Supplier From China
Jun-18-18

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.

Power Transformer (35kV)
Oil-immersed Transformer
Products structure and technical features
The oil-immersed transformer produced by our factory have these advantages: low loss, low noise, high short circuit strength and good appearance. We company create these prefect products of that each parameter has reached to advanced level among domestic similar products by combining advanced manufacture equipments and technology.

Structure features:
Core and main body: it is used iron core cutting line ,all inclined ladder joints and improving flux trend to eliminate flux saturation phenomenon of iron core in joints . By doing these, it reduces the no-load loss, no-load current and noise of transformers. Adopting pulling-plank structure, in order to strengthen the ability of withstanding short-circuit, we put many nails around pressing planks and bracing plates are used as support between H.V and L.V yoke, make the iron core be a whole. The iron core sheet are coated by glue which are specialized for silicon steel , so that all silicon steels can be bonded together to make the iron core be  integral one, this effectively enhances mechanical strength and plays a positive role in the core anti-rust. The low part of the body and the oil tank are supported through bracing plates adopt" high intensity electric laminated" technology, to guarantee the low part of oil-immersed transformer's body safe and reliable.

Coil: The high-voltage(HV) coil adopts an interleaved-continuous structure, The low-voltage(LV) coil adopts an interleaved-continuous or spiral structure, are independently provided with voltage-regulating winding to balance the ampere turn of each winding-up, effectively lower the mechanical force to minimal level. In the transformer winding, there is a zigzag oil guide structure so as to fully cool all areas inside the winding, lower the temperature rise of the winding and the hot points of the winding and prolong the service life of insulation.

Oil tank: the tank's structure of oil-immersed transformer is bell jar type or suspended type, have a good looking and high mechanical strength. It adopts" flanged joint" technology in every key point (such as annular tubes, pressure valves, switches,etc.), which effectively avoid leaking oil.
