8DJH switchgear Busbar extension possible on all individual panels and panel blocks (ordering option)
- Plug-in unit consisting of contact coupling and screened silicone coupling
- Insensitive to pollution and condensation
- Switchgear installation, extension, or panel replacement without gas work
- Busbar connections to metering panels are possible.Every panel block and every individual panel is optionally available with busbar extension on the right, on the left, or on both sides. This offers a high flexibility for the creation of switchgear configurations whose functional units can be lined up in any order. Local installation and lining up is done without gas work.
Lining up takes place as follows:
- By the 8DJH busbar couplings on the medium-voltage side.Tolerances between adjacent panels are compensated byspherical fixed contacts and the movable contact coupling with degrees of freedom in all axis directions.
- By safe dielectric sealing with screened silicone couplings that are externally earthed and adjustable to tolerances.These silicone couplings are pressed on with a defined pressure when the panels are interconnected.
- On free busbar ends, screened dummy plugs are inserted,each of which is pressed on through a metal cover.A common protective cover with a warning is fixed over all three covers.
- By centering bolts for easier switchgear installation and fixing of adjacent panels.
- By bolted panel joints with defined stops for the distances between adjacent panels and the associated pressure for contact pieces and silicone couplings.
8DJH Switchgear installation, extension, or the replacement of one or more functional units requires a lateral wall distance≥ 200 mm.
