With a 25 MVA top rating and zero scheduled maintenance, the 20 kV SCB line handles the punishing duty cycles of polysilicon reduction furnaces and large-scale PV plants without breaking stride.
The 20kV energy-efficient SCB series epoxy resin cast dry-type power transformers offer a maximum rated capacity of 25,000 kVA and are designed for three-phase, 50/60 Hz power supply systems. The coils are vacuum-cast with high-quality flame-retardant Class H epoxy resin. The products comply with international and national standards including IEC 60076, GB/T 10228, GB/T 1094, and GB 20052-2024, and hold internationally recognised certifications such as CE and ASTA.
High overload capability – can operate at 150% of rated load under forced-air cooling conditions.
Excellent insulation performance and maintenance-free operation, completely sealed against moisture and dust.
Suitable for locations with stringent safety and environmental requirements.
Widely applied in new energy sectors (wind power, photovoltaic, energy storage) and specialised industrial applications such as polysilicon reduction furnaces.
