External Installation Disconnector RD 110/2000-UHL1

External Installation Disconnectors RD 110/2000-UHL1 are intended for the activation and deactivation of disconnected parts of the electrical circuit which are under the voltage of up to 110 kV, as well as for the earthing of disconnected areas by means of earthworks forming an integral whole with disconnectors


External Installation Disconnectors RD 110/2000-UHL1 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.

*MD – manual drive
