Features: Stable, high conductivity providing long term low groundresistance. High expansion, low shrink characteristics.Non-toxic, non-corrosive.
Packaging: 20kg non-tear, plastic lined bags.
Installation: Apply as a dry mix or pourable slurry.
Dry mix will yield a volume of approximately 0.0176m3 (roughly 57 bags to the cubicmetre).
Slurry will yield a volume of approximately 0.030m3 when mixed with 20 to 25 litresof water (roughly 33 bags to the cubic metre)
Boxes ERB1 and ERB3 feature hinged inspection lids & cable entry holes on the sides. Bothboxes provide ample space for conductors and clamps.
