The 80kVA Oil Immersed Transformer is a sealed power conversion device constructed with a cold-rolled silicon steel core and oxygen-free copper windings. It features a spiral coil design with longitudinal oil channels to enhance internal heat dissipation. A short-circuit-resistant structure strengthens end supports to protect against transient current surges. A dedicated lifting mechanism and positioning system ensure transport stability.
The 80kVA Oil Immersed Transformer can be used in urban power distribution systems to withstand daytime load fluctuations, and oil-immersed heat dissipation ensures continuous full-load operation. Its corrosion-resistant structure effectively blocks salt spray corrosion in humid coastal areas.
The reinforced insulation oil gap design for high-altitude areas reduces the risk of low-pressure discharge.

Dissolved gas components are regularly analyzed by chromatographic analysis, and internal fault diagnosis is activated when acetylene concentrations are abnormal. The oil level is monitored using a two-color window indicator, and an emergency alarm is triggered when the oil level drops suddenly. Annual oil dielectric strength testing is performed, and vacuum oil filtration is performed when the breakdown voltage falls below the threshold.
Prolonged operation below a specific load rate resulted in low oil temperature in an 80kva Oil Immersed Transformer, leading to water analysis and reduced insulation strength. Regular full-load heating is required to maintain water solubility in the oil. Automatic heating should be activated during winter shutdowns to maintain oil temperature.
Immediately perform a winding deformation frequency response test and compare it to a reference spectrum. Check the displacement of the hold-down bolts by hanging the cover, and use a laser rangefinder to verify axial dimensions. Perform a no-load test to monitor for abnormal vibration harmonics. If the core is grounded at multiple points, dismantle and repair the insulation.
