Oil immersed transformers rely on oil for main insulation and cooling. They adopt a sealed setup. This fully keeps the transformer oil away from surrounding air. In turn, it delivers steadier and safer performance. Maintenance becomes much simpler too.

SHENGTE's energy-saving oil immersed transformer includes a layered iron core build. We combine fresh tech with tested oil immersed transformer methods and our skills in the field. Above all, we focus on strong product trustworthiness. That leads to big drops in no-load loss and no-load current. SHENGTE outdoor type oil immersed transformer fits many different uses. We supply reliable oil immersed distribution transformer for your needs.

Features：

•  Low Axial Short-Circuit Force Coil:

This unique coil setup forms a vital part of our oil immersed transformer build. It cuts down the axial short-circuit force a lot when faults happen. As a result, it boosts the oil immersed transformer's mechanical toughness and power to handle short-circuit shocks. This setup guarantees steady performance over the years.

•  Highly Reliable Supporting Structure:

Our team uses a sturdy support framework. It keeps the top and bottom sections of the coil under even and steady pressure. Such an approach delivers top-notch mechanical steadiness. It also offers solid protection against short circuits. These qualities make it essential for trustworthy oil immersed power transformer work in tough settings.

•  Low Magnetic Flux Density Design:

We craft the core to have a reduced magnetic flux density. This smart choice lowers the oil immersed distribution transformer's no-load losses right away. It raises energy savings. Plus, it stops the core's magnetic flux from getting saturated while running. That helps cut back on third harmonic distortion. In turn, it supports a purer power output.

•  304 Stainless Steel Bolts and Nuts:

For better lasting power and endurance, every outer fastener on our oil immersed distribution transformer relies on 304-grade stainless steel bolts and nuts. This pick fights off rust and decay well in all sorts of surroundings. It preserves the build's strength and keeps a sharp look for a long while.

•  High-Quality Sealing Rubber Rings:

We pick and apply the best sealing rubber options from China. This lets us create a top seal for our wholesale oil immersed transformer items. These fine rings block oil leaks and water entry. They help stretch out the oil immersed power transformer's working life and ensure it runs without needing upkeep.                                  

Our Advantages:

• Excellent Heat Dissipation & Structural Integrity:The spiral coil with longitudinal oil ducts provides superior cooling, low magnetic leakage, and high mechanical strength—essential for oil immersed power transformers. The reinforced supporting structure further enhances short-circuit withstand capability.

• Efficient Iron Core: Utilizing silicon steel sheets under 0.35mm thick with high magnetic conductivity, our oil immersed transformer core minimizes no-load loss and current, delivering superior energy efficiency.

• High-Quality Insulation Materials: Featuring excellent heat resistance, these materials reliably withstand overvoltage and overcurrent, ensuring the long-term durability and safety expected from premium oil immersed distribution transformers.

• Superior Transformer Oil: Specially selected for low viscosity and outstanding heat transfer and insulation properties, the oil protects the core and windings, slows insulation aging, and extends the service life of every oil immersed transformer.

• Durable Oil Tank: Fabricated from high-quality cold-rolled steel plates and treated with de-oiling, rust removal, phosphating, and three-proof paint, the tank maximizes reliability and minimizes maintenance—a key advantage for wholesale oil immersed transformer procurement.

• Effective Sealing Rings: Manufactured from high-quality rubber to slow aging, these rings effectively isolate external air and prevent oil leakage, ensuring the sealed integrity fundamental to all oil immersed transformer operations.
