Earth Electrode and Wall Bushings

Details

With MV clamp made of StSt (V4A) for round conductors 8-10 mm. For water pressure-tight ducting of the earthing conductor / equipotential bonding conductor through walls and brickwork with StSt threaded rod M10

For subsequent installation through borehole (Ø14 mm) or through the formwork spreader.
Test for water pressure-tightness up to 1 bar features an installation depth of 10 m in stagnant water.

The bushing is ready for connection with MV clamp and all earth contacting components are made of StSt (V4A).
Sealing is performed by the pressing of the neopren disks against the brickwork/wall (fixed and loose flange).
Installation can be implemented from inside. The threaded rod can be held by the lock nuts (inside) when tightening the screws.
