Product Introduction
Product Introduction
This BBTRZ Flexible Mineral Insulated (MI) Fire-Resistant Cable is a premium safety-focused power distribution solution engineered for low-voltage (0.6/1kV) three-phase four-wire systems. Designed to meet the most stringent global fire safety standards, it delivers uninterrupted power during extreme fire conditions-making it a non-negotiable choice for critical infrastructure. Unlike traditional rigid mineral-insulated cables, this flexible variant balances exceptional fire resistance with simplified installation, reducing project costs without compromising safety. The 3×16mm² + 1×10mm² core configuration is tailored for standard commercial and industrial electrical loads, ensuring reliable performance in diverse applications.
product key technologies
Product Construction
- Copper Conductor: As the core component of the cable, it is made of high-purity stranded copper. It is responsible for transmitting electrical energy, with the characteristics of stable conductivity, low resistance and excellent long-term current-carrying performance, laying a solid foundation for uninterrupted power supply.
- Mineral Insulation Layer: Wrapped around the copper conductor, it is made of non-combustible inorganic minerals. Its main function is to provide high-quality electrical insulation, resist high temperature and flame, effectively prevent short circuit in fire environment, and ensure the normal operation of the cable.
- Fire-Resistant Isolation Layer: Located between the mineral insulation layer and the outer sheath, it plays a reinforcing and protective role. It can enhance the mechanical strength of the cable, block moisture penetration, and isolate the internal core from external mechanical impact, extrusion and other damages.
- Halogen-Free Low-Smoke (LSHF) Outer Sheath: As the outermost protective layer, it is durable and resistant to abrasion, corrosion and aging. In case of fire, it will not release toxic halogens and only emit a small amount of smoke, which can ensure the visibility of evacuation and protect the safety of personnel.
Core Product Advantages
- ✅ Unrivaled Fire Safety Performance:Maintains continuous power supply for over 3 hours under 950℃ flame exposure (compliant with IEC 60331), ensuring critical systems (fire pumps, emergency lighting, alarms) remain operational during fires.
- ✅ Flexible, Cost-Effective Installation:Unlike rigid MI cables, this design allows easy bending and routing around obstacles, eliminating the need for specialized tools or complex pre-fabrication. Reduces installation time and labor costs by up to 40%.
- ✅ Halogen-Free & Low Smoke (LSHF) Compliance:Zero halogen content and low smoke emission during combustion, eliminating toxic fumes that endanger lives and obscure evacuation routes-fully compliant with global public safety standards.
- ✅ Ultra-Long, Maintenance-Free Lifespan:The inorganic mineral insulation resists aging, oxidation, and moisture, delivering a service life of over 70 years with no routine maintenance required, even in harsh environments.
- ✅ Robust Environmental Durability:Withstands mechanical impact, compression, vibration, and extreme temperatures (-40℃ to +250℃), making it suitable for industrial, outdoor, and high-risk applications.
- ✅ Global Compliance:Meets international standards including IEC 60331, IEC 60754, and relevant fire safety codes, ensuring suitability for projects worldwide.
What Are the Product Application Scenarios?
- 🏢 High-Rise & Commercial Buildings: Critical power supply for elevators, fire pumps, emergency lighting, and fire alarm systems in skyscrapers, malls, and office towers, where fire safety is non-negotiable.
- 🏥 Healthcare Facilities: Uninterrupted power for life-support systems, operating rooms, and medical equipment in hospitals and clinics, ensuring continuous patient care during emergencies.
- 🚇 Transportation Infrastructure: Metro tunnels, airports, railway stations, and highway tunnels, where enclosed, high-traffic spaces demand low-smoke, fire-resistant power solutions.
- 💻 Data Centers & Telecom Hubs: Reliable power distribution for servers, UPS systems, and network equipment, preventing costly downtime caused by power failures or fires.
- 🏭 Industrial & Petrochemical Plants: Suitable for high-risk environments with flammable materials, where fire resistance and mechanical durability are essential for safety and compliance.
- 🏟️ Public Venues: Stadiums, convention centers, schools, and government buildings, where large occupancies require fire-safe, low-toxicity power solutions to protect lives and property.
