Medium voltage switch type RXD is:

• air-insulated
• metal-clad
• available in retractable or fixed version (depending on equipment)
• equipped with a unique bar system
• intended for nominal voltages of 12 kV or 36 kV
• designed for use inside

This switch offers:

• maximum performance encased in an air-insulated metal housing
• safe and efficient operation at voltages up to 36 kV
• ideal for use in transformer stations and power plants
• high configurability and possibility of expansion through additional modules
• retractable version that can include contactor, circuit breaker, voltage transformers with fuses

Increased safety is ensured by:

• retractable module maneuverable with the housing door closed
• internal spring-resistant housing
• door locks
• uninterrupted operation even during maintenance
