Description

The 35 kV Oil-immersed Power Transformer is designed with advanced engineering, high-quality materials, and a compact, robust structure to deliver efficient, reliable, and long-lasting performance. Its premium silicon steel core and oxygen-free copper windings minimize energy loss, while the corrugated oil tank design improves cooling efficiency and reduces noise. A capsule oil storage system further enhances insulation life and reduces maintenance needs, ensuring stable operation even under demanding conditions.

Engineered for urban and rural power distribution networks, industrial facilities, and agricultural applications, this transformer combines energy efficiency, mechanical durability, and operational safety to meet modern power system requirements.

Advantages

• High Efficiency: Cold-rolled silicon steel core reduces no-load loss and operating costs.

• Reliable Operation: Oxygen-free copper windings with reinforced supports resist deformation and extend service life.

• Robust Mechanical Strength: Six-sided rigid fixation and durable frame design withstand transport and operational stress.

• Efficient Cooling & Low Noise: Corrugated tank design improves heat dissipation while suppressing noise.

• Extended Oil and Insulation Life: Capsule oil storage system slows oil aging and maintains strong insulation performance.

• Low Maintenance: Accurate oil level monitoring and gas relay system simplify operation and servicing.
