The transformer adopts a fully oil-immersed sealed structure, and its oil capacity will change with the change of temperature and load, which is completely adjusted by the flexible design of the transformer oil tank. It has strong anti-lightning and anti-short circuit performance, the energy-saving effect is more significant, and the size of the transformer is smaller.

Product features:

1. Low noise: compact structure, using new materials and new technologies to reduce noise, no oil storage tank, lower height than similar products. The oil does not need to be changed within the normal service life, and the safety and reliability of the operation of the power grid are improved.

2. Reliable long-term service life: The shell cover of the fully sealed transformer is connected with the edge of the oil tank by bolts or welding to isolate the contact between oil and air. The insulation material will not be affected with damp, which greatly reduces the aging speed of insulation and improves the service life.

3. Compact size and beautiful appearance.

4. No suspension iron core: Users do not need to check the suspension iron core before the operation of the fully sealed transformer, thus saving the cost of suspension iron core inspection.

5. Maintenance-free: The fully sealed transformer requires no maintenance.
