Oil Immersed Cooling Oil For Heat Dissipation
Transformer oil possesses exceptional insulation capabilities, ensuring robust insulation safeguards between windings and their enclosures, thereby mitigating the risks of electrical shocks and equipment damage.
Product Details：Oil Immersed Cooling Oil for Heat Dissipation
By actively absorbing moisture from the atmosphere, transformer oil creates a protective shield that keeps moisture at bay from entering the transformer, crucial for safeguarding the iron core and windings against corrosion and short circuits. Furthermore, it meticulously separates moisture from the oil's other constituents, maintaining oil stability and preventing emulsification.
