WDZB-BYJ 10mm² Low Smoke Zero Halogen (LSZH) Flame Retardant Building Wire – Solid Annealed Copper Conductor, Cross-Linked Polyolefin Insulation
Premium 10mm² LSZH building wire with solid high-conductivity copper conductor, rated 450/750V, 105°C. Meets IEC 60754, IEC 61034 & BS EN 50525 standards. Ideal for fire-sensitive commercial, residential, and public infrastructure projects. Not for direct burial.
WDZB-BYJ 10mm² – High-Performance LSZH Building Wire for Safe, Sustainable Installations
Engineered for safety, reliability, and compliance in modern electrical systems, our WDZB-BYJ 10mm² is a low smoke zero halogen (LSZH) single-core building wire designed for fixed wiring in walls, conduits, and cable trays. It features a solid annealed copper conductor and cross-linked polyolefin (XLPO) insulation—delivering superior thermal stability, flame resistance, and environmental performance.
✅ Key Features & Benefits
- Low Smoke Zero Halogen (LSZH): Emits minimal smoke and no toxic halogen gases during combustion—critical for escape routes in hospitals, schools, airports, and high-rises.
- Flame Retardant Class B: Complies with IEC 60332-3 Category B (equivalent to GB/T 18380.33 Class B) for bundled vertical flame resistance.
- High-Temperature Rating: Continuous operation up to 105°C (vs. 70°C for standard PVC wires), enabling higher current-carrying capacity and longer service life.
- Pure Electrolytic Copper Conductor: 99.9%+ purity, solid round wire per IEC 60228 Class 1, ensuring low resistance and excellent conductivity.
- Cross-Linked Polyolefin (XLPO) Insulation: Superior to PVC—halogen-free, UV-resistant, and mechanically robust after electron-beam irradiation cross-linking.
- RoHS & REACH Compliant: Free from lead, cadmium, phthalates, and other hazardous substances.
⚠️ Important Installation Notes
- Not suitable for direct underground burial. Must be installed in conduit, trunking, or within building structures.
- Designed for fixed wiring only—not for portable equipment or repeated flexing.
- Minimum bending radius: 6× overall diameter.
