10kV-35kV Low Loss Three Phase Oil Immersed Distribution Transformer
⇒ PRODUCT DESCRIPTION
Features
♦Good Economic Performance
The S11~S13 series products are based on the S9 series, the no-load loss is reduced by 30% on average, and the no-load current is reduced by 70%-85% compared with the S9 series.
♦Long Lasting
The transformer oil tank adopts a fully sealed structure. The oil tank and the tank edge can be connected by bolts or welded to death. The transformer oil does not come into contact with the air, which prolongs the service life.
♦High Operational Reliability
The relevant parts of the fuel tank seal are improved to increase the reliability and improve the technological level to ensure the reliability of the seal.
♦Small Footprint
S11-M, S13-M series transformer oil tank adopts corrugated plate radiator. When the oil temperature changes, the corrugated plate thermal expansion and contraction can replace the role of the oil conservator. The corrugated plate oil tank has a beautiful appearance and small footprint.
