35kV Class And Below Dry-Type Dual-Split Transformer

The dry-type dual-split transformer is a special type of transformer characterized by having two independent low-voltage windings, which can supply power to different loads respectively. The dual independent secondary winding design achieves fully enclosed insulation through high-precision epoxy resin vacuum casting. The rated voltage covers 10kV to 35kV, with a capacity range of 630kVA to 16MVA. It offers protection levels up to IP54 and Class F/H temperature withstand. Specifically designed for renewable energy applications such as PV, wind power, and energy storage, as well as data centers, semiconductor plants, and hospitals. When a fault occurs in one load circuit, the other split winding continues to supply power, ensuring zero interruption to critical loads.

Dual Power Supply Safety Guarantee: When a fault occurs in one load circuit, the other split winding continues to supply power. One transformer, dual supply – the architecture saves 50% space and 25% equipment procurement cost.

Precise Electromagnetic Balance: The symmetry deviation of the split windings is <2%, meeting the ampere-turn balance requirement. This solves the problem of large dimensional deviation between the upper and lower windings.

Compact Structure Design: The footprint is reduced by 45% compared to two independent transformers. The internal ventilation of the protective enclosure is optimized, reducing hot-spot temperature rise.
