In an era where fire safety regulations for commercial complexes, high-rise buildings, and critical infrastructure grow increasingly stringent, JINHONG WIRE AND CABLE GROUP proudly presents our B1 Grade High Flame Retardant Wires and Cables—a revolutionary solution engineered to exceed national standards and protect what matters most.

Core Advantages: Unmatched Fire Safety Performance
JINHONG B1 cables go far beyond the self-extinguishing properties of standard flame-retardant cables. Our independently developed halogen-free, low-smoke polyolefin material system, paired with a unique structural design, delivers industry-leading fire performance:
- Minimal flame spread and extremely low heat release during combustion
- Core smoke density indicators that outperform national standards by over 20%
- True "fire extinguishing immediately upon removal from fire" behavior, effectively curbing fire spread
This robust design creates a critical safety buffer for emergency evacuations and firefighting operations.
Dense smoke and toxic gases are the deadliest threats in building fires. JINHONG B1 cables address this head-on:
- Halogen-free formula that produces almost no toxic or corrosive gases when burning
- Specially formulated low-smoke materials ensuring high light transmittance
- Clear visual paths for personnel evacuation and precision equipment protection
This technology maximizes survival chances and minimizes damage to critical systems during a fire emergency.
Durability and traceability are at the heart of our B1-grade cables:
- Crafted from high-purity electrolytic copper and premium polymer materials
- Optimized armor structure for exceptional corrosion, pressure, and impact resistance
- Unique identification code on every reel, enabling full-chain traceability from raw materials to finished products
Every JINHONG B1 cable is built to perform reliably for decades, delivering consistent quality and peace of mind.
Backed by authoritative B1 certification from the National Fireproof Building Materials Quality Supervision and Inspection Center, as well as ISO9001 and CRCC industry system guarantees, our B1 cables meet the highest safety benchmarks.
Aligned with the Chinese national standard GB31247-2014 "Classification of Flame Retardant Performance of Cables and Optical Fibers", JINHONG B1 cables are classified as "flame-retardant Class 1"—one of the highest flame-retardant cable grades available in China’s construction industry.
