The high-voltage external connectors RND 35/1000-UHL1 at a rated voltage of 35 kV shall be used to activate and disconnect the energized areas of the high-voltage electrical circuits, as well as earthing of disconnected areas by means of grounding knives (if any).
RND 35/1000-UHL1 connectors have a single-pole, bipolar and three-pole design. The pole to which the drive is connected is the lead. The drives are designed to operate with disconnectors. The drive shafts of the main circuit and the ground collar are rotated manually, with the aid of the drives of the MD-2B or GDP-Y bipolar and three-pole disconnectors, the remaining poles are driven. The connection of the drive pole to the drive and the drive pole to the driven poles is carried out by the consumer when preparing the disconnector for use.
