Sh15-M-Rl- (30-2500) Model Transformer for Reliable Energy Management Applications

Model meaning: "S" indicates three-phase, "H" represents amorphous alloy core, "15" is the performance level code, "M" indicates fully sealed, "Rl" might be a specific manufacturer's characteristic identifier or improvement type. The parentheses "30-2500" represent the rated capacity range from 30kVA to 2500kVA.
Basic parameters: The rated voltage is usually 10kV/0.4kV, the frequency is 50Hz, the phase number is three-phase, the cooling method is generally oil-immersed self-cooling, the insulation grade is A, the short-circuit impedance is between 4% and 6%.
Structural features: The core is made of amorphous alloy material, featuring low loss and high magnetic permeability. The windings use high-quality copper wire to ensure stable electrical performance. The oil tank is of a fully sealed structure, which can prevent oil oxidation and external pollution, and is equipped with pressure release valves, oil level gauges, thermometers, etc. as protection devices, ensuring safe and reliable operation.
Performance advantages: The no-load loss is reduced by more than 70% compared to traditional silicon steel sheet transformers, the load loss is reduced by more than 30%, with significant energy-saving effects, effectively reducing energy management's power loss. At the same time, the characteristics of amorphous alloy materials make the transformer noise level lower than 45dB, ensuring quiet operation. The temperature rise of the oil layer does not exceed 55℃, the temperature rise of the windings does not exceed 60℃, the core temperature rise is low, which can reduce the aging speed of insulation materials and extend the service life.
Application scenarios: Suitable for high-rise buildings, commercial centers, subways, airports, etc. Especially suitable for reliable energy management systems with high energy-saving requirements and strict noise limitations, as well as for occasions where power supply stability and energy saving are required in industrial and mining enterprises.
