Oil-Immersed Transformer
01
SBH Series Oil Immersed Transformer, Class I Energy Efficiency
Model Definition
Features
● Voltage level: 10~35/0.4kV
● Capacity: 30~2500kVA
● Core Material: Utilizes an amorphous alloy core with an optimized molecular structure to ensure precise three-phase magnetic balance, effectively preventing the generation of third harmonics through its uniform magnetic properties.
● Harmonic Filtering: Incorporates a specially designed low-voltage coil structure with an interleaved winding arrangement, which works to dynamically reduce higher-order harmonics by balancing magnetic field distributions.
● Energy Efficiency: Takes advantage of the core material’s superior magnetic characteristics to significantly cut down on no-load losses and minimize excitation current, achieving notable energy-saving performance that meets high-efficiency standards.
● Sealing Technology: Adopts a fully sealed tank design combined with a vacuum oil injection process, which creates a protective barrier against oxidation and leakage. This design requires no maintenance and is built to ensure a long operational lifespan.
● Thermal Performance: Features a low-heat-generating design paired with an efficient heat dissipation system, allowing the equipment to handle overload conditions effectively while maintaining stable thermal performance.
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.
