Disconnect Switch DS -10/630
The disconnect switch DS-10/630 is designed for repeated switching without load of sections of three-phase current circuits with a voltage of 6 (10) kV, frequency of 50 Hz, and grounding of disconnected sections using grounding knives.
The disconnect switch is installed in:
- complete transformer substations;
- one-sided serviceable assembly chamber;
- complete distribution device.
Disconnecting Switch DS-10/630 is a three-pole switch of the vertical-break type, consisting of:
- frame with insulators;
- current-carrying contacts;
- one or two grounding knives;
- manual drive.
The stationary contacts from the copper busbar (plug connection and non-plug hinge connection) are mounted on insulators installed on the switch frame. Also, the frame is equipped with a drive shaft, grounding knife, and other switch components.
The movable contact knives are connected to the stationary contacts through a hinge connection.

Load Break Switch LBS-10/630
The LBS-10/630 load break switches with grounding knives are designed for switching under load of sections of three-phase current circuits with a voltage of 6 (10) kV, frequency of 50 Hz, and grounding of disconnected sections using knives.
The load break switch is installed in:
- Complete Transformer Substation;
- Prefabricated chamber of unilateral service;
- Pole-mounted Outdoor Device.
LBS switches are equipped with an auto-gas arc extinguishing device. The arc is extinguished by the gas flow released from the walls of the arc extinguishing chamber when the arc affects them.
Control is carried out by a separate drive associated with the load break switch, which is mounted at the installation site of the switch. Drive type: spring (manual) or electric drive.
