Product introduction

The fully sealed power transformer cancels the oil storage cabinet, and uses the fin plate of the corrugated oil tank body as the cooling element for heat dissipation, while expanding and contracting with the increase and decrease of transformer oil, which isolates the inside of the transformer from the atmosphere, prevents the deterioration of oil and insulation from moisture and aging, and enhances the reliability of operation.

The core adopts high-quality cold-tied silicon steel sheet, which effectively improves the distribution of magnetic flux density inside the core, reduces noise and loss. The coil is made of high-strength enameled wire (or paper-wrapped wire), with round simple (or pie) structure, even distribution of turns and reasonable insulation structure, which has strong short-circuit resistance.

The fasteners used in the oil tank are used to stop the nut, can ensure that the long-distance transport after the operation does not come loose. The surface of the tank is treated with phosphate and then painted with three anti-varnish (moisture-proof, mold-proof, salt spray-proof), which is widely used in the harsh environment of gold, ore, petrochemicals, etc.

Product Features

Energy saving: S11 type than GB/T6451 no-load loss is reduced by 30% on average, load loss is reduced by 25% on average, running cost is reduced by 20% on average.

Long service life: transformer oil tank with fully sealed structure, oil tank and box along the available bolt coupling or welded, transformer oil does not contact with air extended service life.

High operational reliability: Oil tank sealing related parts are improved to increase the reliability, improve the level of technology to ensure the reliability of the seal.

Small footprint: S11-M series transformer oil tank adopts corrugated plate type radiator, when the oil temperature changes the corrugated plate thermal expansion and contraction can replace the role of oil storage cabinet, corrugated plate type oil tank is beautiful in appearance, small footprint.
