor and indoor power equipment to be operated in AC systems up to 100 Hz. Examples: switches, disconnectors, earthing switches, measuring transformers, surge arresters, bushings, cable terminals and capacitors.

II. DIMENSIONAL LIMITS OF GLUED HOLLOW INSULATORS
Description:
Hollow insulators made of ceramic material C130 as multi-sectional bodies connected by gluing, dimensions see drawing. Supplied with or without fittings. Possible fittings: aluminum or hot-dip galvanized cast iron, connected with the porcelain body using portland or sulphur cementing. High resistance to bending and pressures loads.
Applications:
For outdoor and indoor power equipment to be operated in AC systems up to 100 Hz. Examples: switches, disconnectors, earthing switches, measuring transformers, surge arresters, bushings, cable terminals and capacitors.

III. HOLLOW INSULATOR TYPES
Description:
The types and forms of the hollow insulators depend on customer requirements and application. With or without sheds, cylindrical, conical or barrel shaped, with regular or alternating sheds, assembling sections: flat, gritted, grooved or profiled, surface with required roughness for sealing, with or without end fittings. Shape examples see drawing.
Applications:
For outdoor and indoor power equipment to be operated in AC systems up to 100 Hz. Examples: switches, disconnectors, earthing switches, measuring transformers, surge arresters, bushings, cable terminals and capacitors.
