The 315kVA premium oil-immersed transformer with on-load tap changer (OLTC) is developed for urban distribution networks and factory expansion projects that require real-time voltage adjustment and stable power quality.
With a refined magnetic core, copper winding system, and integrated OLTC mechanism, it enables smooth voltage regulation without interrupting operation, supporting consistent output under varying grid conditions.
This model is suitable for city power networks, industrial upgrades, and load expansion scenarios where voltage stability and operational continuity are essential.
Integrated OLTC system allows voltage regulation during operation, supporting continuous power supply without interruption.
Designed to maintain consistent voltage levels during factory expansion and load increase scenarios.
Supports fine voltage adjustment to match changing grid conditions in urban environments.
Optimized structure suitable for limited installation space in city distribution networks.
Balanced electrical and thermal design supports stable performance under fluctuating load and grid conditions.
