The P-94 switch-disconnectors are designed for overhead distribution networks (up to 36kV). They allow isolating a part of the network after the appearance of a permanent fault or enabling interventions downstream on the line.
- Material for outdoor use
- Simple and robust construction
- Large isolation distance
- Significant creepage distance
- Good performance against short-circuit currents
- Perfect visibility in the open position
