1250kVA 35 KV Oil Immersed Transformer

Oil Immersed Transformer,Hermetically Sealed Oil Filled Transformer,Immersed Transformer,Oil Filled Distribution Transformers,Power-Saving Oil-Immersed Transformer,

Product features:

1, the coil is wound by copper wire or foil, reinforced by glass fiber, epoxy resin without filling vacuum drying degassing dehumidification overall pouring, high mechanical strength, short circuit resistance, strong impact resistance.

2, the first end of the high voltage winding and the middle tap are embedded with copper insert structure, good steel, easy to adjust, and neat.

3, the iron core is made of high-quality grain orientation cold rolled silicon steel sheet stack, 45 degrees full slope multi-step joint. The surface is covered with resin edge coating, which is resistant to moisture, rust and noise.

4, the core, the clamp and the coil between the elastic clamping, so that the coil in a stable state of compression, to reduce noise.

5, transformer according to self-cooling design, the whole cast of high (low) pressure coil cylinder wall reserved longitudinal ventilation, can be equipped with forced air cooling device (cooling fan), the use of forced air cooling device, can increase the output capacity of 20%.

6. Equipped with a temperature controller, platinum resistance (Pt100) is placed in the embedded hole at the top of the low-voltage coil. It can monitor the temperature rise of the transformer winding group, automatically start and stop the cooling fan, and has the functions of fault alarm, overtemperature alarm and overtemperature trip, which provides a reliable overload protection device for the Dry Transformer, so as to improve the safety of the dry transformer operation.
