RDZ-35 series outdoor disconnectors for 35 kV
RDZ-35/1000 NF1 series AC disconnector with two non-conducting mounting posts, with PR-NF1 type drive, is designed for closing and opening electrically dead high-voltage electric circuit sections of 35 kV and commercial frequency of 50 Hz as well as for grounding deenergized sections by using stationary grounding blades (if available).
Climatic category is UKhL according to GOST 15150 (NF according to IEC); placement category is 1 according to GOST 15543.1 for the disconnectors of IP00 protection rating according to GOST 14254-96. The disconnectors of this series are made in single-pole, two-pole, and three-pole versions. When mounting, the disconnectors can be joined into one three-pole, two-pole or single-pole apparatus controlled by one drive. The connection of the driving disconnector with the drive, driven disconnectors is performed by using component parts on the mounting site. The delivery package does not include: frame and connecting rods; shafts between the poles and between the master pole and the drive.
Disconnector design is broken down as follows:
- according to the number of poles controlled by a single drive;
- according to the availability of grounding conductors
- according to the insulation type;
- according to the drive type.
