Disconnector RD(Z)-110/1600

1401000
Disconnectors of the RDZ series for 110 kV are designed to switch on and off de-energised sections of the electrical circuit under voltage, transformer no-load currents, charging currents of overhead and cable lines, as well as grounding of disconnected sections using grounding devices.
Disconnectors are available in single-pole, two-pole and three-pole versions. The pole to which the actuator is connected is the leading pole. The actuators are designed to operate the disconnectors. The drive shafts of the main circuit and the earthing circuit are rotated
- manually, using PR-2B, PR-90/180 drives (or analogues);
- automatically, using PD-14 motor drives (or analogues).

The disconnectors are designed for operation in the following conditions:

– altitude up to 1000 m above sea level

– ambient temperature from minus 60 to plus 40°C;

– average annual relative humidity of 80% at a temperature of plus 15°C;

– maximum wind pressure of 700 Pa (corresponds to a wind speed of 34 m/s) in the absence of ice;

– maximum wind pressure of 140 Pa (wind speed of 15 m/s) in case of ice crust formation on the surface up to 20 mm thick.

– the maximum total mechanical load on the outputs of one pole (from the wires connected taking into account wind loads and ice formation) is 1000 N, provided that it is evenly distributed at the outputs.

The disconnectors are not intended for operation under strong shaking, vibration, or shock.
