Outdoor substations, industrial parks, mines, urban and rural power grids.
GB1094, GB/T6451
1. Good economic performance: The average no-load current decreases by 60% to 80%, and the average no-load loss decreases by 25% to 35%.
2. Long service life: The transformer oil tank adopts a fully sealed structure, and the oil tank can be bolted or welded to the edge of the tank. The transformer oil does not come into contact with air, which extends its service life.
3. High operational reliability: Improvements have been made to the sealing components of the fuel tank to increase reliability and improve the level of craftsmanship to ensure the reliability of the seal.
4. Small footprint: The transformer oil tank adopts a corrugated plate radiator, which can replace the role of the oil storage tank when the oil temperature changes due to thermal expansion and contraction of the corrugated plate. The corrugated plate oil tank has a beautiful appearance and a small footprint.
