STRUCTURAL COMPOSITION

The low-voltage winding of the oil-immersed transformer adopts copper foil winding or layer structure; the high-voltage winding adopts a multi-layer cylindrical structure, with balanced ampere-turn distribution, small magnetic leakage, high mechanical strength, and strong short-circuit resistance. LOW NOISE

The iron core is made of high-quality, high-magnetic silicon steel sheets and adopts a full-slant step-joint stacking machine type. The process is advanced, with low no-load loss and low noise. RELIABLE FASTENING

The body adopts fastening measures, and the fastening parts, such as the height and low-voltage leads of the body, are equipped with anti-loosening nuts. The non-hanging structure is adopted, and the long-distance transportation is also fastened and reliable. INSULATION PERFORMANCE

The coil and the iron core are vacuum-dried, and the transformer adopts the vacuum oil injection process, which makes the insulation strength of the oil-immersed transformer higher and the electrical strength higher. SAFE USE AND LONG SERVICE LIFE

Because the oil tank adopts a corrugated oil tank, the oil storage cabinet is eliminated, and the transformer oil is isolated from the outside world, which effectively prevents the entry of oxygen and moisture and causes the decline of insulation performance, truly realizing maintenance-free, greatly reducing the maintenance cost of the transformer, and at the same time extending the service life of the transformer.
