BUSHING INSULATORS TYPE D
Bushing insulators are designed to provide electrical connections between circuits through the chambers of an enclosure or partition while ensuring electrical insulation. Bushing insulators are used in electric motors, pumps, transformers, switchgear, and electrical equipment. Bushing insulators consist of copper through-pins positioned along the axis of a brass sleeve with a thrust flange, effectively electrically insulated by insulating materials placed between them.
