Available for: Grid Substations, Industrial Plants, Renewable Energy Sites.
An Oil Immersed Power Transformer is a critical electrical device used in power distribution networks to step up or step down voltage levels. Unlike dry-type transformers, these units utilize mineral oil for insulation and cooling, offering superior heat dissipation and higher voltage capacity. They are the standard for outdoor substations and heavy industrial applications where efficiency and longevity are paramount.
| Parameter | Value |

"We sourced 10 units for a substation project in Cebu. The voltage stability is excellent, and the shipping crates handled the ocean freight perfectly."
Ricardo M.
Project Manager, Philippines
"Direct supply from Shanghai saved us about 15% compared to local sourcing. The build quality of the tank is very solid."
Lien N.
Industrial Park Developer, Vietnam
"Consistent performance. We have been running these transformers for 2 years in our mining facility with zero downtime."

For standard specifications, production typically takes 30-45 days. Custom high-voltage units may require 60+ days depending on testing requirements.
We use reinforced steel frames and wooden crates specifically designed for heavy ocean freight to ensure zero damage during transit.
Yes, all our transformers undergo rigorous testing and come with full IEC compliance documentation and factory test reports.
We support flexible orders starting from 1 unit, given the industrial nature and size of the equipment.
Yes, we offer ONAN (Oil Natural Air Natural) and ONAF (Oil Natural Air Forced) options based on your load requirements.
Designed for heavy-duty cycling, our oil-immersed transformers have a design life of 20-30 years under normal maintenance conditions.
