35kV dry-type power transformer is specially designed for 5000kVA to 10000kVA capacity applications in urban substations, industrial plants and infrastructure projects. Built with a sturdy IP54 enclosure, it uses an oil-free, epoxy resin cast structure that brings safe, clean and stable power supply to demanding working sites.
Suitable for 50Hz and 60Hz three-phase AC systems, this transformer comes with reliable vacuum-cast windings, AN/AF dual cooling and off-load tap changing. The IP54 protection effectively keeps out dust, rain and splashing water, allowing stable outdoor and semi-outdoor operation without extra housing or protection.
With high efficiency, low noise, strong short-circuit resistance and maintenance-free design, this transformer fully meets IEC 60076 and GB/T 10228 standards. It provides long-term dependable performance for industrial power, grid distribution and modern energy projects.
| Rated Voltage | 35kv |
