DIN 30NF250 High voltage 36kV transformer bushing

DIN 30NF250 transformer bushing

DIN 30NF250 transformer bushing is the main insulation device outside the transformer box. The lead wires of the transformer windings must pass through the insulating bushing to insulate between the lead wires and between the lead wires and the transformer shell, and at the same time play the role of fixing the lead wires. Due to the different voltage levels, insulating bushings include pure porcelain bushings, oil-filled bushings, and capacitor bushings. Pure porcelain bushings are mostly used in transformers of 10kV and below. It is to wear a conductive copper rod in the porcelain bushing, and the porcelain bushing is air-insulated; oil-filled bushings are mostly used in 35kV transformers, which are filled with oil in the porcelain bushing. , Put a conductive copper rod in the porcelain bushing, and the copper rod is covered with insulating paper; the capacitive bushing is used on high-voltage transformers above 100kV. It consists of a main insulating capacitor core, outer insulating upper and lower porcelain parts, connecting sleeves, and oil pillows. , Spring assembly, base, equalizing ball, measuring terminal, terminal block, rubber gasket, insulating oil, etc.

DIN 30NF250 transformer bushing is a hollow electrical insulator that allows an electrical conductor to pass safely through a conducting barrier such as the case of a transformer or circuit breaker without making electrical contact with it. Our manufacturer can produce the porcelain bushing as per the DIN standards
