Oil Immersed Distribution Transformer

Low-loss high-performance silicon steel core with 0.27mm thin material, which reduces no-load loss by over 18% compared with traditional transformers, cutting long-term power operation costs for clients. The core adopts 45° full miter joint structure, effectively lowering noise during operation to below 55dB for quiet working environment.

All-sealed corrugated radiator oil tank design, the radiator fins automatically expand and contract with oil temperature to balance internal pressure, avoiding oil leakage risk. The surface is treated with anti-rust electrostatic spraying, resisting rain, dust and ultraviolet rays for outdoor long-term service life over 15 years.

High & low voltage insulation porcelain bushing with strong anti-breakdown performance, equipped with color-coded wiring terminals for clear phase identification. Standard oil level gauge, pressure relief valve and temperature detection components are pre-installed to monitor running status in real time and prevent over-temperature faults.

High-purity oxygen-free copper winding with uniform winding process, good heat conductivity and strong overload resistance, capable of enduring short-time overload operation without coil burning. The insulating oil has excellent arc extinguishing and cooling performance, ensuring stable insulation under long-term continuous operation.

Fully comply with IEC international standards and pass CE certification, all raw materials go through strict factory inspection. We support customized capacity, voltage ratio and anti-salt spray treatment for coastal, mining and high-temperature industrial environments, with complete installation accessories supplied.

◉ Urban municipal power grid: This oil immersed transformer realizes voltage reduction for residential communities, street lighting and commercial plazas, converting high-voltage grid power into safe 0.4kV low voltage for daily civil electricity consumption.

◉ Photovoltaic & wind power stations: Matched with new energy power generation systems to step down generated electric energy, with low loss and stable operation adapting to outdoor wild construction environments.

◉ Factory & industrial park power supply: Serves as core voltage conversion equipment for manufacturing plants, logistics parks and mining areas, providing stable low voltage power for production equipment, motors and workshop lighting.

◉ Construction temporary engineering: Widely used in large construction sites, scenic spots and water conservancy projects to solve large-capacity temporary power demand, featuring convenient installation and reliable overload protection.

Place the transformer on flat foundation and fix with anchor bolts, connect high and low voltage cables to corresponding bushings. Check oil level and tightness of all valves before power transmission. Download full PDF operation manual for regular oil inspection, fault judgment and maintenance guidance.

Can the transformer capacity and voltage ratio be customized as required?

Yes, we produce transformers from 10kVA to 2500kVA, and adjust high/low voltage ratios according to local grid standards. Free technical parameter drawings will be provided before mass production.
