The transformer core is made of imported high-quality cold-rolled silicon steel sheet, which greatly reduces no-load loss and no-load current. The core is tightly bound to ensure the compactness and reduce noise. *� The high and low voltage windings are� made of oxygen-free copper. The low voltage winding of 500KVA and below is of double-layer cylinder structure, of 630kVA and above adopt double helix or four helix structure. High-voltage winding adopts multi-layer cylinder structure. Dyn11 is used in the transformer connection group to reduce the influence of harmonics on the power grid and improve the quality of power supply. *� The transformer is a fully sealed structure, with three coats of primer and one coat of finish paint applied on the inner and outer surfaces. The product is salt fog proof, moisture proof and fungus-proofing, beautiful, durable and reliable The measured noise value is lower than the standard and maintenance free under normal operation.

Dry type transformers shall be installed in accordance with the manufacturer's requirements, and shall be equipped with temperature measuring devices, generally 630kVA and above transformers. A,1000kVA and above oil-immersed transformer shall be equipped with an outdoor signal thermometer and can take distant signals. Product features: A, tank using corrugated sheet, it has the respiratory function to compensate for temperature change caused by the oil volume change, so the product without oil storage tank, obviously reduce the height of the transformer. B, because the corrugated film replaces the storage tank, the transformer oil is isolated from the outside, thus effectively preventing the entry of oxygen and water and the decrease of insulation performance. C, according to the above five performance, to ensure the oil-immersed transformer within the normal operation of the don't need an oil change, greatly reduces the maintenance cost of transformer, and prolong the service life of the transformer. D. In addition to the small capacity of copper wire, copper foil is usually used in the cylinder structure. The high voltage winding adopts multi-layer cylindrical structure to balance the ampere-turns distribution of the winding, the leakage is small, the mechanical strength is high, and the anti-short circuit capability is strong. E, iron core and winding each adopt the fastening measure, the height of the device, the low voltage lead wire and other fastening parts are equipped with self-locking anti-loose nuts, adopt the non-lifting structure, can withstand the shock of transportation. F, coil and iron core adopt vacuum drying, the transformer oil adopts vacuum filter oil and oil filling process, which minimizes the moisture in the transformer.
