Product Composition
Coil: Copper foil wound with epoxy resin vacuum casting for high mechanical strength and insulation performance.
Core: Cold-rolled silicon steel laminations reduce no-load losses.
Cooling System: Non-metallic fin-type heat exchangers enhance natural cooling efficiency.
Enclosure: Flame-retardant composite material encapsulation combines protection with lightweight design. All components comply with RoHS certification and international environmental standards.
Production Process
Precision Design: Customized 3D modeling and parameters based on customer load requirements.
Winding Process: Fully automatic CNC winding machines ensure coil consistency.
Resin Casting: Vacuum pressure impregnation (VPI) technology ensures bubble-free insulation layers.
Assembly & Testing: Precise alignment of cores and coils, passing partial discharge tests, temperature rise tests, and short-circuit endurance verification.
Factory Quality Inspection: 100% full inspection, providing type test reports and CE/ISO certification documents.

Maintenance Guidelines
1.Daily Maintenance
Monthly checks:
Inspect enclosure seal to prevent foreign objects from entering.
Check operating temperature (≤130°C) using an infrared thermometer.
Ensure unobstructed cooling channels and clean dust from the transformer.
2.Annual Maintenance
Insulation testing:
Measure winding-to-ground insulation resistance with a 2500V megger (should be ≥300MΩ).
Perform dielectric strength tests (AC withstand voltage 35KV/1min).
Load assessment:
Check three-phase current balance (deviation ≤5%).
Record temperature rise data and compare with historical data; if abnormal, inspect further.
3.Fault Handling
Abnormal vibration/noise:
Check for loose fasteners or improper core grounding.
Local overheating:
Likely caused by turn-to-turn short circuits; immediately disconnect power and contact after-sales support.
4.Precautions
Avoid frequent overload operation (suggested ≤1.2 times rated capacity).
Before restarting after long-term disuse, perform 24 hours of no-load preheating.
Always disconnect power and ground during maintenance to ensure operational safety.
Application Scenarios
Industrial Manufacturing: Factory power systems and production line equipment power supply.
Energy Infrastructure: Wind farms, photovoltaic power stations, and grid-connected equipment.
Urban Infrastructure: Metro, high-speed rail traction stations, and substations.
Commercial Buildings: High-end office buildings, hotels, and data centers.
Special Environments: Underground substations, mines, chemical plants (explosion-proof scenarios).
