Two-Column Horizontal Rotary Disconnectors RD-220

The RD-220 disconnectors are designed for switching and isolating de-energized sections of AC circuits at 50 Hz with a nominal voltage of 220 kV, providing a visible break and grounding via stationary grounders. Key features include a self-cleaning multi-point contact system ensuring reliable current transfer with minimal resistance throughout the disconnector's lifespan. The RD-220 is equipped with a control cabinet featuring a monitoring and control system compliant with IEC 61850 standards.
