WDZB1-KYJY23 Control Cable

Advantages
B1 grade high flame retardancy: Passes GB 31247 B1 grade flame retardancy tests (including combustion calorific value, smoke toxicity, smoke production rate, etc.), offering superior flame spread and smoke toxicity control compared to ordinary flame-retardant cables.
Environmentally friendly, low smoke, halogen-free: Emits minimal smoke and releases no corrosive halogen acid gases during combustion, effectively protecting personnel evacuation routes and preventing secondary damage to equipment.
Strong mechanical protection: Double-layer galvanized steel tape armor provides excellent resistance to compression, impact, and biological damage, making it suitable for installation in complex environments such as direct burial and tunnels.
Good temperature resistance: Cross-linked polyethylene insulation supports long-term operation at 90°C, with better heat resistance than ordinary cables.
Wide environmental adaptability: Halogen-free, low-smoke polyolefin sheath is resistant to moisture and UV radiation, and the armored structure is suitable for indoor, tunnel, and harsh outdoor scenarios.
Selling Points
Mandatory high-standard choice for building fire safety: Complies with the mandatory GB 31247 B1 grade cable specifications and features armor protection, making it a required compliance choice for public buildings such as large transportation hubs and hospitals.
Dual safety and protection assurance: Combines B1 grade flame retardancy, low smoke, halogen-free properties, and steel tape armor to meet high standards for both fire safety and mechanical protection.
Reliable design for all scenarios: Suitable for complex environments such as direct burial, tunnels, indoor and outdoor applications, ensuring circuit integrity under fire and external impact.
Green engineering compatibility: Achieves international environmental certifications for halogen-free and low-smoke properties, supporting integration with green building and safety engineering systems.
Application Range: Key projects with the highest requirements for fire safety and mechanical protection, such as subway tunnels, high-speed railway platforms, airport terminals, underground parts of large commercial complexes, and data centers.
Special Notes: Class B1 flame retardant is currently the highest civilian flame retardant level in national standards; halogen-free, low smoke ensures safe evacuation during fires; double-layer armor provides excellent mechanical protection; suitable for harsh environments with pressure and impact risks.
