Oil-immersed transformers product features:
a, oil-immersed transformer tank by corrugated films, with respiratory function to compensate for oil volume changes caused by temperature changes, so it doesn't have the oil tank, apparently reduces the height of the transformer.
b, oil-immersed transformers due to the corrugated plate replaces the conservator, the isolated transformer oil, thus effectively prevent the oxygen and moisture insulation performance degradation caused by entering.
c, oil-immersed transformer based on these five properties, ensure that the oil-immersed transformers during normal operation does not need to change the oil, significantly reduces transformer maintenance costs while extending the life of the transformer.
d, oil-immersed transformer low voltage windings apart from small-capacity copper wires, usually adopted copper foil around the cylindrical structure high voltage winding using multi-layer cylindrical structure, distribution to winding ampere balance, low magnetic leakage, high mechanical strength, ability to withstand short circuit.
e, oil-immersed transformer core and winding respective tightening measures have been adopted, height, both the fastening parts such as low-voltage wire with self-locking nut, not hanging heart structure can withstand the shock top transport.
f, oil-immersed transformer coil and core adopted vacuum dryness, transformer oil vacuum oil filter and the oil processing, internal moisture to a minimum.
