Drawings & Dimensions
technical features
- Vacuum Resin Casting
Coils undergo class-H vacuum epoxy casting to eliminate internal voids and block coastal moisture ingress.
- Core Surface Protection
Core laminations receive multi-layer anti-salt hydrophobic coatings to block salt-spray water film formation.
- Anti-Corrosion Hardware
Fasteners and clamps utilize high-grade stainless steel or hot-dip galvanized coatings to resist severe marine and coastal corrosion.
- Precision Thermal Modeling
Thermal CFD simulations optimize internal cooling ducts to prevent localized hotspots under peak load.

Quality Control & Testing
- Winding Insulation Strength
Megohmmeter testing confirms insulation resistance exceeds 2000 MΩ, preventing dielectric breakdown under stress.
- Voltage Conversion Precision
Ratio bridge verification limits actual deviation within ±0.5%, ensuring highly accurate voltage output.
- Short-Term Overvoltage Endurance
Power frequency testing applies 1.5 times rated voltage for 1 minute without breakdown.
- Low Partial Discharge
Factory routine testing limits partial discharge below 10 pC to extend long-term dielectric life.
- Strict Loss Verification
Rigorous load and no-load core testing ensures the 2000KVA Dry Type Transformer meets energy efficiency standards.
- Protection Device Responsiveness
Simulated fault testing verifies that PT100 sensors and temperature controllers trigger instantly.

FAQ
Q: How does the enclosure design prevent accidental human contact during operation?
A: Enclosures feature built-in safety interlocks and standardized mesh screens to block foreign objects and prevent accidental contact.
Q: How are units secured inside shipping containers to prevent shifting during transit?
A: Heavy-duty steel structural bases are bolted directly to the container floor using high-tensile steel tie-rods and chocks.
Q: Can the factory install pre-wired terminal blocks for secondary control wiring?
A: Yes, all secondary control and sensor wiring can be routed to a centralized, accessible low-voltage terminal box.
