50KVA Dry Type Transformer

Our 50 kV cast-resin dry type distribution transformer offers 100 kVA – 2 500 kVA in a flame-retardant, IP54 enclosure that needs no oil pit or fire wall, fitting high-rise substations, hospitals and data halls where safety and space are premium. Vacuum-cast Class-F coils with embedded RTDs give 155 °C thermal reserve, zero toxic smoke and self-extinguishing performance in 0.03 s.

Step-lap CRGO core cuts no-load losses 18 % below IEC 60076, saving ~10 MWh per year on a 1 MVA unit; noise is ≤ 55 dB(A) at 1 m, eliminating costly baffles in office corridors. Front-access off-circuit ± 2 × 2.5 % taps or optional 17-step OLTC maintain voltage within ± 1 % for renewable and motor loads.

Compliance: IEC 60076-11, CE, UL 1561, GB/T 10228; ambient – 40 °C to + 40 °C, altitude 3 000 m, seismic 0.3 g. Enclosure colors, top/side cable boxes and double-deck busbar entry are customizable; units ship fully tested and witnessed, ready for energization in 48 hours.

FEATURES

Dive into the engineering excellence that sets our 50KVA Dry Type Transformer apart. This detailed visual breaks down the critical components that guarantee superior performance:
●Epoxy Resin Encapsulation: The coil is vacuum-potted with high-grade epoxy resin, creating a solid barrier that protects against moisture, dust, and corrosive contaminants. This ensures exceptional dielectric strength and prevents partial discharge, significantly extending the transformer’s lifespan.
●Copper Windings: We use 100% electrolytic copper for our windings, which offers higher conductivity and better overload capacity compared to aluminum, leading to lower energy losses and improved efficiency under heavy loads.
●New Silicon Steel Core: Constructed from high-grain-oriented silicon steel, the core minimizes hysteresis and eddy current losses. This results in exceptionally low no-load losses, enhancing overall energy efficiency and reducing operating costs.
●Solid Mounting Base & Heel Block: The robust mechanical design, including the insulated heel blocks and sturdy mounting base, ensures the core and coil assembly remains stable and vibration-free, even during short-circuit events. This reduces mechanical stress and guarantees operational integrity for decades. 未标题-1_03
