Features

Safe and compartmentalized:

Composed of a physically separate high-voltage chamber, transformer chamber, and low-voltage chamber, incorporating a reliable "five-prevention" interlock system to ensure operational safety.

Flexible HV switching:

High-voltage switches can be selected from fully insulated SF6 gas-filled cabinets, solid-insulated RMUs, and vacuum RMUs, with options for motorized operation and automation via DTU integration.

Versatile transformer options:

Transformers can be either dry-type or oil-immersed, characterized by low energy loss, low noise emission, low temperature rise, strong overload capacity, high short-circuit withstand capability, and excellent impact resistance.
