Product Description

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.

Technical data

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
