Russian type composite switch

Disconnector RLND-1-10 II / 400 UHL1 is used in the repair and prevention of high-voltage

electrical networks or electrical equipment with a voltage of 10 kV, providing safe removal of

voltage from previously de-energized consumer circuits, while all disconnected consumer circuits

are effectively grounded.

RLND-1-10 II / 400 is indispensable for:

- turning on and off the voltage of de-energized sections of the high voltage electrical circuit;

- the presence of a visible compartment of electrical equipment, in which there is a need for

protected equipment or equipment repair;

- turning on and off idling current for sugar transformers;

- grounding de-energized fragments of the circuit using stationary grounding conductors
