Equipment Customized 20kVA 80kVA High Voltage Dry Type Electrical Transformer

Performance features:
Excellent insulation performance: Usually uses insulating materials such as epoxy resin, with low local discharge and strong resistance to lightning strikes.
Fireproof and moisture-proof: Has fire-resistant and fireproof properties, and can be directly operated at the load center. Good moisture-proof performance, able to adapt to high humidity and other harsh environments.
Low loss and low noise: The core is generally made of high-quality cold-rolled silicon steel sheets, with low no-load loss and no-load current. Low noise during operation, significant energy-saving effect, and maintenance-free.
Strong heat dissipation capacity: Cooling methods include natural air cooling (AN) and forced air cooling (AF). In natural air cooling, it can operate continuously for a long time at the rated capacity. In forced air cooling, it can operate at higher capacities.
Main parameters:
Rated capacity: 20 kilovolt-amperes and 80 kilovolt-amperes respectively.
Rated voltage: The high-voltage side can reach 20KV, the high-voltage tap range is usually ±2×2.5% and ±5%, customizable according to customer requirements.
Phase number: Generally 3 phases.
Rated frequency: Usually 50Hz.
Connection group designation: Commonly Dyn11, Yyn0.
Operating conditions:
Altitude: Not exceeding 1000m.
Environmental temperature: Maximum temperature + 40℃, daily average temperature + 30℃, annual average temperature + 20℃, minimum temperature - 30℃ (applicable to outdoor transformers) or - 5℃ (applicable to indoor transformers).
Application scope: With advantages such as strong resistance to thermal shock and insensitivity to humidity and dust, widely used in high-rise buildings, commercial centers, airports, tunnels, chemical plants, etc.
