Insulators are designed to fix and insulate wires of power transmission lines with the nominal voltage 330 kV, frequency up to 100 Hz with the air temperature from - 60 to + 50 оС. Insulators are designed to fix and insulate wires of power transmission lines with the nominal voltage 330 kV, frequency up to 100 Hz with the air temperature from - 60 to + 50 оС.
Insulators conform to the requirements of IEC 61109.
