BTTVZ Mineral Insulated Fireproof Cable

BTTVZ Mineral Insulated Fireproof Cable

Product Description

The BTTVZ Mineral Insulated Fireproof Cable represents the pinnacle of engineered safety, establishing itself as the definitive solution for electrical circuits where failure during a fire event is inconceivable. This cable employs an elemental, yet profoundly robust, construction: a solid copper conductor is centrally positioned within a seamless copper tube, and the interstitial space is completely filled with highly compressed, pharmaceutical-grade magnesium oxide powder. This creates a hermetic, monolithic structure with no organic components. The inorganic MgO insulation maintains perfect dielectric properties at temperatures exceeding the melting point of copper, ensuring the cable does not merely resist fire but operates continuously within it. The designation "VZ" specifically indicates the addition of an extruded polyvinyl chloride (PVC) over-sheath, which provides critical secondary protection against corrosion, chemical attack, and simplifies installation handling, while the underlying copper sheath remains the primary fireproof and hermetic barrier. This design philosophy results in a cable that is intrinsically non-combustible, non-aging, and capable of maintaining circuit integrity for extended periods under direct flame impingement, water spray, and mechanical shock.

The BTTVZ cable is mandated for the most critical life-safety and operational continuity circuits in modern infrastructure. It is the specified choice for emergency lighting and signage evacuation routes, fire alarm and detection systems, voice evacuation and public address systems, fire pump and smoke extraction fan power supplies, and critical control circuits in nuclear facilities. Its application is ubiquitous in high-risk and high-occupancy environments: skyscrapers, underground rail and road tunnels, airports, hospitals, data centers, and petrochemical plants. The BTTVZ cable's durability also makes it ideal for harsh industrial environments and direct burial applications where long-term reliability is paramount. By ensuring that power and control signals remain available throughout the duration of a fire, the BTTVZ Mineral Insulated Cable provides engineers and specifiers with absolute confidence. It transforms electrical systems from a potential point of failure into a resilient backbone of safety, actively protecting human life, enabling safe evacuation, supporting firefighting efforts, and preserving the functional integrity of essential services during the most catastrophic events.
