Fire Resistant Cables
It is a cable that will continue to operate in the presence of a fire. This is commonly known as a circuit integrity (CI) cable and is 2-hour fire-rated. Mineral Insulated (MI) cable has provided this added protection for decades.
Fire resistant or fire rated cables are designed to maintain circuit integrity and continue to work for a specified period of time under defined conditions. The distinction between the two is crucial when it comes to maintaining critical circuits required for life safety or for a safe and immediate plant shutdown.
