100kVA 11kv Oil Immersed Transformer Introduction
Applications
1. Building Infrastructure and Industrial: Airports, hospitals, factories, shopping malls, hotels, commercial and residential towers.
2. Utility: Generation, transmission, distribution substations, water and waste water treatment plants.
3. Oil and Gas: Oil and gas plants, petrochemical plants and refineries.
Service environment:
1. Ambient temperature: Maximum +40ºC, Minimum -40ºC.Parameters can also be customized according to the customer's environment, such as long-term stable operation in a 55 ºC desert environment
2. Altitude: less than 1000 meters.
3. Seismic level: less than 3m/s2 at horizontal direction and less than 1.5m/s2 at vertical direction.
4. Installation environment: No obvious and heavy pollution, no explosive and corrosive gas and dust, with good air ventilation and no severe vibration and shock.
(Note: If the application environment is different from the above standard conditions, please contact for customized designs.)
Iron core:
The iron core is made of brand new and excellent silicon steel sheets.
Ensure that customers maintain low wear and tear during use, low noise during operation, and more energy-efficient requirements
Winding:
Use heat-resistant enameled wire.
Ensure good conductivity, stable operation, enhanced overload capacity, low line loss, and resistance to oxidation of the winding.
Extend the lifespan of transformers
Transformer oil tank:
The transformer oil tank is composed of corrugated walls that can breathe.
Excellent corrugated walls can compensate for changes in transformer oil volume caused by temperature rise and fall. Therefore, we cancelled the design of the oil storage tank for the transformer. This not only reduces the cost of the transformer, but also lowers the overall height of the transformer. Saved users' various costs.
Safety protection device:
We will equip the transformer with sensitive relief valves and precise glass thermometer sockets.
Of course, we can also equip trip terminals with alarms and gas relays according to customer requirements.
Everything is just to ensure your safety during use.
