Technical Standards
To ensure survivability under rigorous conditions involving direct flame, mechanical impact, and water spray, this product strictly complies with multiple domestic and international authoritative standards:
* Enterprise and Industry Access: Manufactured according to specialized enterprise standard Q/320282 GAD085.
* Fire Resistance Integrity: Meets the testing requirements for maintaining circuit integrity under flame conditions as specified in national standards GB/T 12706.1 and GB/T 19216.21.
* International Recognition: Successfully passed the British standard BS 6387 (*Performance requirements for cables required to maintain circuit integrity under fire conditions*). This certification covers comprehensive assessments for fire resistance (C), fire with water (W), and fire with mechanical shock (Z).
Material Structure and Performance Advantages
The exceptional performance of this cable is derived from its precise structural layers and the application of high-performance materials:
1. High-Conductivity Carrier: The conductor uses high-purity electrical copper, ensuring low-loss power transmission.
2. Core Mineral Insulation: The interior is filled with high-performance composite mineral insulation material, which does not support combustion or melt at high temperatures, maintaining stable electrical performance over extended periods.
3. Flexible Protective Layer: Depending on the specific application and model (such as BTTRZ, BTLY, BBTRZ, etc.), the cable can be equipped with a copper sheath or a low-smoke zero-halogen (LSZH) polyolefin sheath. These provide mechanical protection while ensuring environmental friendliness. The materials offer high light transmittance during combustion, creating favorable conditions for fire evacuation.
4. Anti-aging and Anti-corrosion: The integrated structure possesses excellent resistance to aging and corrosion, significantly extending the service life even in high-load environments.
Technical Characteristics and Installation Specifications
* Thermal Tolerance: The maximum continuous operating temperature of the conductor is rated at 90°C.
* Environmental Adaptability: The cable can withstand installation environments as low as -20°C (with a recommended construction temperature of no less than 0°C) and maintains stable physical properties in extreme climates.
* Installation Flexibility:
* For models equipped with a copper sheath, the allowable bending radius is not less than 20 times the cable's outer diameter.
* For flexible models without a copper sheath, the bending radius can be reduced to 15 times the outer diameter, greatly simplifying wiring in confined spaces and complex corners.
Core Application Scenarios
Due to its superior fire-safety rating and reliability, this product is widely deployed in core buildings and infrastructure requiring strict power continuity:
* Life Support Systems: Ideal for fire linkage control systems, emergency lighting, and automatic sprinkler circuits in high-rise buildings, hospitals, and shopping malls.
* Densely Populated Areas: Critical for subways, airports, tunnels, and large exhibition centers where evacuation is challenging.
* Critical Infrastructure: Suitable for specialized conditions in petrochemical industries, metallurgy, and high-demand environments like data centers and libraries that require strict halogen-free and non-toxic safety standards.
