High Efficiency 3-Phase Copper Dry Cast Resin Distribution Transformer for EV Charger

The windings are fully encapsulated in solid epoxy resin, which seals out moisture completely and gives the insulation inherent flame-retardant properties.

A void-free cast construction provides exceptional mechanical strength, allowing the transformer to endure severe short-circuit forces without structural deformation.

Cooling relies solely on air, either natural or forced, eliminating oil entirely along with the risks of leaks, spills and expensive containment systems.

Because there is zero oil inside, the transformer cannot propagate fire, making it the safer choice for high-rise buildings, hospitals, data centers and tunnels.

The non-hygroscopic insulation system resists moisture absorption and performs reliably in high-humidity or polluted environments where liquid-filled units would quickly degrade.

The core and coil assembly is virtually maintenance-free, removing the need for routine oil sampling, filtering and dissolved gas analysis and significantly lowering the total cost of ownership.

All materials are fully recyclable and the transformer reaches end-of-life with a clean disposal path, supporting green building certifications and long-term corporate ESG targets.

Low-loss core materials and optimized winding designs reduce both no-load and load losses, helping operators meet stringent energy codes and achieve lower lifetime operating costs.

Extremely low partial discharge levels and robust cast-resin construction ensure stable long-term operation, with a typical service lifespan exceeding thirty years even in harsh environments.

Every transformer is engineered to order, with adjustments of voltage ratio, impedance, vector group, tap configuration, and enclosure design to fit site and project requirements.
