Isolated Bonding Bar

Share this

The insulated equipotential bonding bars are accessories that facilitates the equipotential bonding of up to 12 components (AXL-12) or up to 16 components (AL-16) of the earthing system.

At Proinex we have 2 models of insulated equipotential bonding bars that apply to different quantities of connections:

The difference with the other equipotential bonding bars is that its mounting base keeps it isolated from the structure on which it will be installed.

Sometimes, it is required to have a grounding connection collector element, or a grounding connection distributor, that remains isolated from the structure on which it is mounted.

Constituent Parts of the Isolated BEP Bars

  1. 1
    The insulating base
  2. 2
    The equipotentiation bonding bar

The insulating base serves to keep the electronics or instrumentation ground separate from the ground.

The equipotential bonding bars provide bonding and continuity for up to 12 earthing points in the case of our AXL-12 model or up to 16 in the case of the AL-16 model.

Isolated Equipotential Bonding Bar Installation

To install the BEP bar (both models), it is necessary to drill the mounting holes and to fix it using the most suitable means for the surface to which it is to be fixed (wall, metal structure, reinforced concrete, etc.).
