SBH15/21/25-M.RL Series
Amorphous alloy oil immersed transformer
(RL three-dimensional coiled iron core)
Capacities from 30kVA to 5500kVA

- Voltage level: 10-35/0.4KV
- Capacity: 30-2500KVA.
- With three-dimensional rolled core, three-phase balance, no third harmonic.
- Filtering effect: The special structure of the low-voltage coil can effectively filter out high-order harmonics.
- Significant reduction in no-load loss and no-load current, with excellent energy saving effect.
- Fully sealed oil tank and vacuum oil injection technology prevent oil aging, no oil leakage, and maintenance free, long service life.
- Low heat generation, good heat dissipation, and strong overload capacity.
Range of application:
Power distribution for power grid construction, power distribution engineering renovation projects, high-rise buildings, densely populated residential areas, important government agencies, airports, subways, stations, industrial and mining enterprises, petrochemicals, power plants, ports and docks, and other places with requirements for fire and explosion prevention.
