S-35kV series oil immersed transformers produced by the company is suitable for three-phase AC 50 / 60Hz, rated voltage 35kV distribution grid, and plays an important role in high-voltage transmission and low-voltage power supply. Products with high efficiency, low loss characteristics, can save a lot of power consumption and operating costs, social benefits, have been widely used in power plants, substations, industrial and mining enterprises, ports, airports and other places. With on load tap changer, the product can realize the function of manual or automatic voltage regulation without power failure, which is conducive to stabilizing the voltage of power grid in each load center and improving the quality of power supply.

Oil Immersed Type Transformers Characteristic
1. The coil adopts a low axial short-circuit force structure. When the transformers is short-circuited, it can greatly reduce the axial short-circuit force and greatly improve the ability of withstanding short-circuit.
2. All the bolts and nuts on the cover surface are made of 304 stainless steel, which enhances the rust prevention ability of the transformers.
3. Each sealing rubber ring adopts the best rubber material in China, which greatly prolongs the service life of the sealing rubber ring.
4. The transformer body adopts a high-reliability support structure to ensure reliable compression of the upper and lower parts of the coil. The entire body structure improves the ability of withstanding short-circuited.
5. This not only reduces the no-load loss of the transformers, but also ensures that the core flux is not saturated when the transformers is operating under voltage, so that the third harmonic of the transformer is small.
