I. Product Introduction
The 10 kV series oil-immersed distribution transformer is a next-generation, high-efficiency, energy-saving transformer. An industry-leading solution for power distribution networks, it delivers exceptional energy savings and operational reliability. Equipped with high-permeability silicon steel sheets, a fully sealed design, and optimized core manufacturing processes, this transformer exhibits lower energy losses and reduced noise levels. Widely used in 10 kV distribution systems, it is particularly suitable for power systems requiring strict energy efficiency, quiet operation, and safety requirements.
2. Technical characteristics (customizable)
• Communication group: Dyn11
• Cooling method: ONAN oil immersion self-cooling
• Rated power: 10KVA-5000KVA
• Energy efficiency class: highly efficient and energy saving transformer
• Impedance voltage: 4%
3. Key Features
1. Ultra-low loss: Long-term operation significantly reduces energy costs and ensures a quick return on investment.
2. Extremely low operating noise: The iron core adopts multi-stage connections and optimized magnetic circuit, ensuring minimal vibration and low noise, which meets the quiet requirements of residential areas, schools, hospitals and other environments.
3. The fully sealed, maintenance-free design adopts a corrugated oil tank structure, which isolates the transformer oil from the air, effectively preventing oxidation and moisture absorption, thereby eliminating the need for core lifting and regular maintenance.
4. With robust coil structure and stable insulation, it exhibits strong short-circuit resistance, can withstand power surges and load fluctuations, ensuring safe and reliable operation.
5. Long service life with reasonable heat dissipation system, corrosion resistance and weather resistance, the overall service life is more than 20 years and the failure rate is low.
6. Compact structure with easy installation, small size and light weight, suitable for various installation scenarios including outdoor platforms, distribution rooms and box-type substations.
