Ivep Outdoor Switch-Disconnector

The KBE 3 load-disconnectors and disconnectors can be operated both in horizontal and vertical position. Load-disconnectors have always to be mounted and operated in vertical position. On request the KBE 3 load-disconnectors or disconnectors can be complemented with lightning arresters located in holders and fixed to the devices steel frame. The lightning arrester holders can be mounted in front of the switching device or behind it.
The lightning arrester connecting terminals are interconnected with the main terminals of the disconnector. The line lead-ins or the cable lugs are usually connected to the lightning arresters.
Additionally, the disconnector can be equipped with an earthing clamp of 16 mm diameter and a length of 130 mm, fixed to one end part of the connecting flag.
The KBE 3… outdoor switch disconnectors and disconnectors are controlled from the ground level using the hand operated drive mechanism.
The design of the manual drive is tailored for its attachment to a wooden, concrete or lattice-type steel column. The movement of the drive mechanism is transferred via pipe pull rods onto the operating lever, fixed to the switch disconnector’s shaft. The pull rods are lead through the rocking bearings which are fixed to the pole. The drive and the pull rodsensure the stability of switch disconnector’s end switching positions that cannot move in an unprompted way caused by gravitation, shocks or earthquake.
