Pyrotenax MI 2-Core 1.5mm² Fire-Rated Mineral Insulated Cable

The nVent Pyrotenax 105-2C1.5 is a mineral insulated (MI) fire-rated cable comprising two 1.5 mm² copper conductors encased in compacted magnesium oxide (MgO) insulation within a seamless copper tube outer sheath, providing an inherently fire-proof cable that maintains circuit integrity throughout the full duration of a building fire without generating toxic smoke or halogen gases. Mineral insulation is the only cable insulation technology proven to maintain circuit function at temperatures exceeding 1000°C — far beyond the 850°C fire performance required by BS 6387 Category CWZ (the most demanding fire resistance classification) and the 950°C/180-minute fire resistance required by IEC 60331-21. Unlike thermoplastic and thermoset cables that rely on flame-retardant compounds to slow fire progression, the Pyrotenax cable has no organic insulation material to burn: its MgO insulation is a refractory mineral that is chemically inert at all practical fire temperatures, making it the only cable technology that is physically incapable of contributing to fire load or smoke density in a fire scenario.

Saudi Aramco's fire safety infrastructure requirements — codified in GI-0002.100 (General Instruction for Fire Protection) and the SAES-E series of electrical specifications — mandate mineral insulated or equivalent fire-rated cables for all life safety system circuits: fire detection and alarm, fire suppression system control, emergency lighting, fire door release, PA/VA system, and emergency power supply to critical loads in process plants and administrative buildings throughout the Kingdom. The Pyrotenax 105-2C1.5 specifically addresses the two-core 1.5 mm² requirement that covers the majority of ARAMCO fire detection panel field wiring: detector loops, call point circuits, and zone input modules are universally wired in 2C 1.5 mm², and the Pyrotenax MI specification exceeds all performance levels required by ARAMCO GI-0002.100 with a documented margin that satisfies even the most demanding ARAMCO project engineer review.

At SABIC's Jubail complex, Pyrotenax MI cable is the specified cable for fire detection panel wiring in all Areas 1 and 2 classified facilities — those containing explosive or flammable materials — where circuit failure during a fire incident would disable the very systems needed to control the emergency. The Ministry of Interior (Directorate of Civil Defence) requires BS 6387 CWZ certified fire circuit cables for high-rise buildings and places of assembly throughout the Kingdom, a requirement that applies to the growing portfolio of Vision 2030 landmark developments: the Qiddiya sports and entertainment city, the Diriyah cultural heritage complex, KAEC City Centre, and Amaala luxury coastal resort. For these flagship projects, Pyrotenax MI cable is specified not only for compliance but for the confidence it provides to project owners, operators, and civil defence authority approvers that life safety circuits will function under the worst-case fire conditions.

Razz Middle East holds Pyrotenax MI 105-2C1.5 in standard 25 m, 50 m, and 100 m coil lengths for immediate despatch, alongside the full range of Pyrotenax termination kits, pot-seal assemblies, test links, and stainless steel clips. Our life safety engineering team provides fire cable selection guidance aligned with Saudi Civil Defence (NFPA 72 and BS 5839-1 based) requirements, ARAMCO GI-0002.100 submittals, and SABIC fire detection panel wiring specifications, ensuring that Pyrotenax MI systems are correctly designed, terminated, and documented for authority approval in KSA.
