Application fields
Widely used in power plants, power grids, petrochemicals, metallurgy, industrial and mining enterprises, urban infrastructure, such as airports, subways, docks and residential areas.
Technical features
The low-voltage winding can be wound in foil, which has a compact structure and reduces the radial force during short circuit, greatly enhancing the ability to resist sudden short circuits.
The box adopts a fully sealed corrugated oil tank structure to prevent air and moisture from contacting the transformer oil, reduce the degree of oil aging, and extend the service life of the transformer; the volume change of the transformer oil due to thermal expansion and contraction is adjusted through the elastic deformation of the corrugated sheet.
The product is an outdoor structure with a high anti-fouling grade and good heat dissipation; there is no need to replace the transformer oil during normal use, which is truly maintenance-free and ensures the safe operation and reliability of the power grid. 5. The transformer is equipped with a pressure release safety protection device. When the transformer fails and the pressure is too high, it can be released reliably and safely through the pressure release valve to prevent the expansion of the accident.
Product advantages
Good technical and economic performance, long service life, high operating reliability, and small footprint.
