Have you ran into the issue of chemical compatibility between the cpvc and steel pipe? The way the PVC break detail is presently shown and required to be installed, the incoming ferrous conduit enters the perimeter wall and penetrates the secure area. In most instances, a standard shielded enclosure with 100-dB attenuation may be excessive in protection and cost, while a less expensive alternative shielding approach can provide the required RF protection. I hope you aren't being asked to avoid transmitting sound vibrations through your pipe like one of my clients: That is exactly why we were told that we had to do this arrangement. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric ), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it. As a result, the long-term thermal overload heaters of the overcurrent protective device (circuit breaker) may trip out this device long after an electrical fire has started. With all the above methods of design and construction, acoustical attenuation must be dealt with and designed in.
