S9/12KV Oil-immersed transformer
Product Features:
S9/12kv fully sealed oil-immersed power transformer has the
advantages of low loss, low noise and high efficiency, which can
achieve good energy saving effect and reduce pollution.Fully sealed
transformer and ordinary oil-immersed transformer, the elimination
of the oil tank, the change of oil volume by the elastic corrugated
tank to automatically adjust compensation, transformer and air
isolation, prevent and slow down the deterioration of oil and
insulation aging, enhance the reliability of operation, normal
operation without maintenance.

Structural characteristics
1. The transformer core is made of imported high-quality
cold-rolled silicon steel sheets, which can greatly reduce the
no-load loss and no-load current, and tie the core to ensure the
compacting degree of the core and reduce noise.
2. The high-low voltage winding is made of oxygen-free copper, and
the low-voltage winding of 500kVA and below adopts double-layer
cylindrical structure.The 630kVA and above adopts double or four
helix structure, and the high-voltage winding adopts multi-layer
cylindrical structure.
3. The transformer connection group adopts Dyn11 to reduce the
influence of harmonics on the power grid and improve the power
supply quality.
4, the transformer is a fully sealed structure, the inner and outer
surface of three primers, one coat of finish coating, the product
has anti-salt fog, anti-heat and humidity, anti-mold, beautiful and
durable, enhance the reliability of operation
