Energy - saving: Compared with the original S9, the no - load loss is reduced by an average of more than 29.25%, the no - load current is reduced by more than 37.9%, and the operating cost is reduced by an average of more than 18.9%.
Long service life: The transformer oil tank adopts a fully sealed structure. The oil tank and the tank edge can be connected by bolts or welded. The transformer oil does not contact with air, which prolongs the service life.
High operation reliability: The components related to the oil tank sealing have been improved, which increases reliability. The process level is improved to ensure the reliability of sealing.
Small floor area: The fully sealed transformer oil tank adopts a corrugated radiator. When the oil temperature changes, the thermal expansion and contraction of the corrugated plate can replace the function of the oil conservator. The corrugated plate oil tank has a beautiful appearance and a small floor area. The three - phase oil - immersed power transformer adopts a new insulation structure, which improves the short - circuit resistance. The iron core is made of high - quality cold - rolled grain - oriented silicon steel sheets; the high - voltage and low - voltage windings are made of high - quality oxygen - free copper wires and adopt a multi - layer cylindrical process structure; all fasteners are treated with special anti - loosening, and have high mechanical strength. The corrugated oil tank shell adapts to the expansion of oil with its own elasticity. It is a permanently sealed oil tank and has been widely used in various power distribution equipment.
