Fully Sealed Three-phase Oil Immersed Transformer

Fully sealed oil immersed transformer is a new generation of energy-saving distribution equipment, which uses transformer oil as insulation and cooling medium, adopts a fully sealed corrugated oil tank design, and is widely used in 10kV distribution systems to provide stable voltage conversion for various terminal loads.

Features
✅  Fully sealed structure: The fuel tank is completely sealed, isolating air, delaying insulation oil aging, and reducing maintenance workload in the later stage;
✅  Energy saving and low loss: using high magnetic conductivity silicon steel core, S11 and S13 models have lower energy consumption compared to older products, saving electricity costs for long-term operation;
✅  Low operating noise, good overload capacity, suitable for long-term continuous outdoor work;
✅  Simple and reliable structure, strong universality of accessories, and convenient maintenance;
✅  Compact footprint, can be directly installed in outdoor distribution areas and inside transformer boxes.

Advantage
Fully sealed and maintenance free
The sealed structure of the box prevents air and water vapor from entering, slows down the deterioration of oil quality, and significantly reduces daily oil sample testing and refueling work.
High Efficiency and Energy Saving
High quality cold-rolled oriented silicon steel sheets are used to manufacture iron cores, with excellent indicators of no-load loss and load loss, continuously reducing electricity costs.
Strong environmental adaptability
It can be installed outdoors, resistant to high and low temperatures, dust-proof, and can be independently installed outdoors or assembled inside a box type substation.
Complete safety protection
Equipped with pressure relief valve, high and low voltage insulation sleeve, temperature measuring device, with overload and fault pressure relief protection, ensuring high operational safety.
