WDZN─BYJ/hard core low smoke, halogen-free fire-retardant wire

WDZN─BYJ Hard Core Low Smoke Halogen-Free Fire-Retardant Wire: High-Security Solution for Modern Electrical Systems

Dual Breakthrough in Rigid Structure and Fire-Retardant Technology

• Hard Core Copper Conductor: Made of high-purity solid copper (conductivity ≤0.0172 Ω·mm²/m), it offers excellent electrical performance and mechanical strength, suitable for fixed installations in walls and ceilings. Its rigidity ensures superior anti-deformation capability in high-vibration environments like industrial facilities and transportation hubs.
• Low Smoke Halogen-Free (LSHF) Insulation: Constructed with cross-linked polyethylene (XLPE), this insulation releases zero halogens and emits 15% less smoke than traditional PVC insulation during combustion. It fundamentally reduces the risk of toxic gas hazards in fires, complying with the highest safety levels of GB/T 19666.
• WDZN Fire-Retardant Certification: Passing the IEC 60332 vertical flame test, the wire self-extinguishes within 15 seconds after flame removal and does not drip molten beads, effectively suppressing fire spread. This makes it ideal for high-risk areas such as kitchens and data centers.

Safe Applications in Diverse Scenarios

• Residential Fire Safety: Used for home main power lines, smart appliance wiring, and kitchen dedicated circuits. The hard core structure prevents conductor damage from frequent plugging, while LSHF properties gain critical escape time during home fires.
• Commercial Building Core Systems: Applied in emergency lighting, fire alarms, and elevator control systems in offices and hospitals, ensuring critical systems operate continuously during fires and complying with GB 50116 standards.
• Industrial and Infrastructure Projects: Meets the harsh requirements of factory automation equipment and tunnel lighting. The rigid conductor design reduces bending loss during installation, while oil-resistant and moisture-resistant insulation extends the cable’s service life in complex environments.

Performance Parameters and Compliance

• Electrical Performance: Rated voltage 450/750V, long-term working temperature 90°C, short-circuit withstand temperature up to 250°C, compliant with IEC 60227.
• Environmental Certification: RoHS-certified, with insulation recycling rate exceeding 85%, meeting the requirements of LEED green building certification.
• Mechanical Strength: Conductor tensile strength ≥400N, insulation impact resistance 16kJ/m², surpassing the mechanical performance indicators of GB/T 5023.

Three Core Advantages of Choosing WDZN─BYJ

• Upgraded Safety Redundancy: The combination of a hard core structure and fire-retardant insulation provides dual protection, maintaining circuit integrity 30% longer than traditional soft-core cables in fires.
• Optimized Installation Cost: Rigid conductors enable fast pipe threading, reducing labor time by approximately 20% and minimizing rework costs due to cable damage.
• Future Compatibility: Compliant with the EU CPR regulation and China’s GB 51348 standard, it adapts to the long-term demand for LSHF cables in smart buildings.
