Disconnector
switch for railways
Hughes series of air break switches (disconnectors) were especially developed for railway, light rail and tram applications. They are built to remain in operation for more than 30 years without major maintenance. The models range for railways includes 1 pole, 1+1 pole and 2 poles versions. Together with our motor drives it provides a complete solution for automation and remote control of the railway and tram electrical networks.
- High quality mechanical parts
- Low life cycle cost
- High level of insulation
- Innovative design
- Silicone insulators
- Easy to remote control
1+1 POLE DISCONNECTORDESCRIPTION
