Three Phase Dry Type Transformer

Zhejiang Jiangshan Hengli Electrical Co., Ltd. is one of the leading manufacturers and suppliers of three phase dry type transformer in China. If you're going to wholesale durable three phase dry type transformer made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.

We supplied one unit of 1000kVA Three Phase Dry Type Transformer to Africa in 2021.The rated capacity of the Three Phase Dry Type transformer is 1000kVA with AN/AF cooling, the primary voltage is 33kV with ±2*2.5% tapping range (NLTC), the secondary voltage is 6.6kV, they formed a vector group of Dyn11.

Without insulating oil inside, this Three Phase Dry Type Transformer eliminates oil leakage, explosion and fire hazards. It is low noise, dust-proof, moisture-resistant and nearly maintenance-free, perfectly suitable for indoor installation, high-altitude areas, high humidity environments and safety-critical scenarios such as factories, shopping malls, data centers, hospital facilities, photovoltaic and wind energy power stations.

For our Three Phase Dry Type Transformer, we can provide you:

Voltage ratios - Primary from 6 kV to 36 kV; secondary at 0.4 kV, 0.69 kV, or other distribution levels

Vector groups - Dyn11 for mixed loads, Yyn0 for residential distribution, or specialized groups for industrial legacy systems

Tapping - Off-circuit taps at ±2×2.5% for seasonal voltage correction, or on-load tap changers for automatic regulation

Cooling upgrades - AN base rating with AF overload capacity, or continuous AF for compact high-power density

Enclosures - IP20 for clean indoor rooms, IP31 for basic dust protection, IP54 for outdoor or wash-down areas

Oil-filled transformers carry an environmental liability. Leaks contaminate soil, require costly remediation, and in some jurisdictions trigger mandatory reporting. Our cast resin Three Phase Dry Type Transformer units contain no oil, no PCBs, and no hazardous coolants. At end of life, the copper and aluminum windings are recyclable, the steel core is scrap-grade material, and the epoxy resin can be processed through standard industrial waste streams. More immediately, the absence of oil means no fire-containment bund, no oil-level monitoring, and no spill-response plan - simplifying your facility's environmental compliance from day one.

Noise is another environmental factor often overlooked. A transformer humming at 65 dB in a residential basement creates complaints. Our standard designs target 55 dB or lower for medium ratings, and we can specify additional noise-reduction measures - tighter core clamping, vibration-dampening pads, and acoustic enclosures - for sensitive locations.
