Main Overview:

SC(B)H19 represents our highest‑efficiency amorphous alloy dry‑type transformer series. It adopts premium amorphous alloy core with hysteresis loss merely 20‑30 % of conventional silicon‑steel core. High‑voltage windings are fully sealed via epoxy resin vacuum casting; Class‑H insulation endures 180 °C with over 30‑year design service life.

Oil‑free flame‑retardant construction eliminates fire hazards; core material is fully recyclable. This model supports voltage levels up to 35 kV, delivers industry‑leading no‑load‑loss reduction, ultra‑quiet operation and strong high‑humidity adaptability. Taking a 1000 kVA unit as example, annual energy saving exceeds 15000 kWh with significant lifecycle CO₂ reduction. It is the premium solution for high‑end carbon‑neutral power distribution projects. Capacity range:30 kVA‑2500 kVA.

Product features:

1. Industry-Leading, Extreme Energy Efficiency
High-quality amorphous alloy cores reduce hysteresis losses to 20–30% of those in silicon steel cores and lower no-load losses by 70–80%. For a 1,000 kVA transformer, annual electricity savings exceed 15,000 kWh, significantly reducing operating expenses (OPEX) and achieving substantial CO₂ emissions reductions over the entire lifecycle. The SC(B)H19 is the most energy-efficient option in the amorphous dry-type product series.

2. 35 kV High-Voltage Rating and Robust Environmental Adaptability
Supports voltage ratings up to 35 kV. The high-voltage windings utilize full-epoxy vacuum casting technology to enhance mechanical strength and short-circuit resistance, ensuring long-term reliable operation in high-humidity environments. Operating ambient temperature: -25°C to 45°C.

3. Ultra-Quiet Operation, Suitable for Noise-Sensitive Locations
Amorphous alloy material exhibits a weak magnetostrictive effect, resulting in low operating noise. It is particularly suitable for hospitals, schools, indoor substations in city centers, and other locations with strict noise requirements.

4. Class H Insulation Ensures Long-Term Reliability
Class H high-temperature-resistant insulation materials can withstand temperatures up to 180°C, with a designed insulation service life exceeding 30 years. A real-time winding temperature monitoring system predicts potential failures in advance, ensuring safe equipment operation.

5. Eco-Friendly Design
The amorphous core material is 100% recyclable. The completely oil-free design eliminates fire hazards and fully complies with international environmental directives, supporting green power distribution projects.

6. Intelligent Thermal Protection and Flexible Customization
Equipped with a real-time winding temperature monitoring system. Optional features include forced air cooling, no-load tap changers, and anti-condensation heaters to meet specific on-site requirements. Copper windings are standard; aluminum windings are available as an alternative.
