High-voltage disconnectors RLNDz 10-400U1 and RVz 10-630 U3
High-voltage disconnectors RV are designed for switching on, long-term transmission, disconnection of three-phase currents of 400 or 630 A with a frequency of 50 Hz in electrical networks with an isolated neutral and an operating voltage of up to 12 kV in the absence of load current between electrical networks.
Climatic type U3 according to GOST15150.
Normal operation of load switches is ensured under the following conditions:
1. Altitude above sea level - no more than 1000 m;
2. The environment is non-explosive, not containing conductive dust, aggressive gases and vapors in concentrations that reduce the parameters of the KTP within unacceptable limits;
3. Atmosphere type - II according to GOST15150;
4. Ambient temperature – from -25°C to +40°C.
The main technical characteristics are given in the table.
