At 35 kV — the upper limit of our dry-type portfolio — every unit leaves the JOERG line with robotic-stacked cores and vacuum-cast coils that shrug off 100 % humidity and grid-side fault currents alike.
The 35kV energy-efficient SCB series epoxy resin cast dry-type power transformer offers a maximum rated capacity of 25,000 kVA. It is manufactured using vacuum casting with epoxy resin, and the core is produced on fully automatic JOERG production lines with robotic stacking technology. The company’s core product portfolio is built around thin-insulation filled dry-type transformers. Through digital design, intelligent manufacturing, and visual management systems, conventional electrical equipment is upgraded into smart terminal devices. The transformers comply with international and national standards including IEC 60076, GB/T 10228, GB/T 1094, and GB 20052-2024, and hold CE and ASTA certifications.
Equipped with on-load tap changers for automatic voltage regulation under load.
Operable at 100% humidity with outstanding moisture resistance.
High mechanical strength and robust short-circuit withstand capability.
Extensively applied in new energy, rail transit, state power grids, data centres, and petrochemical industries.
The company’s highest voltage level reaches 35 kV, reflecting deep technological expertise built over years.
