Self-Developed B1 Grade Flame-Retardant Fire-Resistant Cables Successfully Pass National Testing

The B1 grade flame-retardant fire-resistant cables independently developed by People's Cable Group have successfully passed full performance testing by the National Quality Inspection and Testing Center for Fireproof Building Materials. The combustion performance achieved the highest B1 grade standard, marking a significant technological breakthrough for the company in the high-end building cable sector.

The product utilizes a novel ceramicized fire-resistant silicone rubber insulation material and a special stranding structure. It maintains circuit integrity for over 180 minutes when exposed to 950°C flame, while also featuring environmentally friendly characteristics such as low smoke, zero halogen, and flame retardancy. It can be widely applied in locations with stringent fire protection requirements, including high-rise buildings, subways, airports, and hospitals.

The series has now entered full production and has secured procurement for multiple key projects.
