Covers for coupling capacitors, current and voltage transformers
Non-reinforced ceramic covers. These covers are designed for outdoor operation of coupling, power takeoff and voltage divider capacitors on AC or DC high voltage power lines and provide both reliable operation of high voltage power lines and power system stability. These covers are designed for 35 up to 1150 kV current transformers. These covers operate outdoor, serve as an external insulation and protect transformers inside parts from weather and mechanical im-pacts. Made in conformity with ГОСТ 5862-79 standards. Insulating part is made of ceramic electrotechnical material of subgroup of 110 ГОСТ 20419-83.
