introduction of 10kV Liquid-Immersed Totally-Enclosed Distribution Transformer
Designed specifically for the construction and renovation of urban and rural power grids, the core and windings are immersed in insulating oil, and heat is dissipated through the circulation of the oil. A sealed box is used to isolate external impurities, and advanced low-loss technology is applied, resulting in significant energy-saving effects.
Application: Ideal for residential areas, commercial buildings, industrial zones, and municipal infrastructure.

Liquid-Immersed Totally-Enclosed Distribution Transformer Features
Energy-saving, good electrical and mechanical performance, stable and reliable operation. The totally-enclosed structure delays the deterioration of oil quality and the aging of insulation.
Liquid-Immersed Totally-Enclosed Distribution Transformer Classification
The cooling method is liquid-immersed; the voltage regulation method includes non-excitation voltage regulation type.
Technical Parameters

After-sales Service
Installation and Commissioning: Dispatch professional technicians to provide on-site guidance, strictly control the installation process, and ensure that the equipment is put into use after the operating parameters meet the standards.
Maintenance and Repair: Develop a regular maintenance plan, covering equipment cleaning, component inspection, insulation and oil quality testing, etc., and handle failures in a timely manner.
Technical Support: Provide technical consultation and training to help users master equipment operation and maintenance skills and solve technical problems.
Spare Parts Supply: Establish a sufficient spare parts warehouse, respond quickly to supply demands, and shorten equipment downtime.
What is a liquid immersed transformer?
A liquid-immersed transformer consists of a magnetic core and coil assembly immersed in a fluid, normally mineral oil. The fluid must possess both good heat transfer characteristics and electrical insulating characteristics. An advantage of a liquid-immersed transformer is that it permits compact design.
What is the difference between encapsulated and non encapsulated transformers?
The encapsulated isolation transformer has its windings covered in heat-cured epoxy resin to reduce noise and prevent ingress of moisture and dust. Where for the non-encapsulated model has visible bare windings which are subject to dust and moisture.
What are the different types of liquid filled transformers?
Substation Liquid Filled Transformers
The transformers are offered with one of 3 different fluids: Mineral oil, silicone transformer oil, and Less Flammable Seed oil. Primary voltages from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes, 600 volt through 35 kV secondary voltage ratings are available.
