hermetic oil transformer

I. Product Introduction

The 10 kV series oil-immersed distribution transformer is a next-generation, high-efficiency energy-saving transformer. As a leading industry solution for power distribution networks, it offers exceptional energy savings and operational reliability. Equipped with high-permeability silicon steel sheets, a fully sealed structure, and optimized core manufacturing processes, this transformer demonstrates lower energy losses and reduced noise levels. Widely used in 10 kV distribution systems, it is particularly suitable for power supply systems that require strict energy efficiency, quiet operation, and compliance with safety requirements.

2. Technical specifications (customizable)

• Connection group: Dyn11

• Cooling method: ONAN oil-immersed self-cooling

• Rated power: 10KVA-5000KVA

• Energy efficiency class: high-efficiency and energy-saving transformer

• Impedance voltage: 4%

 3. Key features

1. Ultra-low losses: Long-term operation significantly reduces electricity costs and ensures a quick return on investment.

2. Extremely low operating noise: The iron core uses multi-step joints and an optimized magnetic circuit, ensuring minimal vibration and low noise levels, meeting the quiet requirements of residential areas, schools, hospitals, and other environments.

3. Fully sealed, maintenance-free design uses 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. Thanks to the robust coil construction and stable insulation, it demonstrates strong short-circuit resistance, withstands power grid surges and load fluctuations, ensuring safe and reliable operation.

5. Long service life with a rational heat dissipation system, corrosion resistance, and weather resistance, with an overall service life of over 20 years and a low failure rate.

6. Compact design with easy installation, small size and light weight, suitable for various installation scenarios, including outdoor platforms, distribution rooms, and box-type substations.

4. Application scenarios

• New construction and energy-saving modernization of urban and rural power grids • Residential communities, schools, hospitals, office buildings, and commercial complexes • Continuous power supply for industrial facilities such as factories, mines, and industrial parks • Power supply for municipal infrastructure, water conservation projects, transportation systems, and telecommunication networks • Box-type substations, photovoltaic/wind power generation facilities, and temporary construction power supply
