BTTRZ/Flexible Copper Sheathed Inorganic Mineral Insulated Fireproof Cable
BTTRZ
BTTRZ cable, namely flexible copper sheathed inorganic mineral insulated fire-proof cable, is a star product in the field of power transmission and safety protection. Its conductors are made of high-conductivity copper materials to ensure efficient transmission of power. The insulation layer is made of inorganic mineral materials, such as high-temperature mica belts, which have excellent insulation properties, can withstand continuous high temperatures of 250℃, and can continuously supply power for 3 hours in extreme environments of 950℃-1000℃, and can work even close to the copper melting point of 1083℃ in a short period of time. The copper sheath is rolled and not only enhances mechanical strength, but also resists certain external force impact and extrusion, but also provides good shielding performance to effectively prevent electromagnetic interference. In addition, the cable is flexible and has a bending radius of only 6-10D, which is convenient for transportation and laying. It can be scattered on the cable tray to reduce transportation damage. Coated with low halogen flame-retardant polyolefin materials to reduce the release of harmful gases during fires. The cable has a rated voltage of 0.6/1KV and is widely used in high-rise buildings, subways, tunnels, airports and other places with strict fire protection requirements, providing reliable power guarantees for key systems such as fire alarms and emergency lighting.

BTTRZ Flexible Copper Sheathed Inorganic Mineral Insulated Fireproof Cable: Ultimate Protection for High-Risk Electrical Systems
The BTTRZ flexible copper sheathed inorganic mineral insulated fireproof cable is a pinnacle of safety engineering, designed to withstand the most extreme environments. As a"Flexible Copper Sheathed Inorganic Mineral Insulated Fireproof Cable,"it combines a robust copper conductor, inorganic mineral insulation, and a flexible copper sheath to deliver uncompromising fire resistance, mechanical strength, and electrical reliability.
Core Design and Fireproof Innovation
At its core, BTTRZ features a stranded copper conductor, ensuring high conductivity and flexibility for easy installation in complex wiring layouts. The inorganic mineral insulation (typically magnesium oxide, MgO) is non-combustible and chemically inert, maintaining structural and electrical integrity at temperatures up to 1000°C. This insulation eliminates smoke, toxic fumes, and fuel for fires, making it ideal for critical systems in fire-prone zones. The flexible copper sheath adds a layer of protection against moisture, corrosion, and physical impacts while allowing the cable to bend (minimum radius: 6D), a rarity in rigid fireproof cables.
Applications in Demanding Environments
BTTRZ cables are engineered for scenarios where failure could have catastrophic consequences:
- Industrial Fire Zones: Used in refineries, chemical plants, and steel mills to power control systems, emergency shutdown mechanisms, and high-temperature machinery.
- Commercial High-Rises: Installed in skyscrapers, hospitals, and data centers for fire alarm systems, elevator power, and emergency lighting—circuits that must remain operational during fires.
- Infrastructure Projects: Suitable for subway tunnels, airports, and offshore platforms, where the cable’s waterproof copper sheath and fire resistance meet dual safety demands.
- Renewable Energy Sites: Resists harsh outdoor conditions in solar and wind farms while providing fireproof wiring for critical components.
Performance Standards and Compliance
BTTRZ cables adhere to strict international fire safety standards (e.g., IEC 60331, BS 6387), proven through rigorous testing:
- Fire Resistance: Withstands 950°C flames for 3 hours, even under water spray and mechanical 冲击 (impact), ensuring continuous operation during emergencies.
- Low Smoke and Halogen-Free: Emits minimal smoke and zero harmful halogens when exposed to fire, reducing environmental and health risks in enclosed spaces.
- Mechanical Durability: The copper sheath resists abrasion, rodents, and corrosion, extending the cable’s lifespan to 50+ years in harsh environments.
Why BTTRZ is a Game-Changer
- Flexibility Meets Strength: Unlike rigid mineral-insulated cables, BTTRZ bends easily around corners and through conduits, cutting installation time and costs.
- Dual Protection Layer: The copper sheath provides both fireproofing and physical armor, eliminating the need for separate protective conduits.
- Sustainability: Fully recyclable copper components align with eco-friendly practices, reducing long-term environmental impact.
Conclusion
The BTTRZ flexible copper sheathed inorganic mineral insulated fireproof cable is the gold standard for safety-critical applications. Whether safeguarding industrial operations, commercial buildings, or infrastructure networks, it delivers unmatched fire resistance, flexibility, and durability. For projects where every second counts in an emergency, BTTRZ ensures that electrical systems remain reliable when they’re needed most—proving that advanced engineering can translate into life-saving performance.
