An oil-immersed distribution transformer is a critical component for stable and efficient power delivery across modern electrical grids. At Hangzhou Liyi Electrical Equipment Co., Ltd., we engineer these high-performance devices to meet rigorous global power industry demands. Our oil-filled units provide exceptional thermal management and electrical insulation. Whether upgrading an industrial facility or expanding a municipal grid, our solutions minimize energy loss. We combine advanced engineering with robust materials to maximize operational uptime for diverse applications.
We offer a comprehensive range of transformer solutions to accommodate diverse voltage and capacity requirements. Our product lineup ensures every project has access to the right power distribution technology. This includes large-scale industrial complexes and localized rural networks.
Our three-phase oil-immersed distribution transformers are engineered for high magnetic conductivity and superior energy efficiency. These units feature hermetically sealed designs to prevent oil degradation and moisture ingress. This ensures long-term reliability with minimal maintenance. They are perfectly suited for large-scale industrial and commercial power grids requiring consistent, heavy-duty power delivery.
For projects requiring a compact footprint, our single-phase oil-immersed distribution transformers offer an ideal balance of efficiency and space-saving design. These variants are highly effective for rural electrification initiatives and residential areas. They also serve localized power distribution networks where three-phase power is unnecessary.
We manufacture every oil-immersed distribution transformer to strict international standards, including IEC and ANSI protocols. This commitment to quality ensures our units deliver optimal electrical performance and safety under varying load conditions. Below is a general overview of our standard technical parameters.
| Parameter | Specification Range |
|---|---|
| Rated Capacity (kVA) | 10 kVA to 2500+ kVA (Customizable) |
| Primary Voltage Combinations | 11kV, 22kV, 24kV, 33kV series |
| Secondary Voltage | 0.4kV, 0.415kV, 0.433kV |
| No-load Loss | Optimized for high efficiency (Standard specific) |
| Cooling Method | ONAN (Oil Natural Air Natural) |
| Compliance Standards | IEC, ANSI, IEEE |
Proper site planning is crucial for the successful deployment of any power transformer. We provide detailed general arrangement drawings, footprint dimensions, and precise weight classes for all models. Our engineering data assists procurement managers and site engineers in preparing structural supports and safety clearances. This applies whether you require pole-mounted installations or pad-mounted configurations for heavier systems.
