Product Overview
- Traction-specific design: optimized for railway and metro traction rectification systems, withstanding frequent starts/stops and impact loads.
- Epoxy casting structure: epoxy resin cast molding delivers high mechanical strength with superior vibration and impact resistance.
- Optimized harmonic filtering: supports 24-pulse rectification and other schemes to reduce harmonic injection and improve grid-side power quality.
- Lower non-characteristic harmonics: design optimized for non-characteristic harmonic suppression, effectively reducing interference and additional loss risks.
- Class F insulation system: Class F insulation materials provide ample thermal margin for more reliable long-term operation.
- Controllable temperature monitoring: embedded PT thermistors enable real-time temperature measurement linked to alerts for finer temperature control.
Product Features
Superior overload capability
Stronger overload capacity withstands loads above the rated load for short periods, ensuring stable operation under high-load conditions.
Low Partial Discharge, Low Losses, High Efficiency
The transformer features low partial discharge and low energy loss, ensuring higher operating efficiency and reducing energy waste.
Zero fire hazard
Non-combustible winding insulation materials mean the transformer poses virtually no fire hazard, making it ideal for indoor installation and ensuring a safe operating environment.
Suitable for Outdoor Installation
Can be installed in an IP45-rated protective enclosure and used outdoors, with good dust and water resistance to adapt to harsh weather conditions.
Non-hygroscopic
The transformer uses moisture-proof, non-hygroscopic materials to prevent moisture from affecting performance, suitable for humid environments and ensuring long-term stable operation.
Vibration- and shock-resistant
Optimized for traction start-stop and braking impact conditions, with a more robust structure and more stable operation
