Description:

• nVent PYROTENAX System 1850Z Jacketed Fire Rated Cable is a range of mineral insulated (MI) 2-hour fire-rated wiring cable for critical and essential circuit protection. It consists of solid copper conductors, in a continuous copper sheath, with a low smoke zero halogen (LSZH) jacket. Developed for transit tunnel applications, it may also be used in other areas where corrosion due to moisture may be of concern. Cable terminations are typically field installed

• When installed in accordance with nVent installation procedures, the result is a UL/ULC 2-hour fire-resistive system. This certification meets the requirements of an “Electrical Circuit Protective System” as referred to in Articles 695 and 700 of the National Electrical Code (NEC). The details of this system appear in Electrical Circuit Integrity System (FHIT and FHIT7), System No. 1850, of the UL and ULC Fire Resistance Directory.

• System 1850 cables are manufactured using only inorganic materials, copper and magnesium oxide. For more details about System 1850, please refer to nVent data sheet H57442. System 1850Z cables are manufactured using our rugged 2-hour fire-rated MI cable and is jacketed with a material that complies with wet-location and "low-smoke, zero-halogen" requirements for transit applications as outlined in NFPA 130. Although developed for transit tunnel applications, it may also be used in other areas where corrosion due to moisture may be of concern, such as rooftops, partially-buried, buried or concrete encased runs or crawlspaces. For more details about approvals and standards, please see the Approvals section
