Industry pain points:
Traditional power distribution equipment is prone to poor heat dissipation, insulation aging, oil leakage and other faults under high temperature and high load, resulting in a surge in the risk of power outages and high maintenance costs14.
Your troubles: If the 20KV Oil Immersed Transformer frequently leaks oil or overheats, it will not only shorten the life of the equipment, but also threaten the safety of the power grid.
Our solution: Use a fully sealed corrugated oil tank and high-stability insulating oil, integrate an anti-short-circuit reinforced structure, and adapt to harsh working conditions. Actual effect: After the application of a charging station in a logistics park, the failure rate dropped by 60%, the no-load loss decreased by 30%, and the load loss decreased by 25%, supporting a 40% increase in the average daily charging volume.
Multi-dimensional application scenarios
As the core of Oil Immersed Transformer for Power Distribution, this product is suitable for:
New energy charging station: supports 2000kVA large capacity and ensures high-speed charging of multiple piles9;
Industrial power grid: withstands -30℃~40℃ temperature range, IP55 protection against dust and moisture8;
Offshore wind power: anti-vibration design prevents winding deformation and is suitable for deep sea scenarios6.
Safe and innovative underlying design
Oil Immersed Transformer Safety Features Focus on intrinsic safety:
Fully sealed and leak-proof: corrugated oil tank eliminates oil-gas contact, delays insulating oil degradation, and extends service life to 30 years58;
Active fault defense: real-time monitoring of gases such as acetylene (C₂H₂) and hydrogen (H₂), and early warning of discharge and overheating risks.
Product Features
Fully sealed and leak-proof design
Corrugated oil tank replaces oil storage cabinet, and oil volume changes and expands and contracts adaptively to prevent leakage.
Combined with 0.1mgKOH/g low acid value insulating oil, the breakdown voltage is ≥40kV/2.5mm85.
Multi-layer insulation protection system
The high-voltage winding is wound with oxygen-free copper wire drum, and the silicon steel sheet core is annealed and bundled. The no-load current is 20% lower than the national standard58.
Efficient heat dissipation structure
The oil circulation heat capacity reaches 2kJ/kg·K, and it can run continuously for 150 minutes with an overload of 20%, and the temperature rise is controlled to ≤85℃81.
Short-circuit resistant strong structure
Winding compression process + axial support bar, passed the 150kA short-circuit current test, and suppressed vibration deformation610.
Maintenance Tips
Oil chromatography analysis: Check C₂H₂ content every quarter. If it is >5μL/L, check for discharge1;
Infrared temperature measurement: When the temperature rise at the tap changer is abnormal, measure the DC resistance difference (threshold ±2%)10;
Oil level check: When the oil level is too low at low temperature, add oil to avoid winding exposure and breakdown1;
Annual inspection of seals: Replace oil-resistant rubber pads to prevent oil leakage from the box edge causing insulation degradation4.
The essence of Oil Immersed Transformer Applications is to make the power heart surge in silence
