NG-A (BTLY)/isolated (flexible) inorganic mineral insulated refractory cable
NG-A(BTLY）
NG-A (BTLY) cable is the preferred product for power transmission and security. It uses multi-strand copper wire twisted as a conductor, with excellent conductivity and excellent bending characteristics. The insulating layer is made of inorganic mineral materials, with excellent fire resistance. It follows the British BS6387 standard. It can be powered on at 950℃ for 180 minutes without breaking down. It will be soaked in water for 60 minutes after 180 minutes. The aluminum soft sheath of the cable has been processed with special processes, has good conductivity and mechanical impact resistance, and can also replace ground wire. The isolation layer is composed of high temperature and fire-resistant mineral materials; the outer sheath is made of low smoke or high plastic materials, and has good corrosion resistance. Its continuous molded metal sleeve design effectively prevents moisture, combustible gases and oil vapor from invading, and is waterproof and explosion-proof. The cable has a rated voltage of 0.6/1kV and is widely used in high-rise buildings, subways, hospitals, airports and other places with strict fire prevention requirements, and provides stable power supply to key systems such as fire-fighting equipment and emergency power supplies.

NG-A (BTLY) Isolated (Flexible) Inorganic Mineral Insulated Refractory Cable: Redefining Fire Safety in Critical Systems
NG-A (BTLY), an"isolated (flexible) inorganic mineral insulated refractory cable,"is a revolutionary solution for environments where fire resistance and continuous operation are non-negotiable. Engineered with inorganic materials, this cable combines flexibility with uncompromising fire protection, making it ideal for emergency systems, industrial fire zones, and high-rise infrastructure.
Core Design and Refractory Excellence
NG-A (BTLY) features a copper conductor encased in inorganic mineral insulation (typically magnesium oxide), providing a non-combustible barrier that withstands temperatures up to 1000°C for over 3 hours. The flexible stainless-steel sheath ensures mechanical protection against abrasion and moisture, while an outer thermoplastic jacket enhances installation flexibility. Unlike traditional mineral cables, its isolated design allows multi-core configurations without signal interference, making it suitable for complex control and power systems.
Applications in High-Risk Environments
- Industrial Fire Zones: Powers emergency shutdown systems, boiler controls, and fire suppression mechanisms in refineries, chemical plants, and steel mills.
- Commercial High-Rises: Installed in skyscrapers, hospitals, and data centers for wiring fire alarms, elevator controls, and emergency lighting—critical systems that must remain operational during fires.
- Transportation Infrastructure: Used in subways, airports, and tunnels, where its low-smoke, halogen-free properties comply with strict safety regulations for enclosed spaces.
- Marine and Offshore Platforms: Resists salt corrosion and extreme heat in engine rooms and offshore installations, ensuring reliable operation in maritime emergencies.
Performance and Compliance
- Fire Resistance: Meets BS 6387 (CWZ certification) and IEC 60331 standards, surviving 950°C flames, water jets, and mechanical impacts while maintaining circuit integrity.
- Electrical Stability: Copper conductors ensure low resistance and high conductivity for power and control signals (up to 1000V).
- Longevity: Inorganic materials resist aging, corrosion, and chemical exposure, offering a lifespan of 50+ years in harsh environments.
Why NG-A (BTLY) Outperforms Traditional Cables
- Flexible Design: Unlike rigid mineral cables, NG-A (BTLY) can be bent around corners or through conduits, reducing installation complexity in tight spaces.
- Multi-Core Versatility: Isolated cores prevent cross-talk, making it suitable for combined power and data transmission in smart building systems.
- Regulatory Compliance: Approved for use in public and commercial buildings, NG-A (BTLY) simplifies compliance with strict fire safety codes worldwide.
Conclusion
NG-A (BTLY) cables are a testament to innovation in fire-resistant wiring, offering the rare combination of flexibility, durability, and uncompromising safety. Whether safeguarding industrial operations, commercial buildings, or transportation networks, they ensure critical systems remain functional when every second counts. For projects where"fireproof reliability"and"installation flexibility"are non-negotiable, NG-A (BTLY) sets the standard—proving that advanced inorganic technology can transform cables into lifelines in the face of fire emergencies.
