Product description
S13 oil-immersed transformer is a wide range of power facilities with a wide range of types, which is of great significance for energy conservation and emission reduction. S11 fully sealed oil-immersed power transformer is the main selection product of power distribution equipment, and the energy saving effect is remarkable. Sales Hotline: 13508930968
At present, the mainstream S13 oil-immersed transformer generally uses S11 laminated core power transformer. Adopting the full oil-filled sealed type, no oil conservator, corrugated sheet box structure, the transformer due to the change of temperature and load caused by the change of oil temperature and volume, completely regulated by the corrugated oil tank, its no-load loss is reduced by 25% compared with S9, the lightning impact resistance and short circuit resistance is strong, the energy-saving effect is obvious, and the appearance size of the transformer is reduced. The S11 transformer is produced with high permeability oriented silicon steel sheet with a thickness of 0.27-0.30mm and a unit iron loss of 1w/kg, while the new S9 type is an ordinary silicon steel sheet with a thickness of 0.30-0.35mm and a unit iron loss of 1.20-1.55w/kg.
The S13 oil-immersed transformer produced by our company uses all 30P series high magnetic permeability oriented silicon steel produced by Shanghai Baosteel, adopts foil winding coil and new insulation materials and processes, and the product is resistant to high temperature, impact resistance, and fully sealed structure design to ensure the stability of transformer oil quality and extend the maintenance cycle.

Performance characteristics:
S13 oil-immersed transformer capacity range of 20kVA~3150kVA, in 10KV, 50HZ transmission and distribution system, can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, oil production platforms, especially suitable for flammable, explosive and other places with high fire requirements and harsh environment. It can also be used for residential areas, commercial streets, industrial and mining enterprises, and rural power and lighting.
Long service life and maintenance-free operation. The fully sealed transformer cover and the edge of the box are bolted or welded to isolate the contact between oil and air, and the insulation will not be damp, which greatly reduces the aging rate of insulation and improves the service life.
The design is compact and the operating noise is low. Due to the use of new materials and new processes, noise is reduced, there is no oil conservator, and the height is lower than similar products. There is no need to change the oil during the normal life cycle, which improves the safety and reliability of the operation on the network.
The corrugated fuel tank is small in size and beautiful in appearance. The oil tank of S11 power transformer adopts corrugated sheet type heat dissipation, and when the oil temperature changes, the change of oil volume is adjusted and compensated by the elastic expansion and contraction of the corrugated sheet.
No core and oil testing. When the transformer is encapsulated, the vacuum filtration oil injection process is used to completely remove the moisture in the transformer oil. After sealing, the inside of the transformer is not in contact with air, which effectively prevents oxygen and moisture from entering the transformer and causing the insulation performance to deteriorate.
