High-voltage disconnector RLK-IV-10/400-PL-UHL1 (with drive) KEAZ 321802

RLK - break-make switches of the oscillating type, manufactured in a three-pole design. Each pole has two fixed columns installed on the frame and one movable column installed on a movable bracket that can oscillate in the direction of the longitudinal axis. The switches consist of a frame, insulation, current-carrying system, and a grounding circuit. The contact group of the switch is made in the form of a multi-strand braided, tinned wire ("braid"). The contact point is made of a lamella and a jaw. Support insulation is made in accordance with GOST 9920-89 and is designed for pollution degree class IV (creepage distance 420 mm); the insulators are made of polymer material. The frame coating is applied by hot-dip galvanizing.
