SC(B)H15 Amorphous Alloy Dry-Type Transformer
Model meaning
Structural features
◇ Safe, flame-retardant, fire-proof, pollution-free, and can be directly installed at the load center;
◇ High mechanical strength, strong short-circuit bearing capacity, safe and reliable operation;
◇ Maintenance-free, easy to install, and low overall operating cost;
◇ Good moisture-proof performance, can operate normally under 100% humidity, and can be put into operation without pre-drying after shutdown;
◇ Low loss, low partial discharge, low noise, strong heat dissipation capability, and can operate at 150% rated load under forced air cooling conditions;
◇ Equipped with a complete temperature protection control system. Provide reliable guarantee for the safe operation of the transformer;
◇ The notable features of amorphous alloy dry-type transformers are small no-load losses and relatively low economic operation and load rates:
◇ Especially suitable for industrial and mining enterprises with a load rate of 50% to 80% and a three-shift system;
◇ Amorphous alloy transformers are very beneficial to the reliable operation of power distribution equipment, energy saving and operating cost saving;
◇ Amorphous alloy dry-type transformers have low loss, less heat, low temperature rise, and stable operating performance;
◇ Amorphous alloy dry-type transformers have strong overload capacity, are safe and reliable, have strong corrosion resistance, and are maintenance-free. They can be widely used in places that require uninterrupted power supply, such as national defense, basements, and high-rise buildings.
