Porcelain insulators LOW VOLTAGE DIFFERENT PURPOSES
Porcelain insulators of low voltage for various purposes are used for insulation of live parts in electrical apparatus and installations in all sectors of the economy and are designed to operate at a nominal voltage up to 1000 V DC and AC frequency of 60 Hz. They are manufactured in climatic version UW, category 2, 3 according to GOST 15150-69 and GOST 15543-70.
Bushings are designed to electrically isolate additional air link wires and electrical DC voltage up to 500 V, 50 Hz during the passage of wires through walls and partitions of buildings, as well as through the walls of instruments and apparatuses.
The material for the sleeves, manufactured by injection - Porcelain Electrical sub-group 110, a pressing method - Porcelain subgroup 111 to GOST 20419-83.
sleeves service life of at least 20 years, the failure rate is 0.0000006 1 / h.
Porcelain insulators of low voltage for different purposes are not used to working in an environment containing conductive dust, corrosive gases and vapors in concentrations destroying porcelain and glaze. The environment should not be explosive.
The insulation resistance of insulators in air 20 megohms after moisture chamber - 2 MW, water absorption is 0.5%.
