Product Details

Performance Characteristics of 35KV Grade Oil-immersed Transformer S11-630~31500/35:

1, The oil-immersed transformer low-voltage winding in addition to small capacity using copper wire, generally use copper foil around the shaft of the cylinder structure, high-voltage winding using multi-layer cylinder structure, so that the winding of the safety balance, small leakage, high mechanical strength, strong ability to resist short circuit.
2, Iron heart and winding each adopted fastening measures, machine height, low-pressure lead and other fastening parts are self-locking anti-loose nuts, the use of non-hanging structure, can withstand the shock of transport.
3, Coil and iron core using vacuum drying, transformer oil using vacuum filter oil and oil injection process, so that the transformer internal moisture to minimize.
4, The tank using corrugated, it has a breathing function to compensate for the change in the volume of oil caused by temperature changes, so the product does not have a storage tank, obviously reduce the height of the transformer.
5, Because the corrugated plate replaced the oil storage cabinet, so that transformer oil isolated from the outside world, which effectively preventtheentry of oxygen, water and lead to a decline in insulation performance.
6, According to the above five points of performance, to ensure that the oil-immersed transformer in the normal operation does not need to change oil, greatly reducing the maintenance costs of the transformer, while extending the life of the oil-immersed transformer.
Temperature Environment for 35KV Grade Oil-immersed Transformer S11-630~31500/35:
1, At 220 degrees C temperature, the oil-immersed transformer to maintain long-term stability.
2, At 350 degrees C temperature, the oil-immersed transformer  can withstand short-term operation.
3, In a wide range of temperature and humidity, to maintain stable performance.
4, At a temperature of 250 degrees C, the oil-immersed transformer  will not melt, flow and fuel.
5, At a temperature of 750 degrees C, the oil-immersed transformer  will not release toxic or corrosive gases.
