Performance

1. Safe and Reliable: They use efficient insulation protection and heat dissipation equipment, with a well-designed cable cabinet structure ensuring safety and reliability. They have a strong overload capacity, allowing for 2 times overload for 2 hours and 1.6 times overload for 7 hours without affecting their lifespan.
2. Convenient Connections: The use of elbow plugs makes it easy to connect high-voltage incoming cables, allowing for plug-in and plug-out operations under power.
3. Strong Defense Capability: They can effectively resist instantaneous voltage peaks, protecting power equipment from damage. They also feature double fuse protection:Insertion Fuse (BAY-o-NET): A dual-sensitive fuse (temperature and current) protecting against short-circuit faults on the secondary side.Backup Current Limiting Protection Fuse (ELSP): Protects against faults inside the transformer and the high-voltage side.
4. Flexible Power Supply: They can be either terminal type or ring network type, allowing one transformer to supply power to another, enhancing power supply distance and reliability.
5. Energy Saving and Environmental Protection: Designed with energy efficiency and environmental protection in mind.
