Description
Primary current up to 5000 A. The paper insulation is impregnated with a biodegradable ester per OECD 301, which makes the unit suitable for water protection zones. External insulation is porcelain or composite. The dimensions match the oil-filled equivalents, so the unit is installed in place of an oil-filled one without changing the layout.
