The following description of another approach to the standard PVC coupling detail might work even better if the incoming ferrous pipe stopped at the exterior perimeter wall and made a transition to the polyvinyl chloride, plastic, heavy wall conduit, which would then penetrate the perimeter wall where it would then re-emerge inside the secure area. This can be done using a dielectric union, flange or coupling, but it must be listed for UFC 4-010-05 (section 3-5.8.2) for military applications. The corner walls are tied together, and RF sealed with a continuous shielding corner seal cap. Dielectric materials can increase the charge storage ability of a capacitor, it can do noise filtering from signals as a part of a resonance circuit, it can also supply power to another component.
