Volsun FST8017 Series Fireproof Blanket: The Guardian of Cable Safety

Cable fires have always been a major safety hazard for power systems. Traditional fireproofing materials often struggle to balance flexibility for everyday use with fire protection capabilities. Volsun FST8017 composite firestop blanket, with its unique properties of "normally gentle and high-temperature shell formation," creates a dynamic protective barrier for cables and accessories, making it an ideal choice for cable fire protection.

Flexible as cloth, strong as steel

The FST8017 fireproof blanket barrier is flexible and easy to use under normal operating conditions, with an operating temperature range of -60°C to +100°C. It tightly wraps around cables and connectors, requiring no special tools for installation, making it easily adaptable to complex wiring environments such as substations and tunnels. However, once exposed to temperatures exceeding 350°C, it rapidly forms a hard, protective layer, offering fire resistance, fire protection, and thermal insulation. Experiments have shown that even after a fire exposure of 750°C for one hour, the cable surface temperature remained below 130°C, effectively delaying line fusing and ensuring continuous power supply to critical equipment.

Fireproofing and Heat Dissipation: A Perfect Match

Traditional fireproof materials often cause cables to smolder due to over-tight wrapping. Volsun FST8017 fireproof blanket cleverly solves this problem. It does not affect the cable's normal heat dissipation. In the event of a fire, the internal polymer material actively absorbs heat, preventing the spread of flames and buying valuable time for rescue efforts. Furthermore, it complies with RoHS environmental standards, achieving the highest safety level of ZA1 smoke toxicity during combustion, and releases no toxic gases, making it particularly suitable for crowded places like hospitals and subways.

Proven Performance, Verifiable Safety

FST8017 fireproof blanket barrier protective performance has withstood rigorous testing: Even under a 750°C double-torch fire for 90 minutes, the insulation layer of an 8.7kV cable remained intact. After the test, a voltage of 30.5kV was applied for 15 minutes, maintaining structural integrity. Its mechanical properties, including a tensile strength of ≥3.5MPa and a tear strength of ≥20kN/m, ensure it will resist damage during installation and long-term use. These data underscore its widespread application in power substations, subway tunnels, high-rise buildings, and other locations.

Flexible Customization and Free Samples Available

Volsun FST8017 fireproof blanket, with a standard thickness of 15-20mm and dimensions of 800×1000mm, is customizable on demand, ensuring a compatible solution for everything from power cables in industrial plants to power distribution lines in high-rise buildings. 

Choosing Volsun FST8017 firestop barrier blanket elevates cable fire prevention from passive response to active protection, strengthening the safety of power systems.
