Product overview

The fully sealed transformer is a transformer that is completely isolated from the outside atmosphere inside the oil tank. The outside moisture and oxygen cannot enter the oil tank, thus slowing down the aging speed of the insulating material and the oil, and greatly improving the reliability of the transformer operation.

features and advantages

  • More economical

By optimizing the design, the overall simple but not simple, fully functional but very competitive price, is a cost-effective product in power distribution.

  • More reliable

The low voltage adopts copper wire or copper foil, and the high voltage adopts the round-through structure of high-strength enameled wire or paper-coated wire. The ampere-turn is evenly divided, the magnetic flux leakage is small, the mechanical strength is high, and the short-circuit resistance is strong.

The iron core and coil are vacuum dried, and the transformer oil is vacuum oiling process, so that the micro water content in the transformer oil is reduced to a minimum.

All fasteners in the box are hot-dip galvanized non-return nuts, even if long-distance transportation will not loosen. All sealing gaskets are made of high quality acrylic rubber, which can effectively place light aging, electrical aging and thermal aging.

  • More efficient

According to the national standard requirements of energy efficiency grade design and production, can greatly reduce the empty load loss, improve operating efficiency.
