- RNO 12-36
RNO family type disconnectors are factory-manufactured and tested devices for visible separation from under voltage parts at medium voltage overhead lines.
They are designed and manufactured in accordance with MKS and 1ES standards.
RNO type disconnectors are used to provide visible insulation distance to medium voltage aerial lines when they are in a no-voltage state.
Silicone insulators are installed as insulation. They are intended for horizontal and vertical mounting.
They are produced in the following variants :
| 12 kV | 24 kV | |
| RNO 12/630-400 | RNO 24/630-400 | plain with a spring |
| RNO 12/630-400-UH | RNO 24/630-400-UH | substation |
| RNO 12/630-400-ET-VT | RNO 24/630-400-UH | with grounding blades |
- RNO 6 12-24
RNO b type disconnectors are used to provide visible insulation distance to aerial power lines when they are in a no-voltage state.
The full distance between these disconnectors is larger and can be adjusted, thus providing the required electrical range in the line spans.
As insulation, silicone insulators are installed, intended for horizontal mounting.

- RNO-K 12-24
RNO-K type disoconnectors are designed and manufactured in accordance with MKS and 1ES standards.
They are used for switching off - switching on the drive current and providing visible insulation distance at medium voltage overhead lines.
Chambers that work on the principle of a gas generator are used as a medium for extinguishing the electric arc.
Silicone insulators are installed as insulation. They are intended for horizontal and vertical mounting
