EN Transforner Bushing 1KV/250A

Transformer casing is the main insulating device outside the transformer box, the transformer winding lead wires must pass through the insulating casing, so that between the lead wires and lead wires and transformer shell insulation, and at the same time play a role in fixing the lead wires. Because of the different voltage level, there are pure porcelain casing, oil-filled casing and capacitor casing and other forms. Pure porcelain casing is mostly used for 10kV and the following transformer, it is in the porcelain casing through a conductive copper rod, porcelain sleeve for the air insulation; oil-filled casing is mostly used in the 35kV transformer, it is in the porcelain casing oil-filled, in the porcelain casing through a conductive copper rod, copper rod outsourcing insulating paper; capacitor casing is used for more than 100kV on the transformer on the high-voltage, by the main insulated capacitor core, the outer insulation of upper and lower porcelain parts, connecting Sleeve, oil pillow, spring assembly, base, equalizing ball, measuring terminals, terminals, rubber washers, insulating oil and other components.
