Product Overview:OPTA type oil-paper capacitive AC transformer bushing
The transformer bushing is the main insulation device outside the transformer and reactor oil tank, and the lead wire of the transformer winding must pass through the insulating sleeve to insulate the lead wire and between the lead wire and the transformer oil tank, and at the same time play the role of fixing the lead wire.
