Fire Alarm Signal Cable ZR RVS NHRVS 2×1.0 1.5

Ordinary ordinary signal wires lack fire safety performance and cannot adapt to building fire protection engineering standards. Common non-fire-rated cables are flammable and prone to flame spreading during fire accidents, causing secondary disaster risks and system paralysis. Low-grade cables adopt impure copper conductors with high resistance, resulting in unstable signal transmission, weak current attenuation and delayed alarm response. Untwisted single-core wires suffer from severe electromagnetic interference in dense weak-current wiring environments, leading to signal disorder and system misjudgment. Conventional wires have poor insulation aging resistance, easy cracking and leakage after long-term indoor operation, bringing hidden dangers to fire safety circuits. In high-rise buildings, shopping malls, hospitals and public facilities, unqualified fire alarm cables fail to maintain circuit continuity under high-temperature fire conditions, delaying emergency evacuation and rescue work. The ZR-RVS / NH-RVS Fire Alarm Signal Cable thoroughly solves the above industry pain points. Adopting standard 2-core twisted pair structure, it effectively suppresses external electromagnetic interference and internal signal crosstalk, ensuring precise and stable alarm signal transmission. High-purity oxygen-free copper stranded conductor provides ultra-low resistance and stable current conduction, avoiding signal attenuation and circuit failure. ZR flame-retardant insulation self-extinguishes and prevents flame spread, while NH fire-resistant version adopts professional mica tape fire-resistant layer, maintaining normal circuit operation for a certain period under high-temperature flame baking. Upgraded anti-aging PVC insulating sheath resists long-term indoor temperature changes and aging deformation, adapting to long-term uninterrupted operation of fire safety systems. Strictly produced in accordance with fire protection industry standards, it meets mandatory safety specifications for building fire alarm linkage wiring.

This fire-grade RVS signal cable supports diversified personalized customization for building automatic fire alarm systems, smoke detector linkage circuits, emergency broadcast control, fire fighting linkage equipment and public building fire safety engineering projects. Professional double-twisted pair design greatly enhances anti-interference capability, ensuring accurate signal transmission in complex weak-current integrated wiring environments. Dual safety grades optional: ZR flame retardant grade prevents fire spreading and secondary combustion; NH fire-resistant grade maintains circuit continuity in fire high-temperature environments to guarantee emergency system operation. High-flexibility stranded copper conductor supports repeated bending and concealed pipeline laying, adapting to complex indoor corner wiring. Standard 2×1.0mm² and 2×1.5mm² mainstream specifications fully cover conventional fire alarm and linkage power signal demands. Color-coded insulation design facilitates quick identification, construction wiring and later circuit maintenance. Wear-resistant and anti-aging insulating material ensures long-term stable service life for building fire safety systems. According to project demands, we can customize wire gauge, fire protection grade, insulation color, LSZH low-smoke halogen-free upgrade and packaging specifications to meet refined fire engineering safety standards.
