3. EN50200-2015 Test Method for Fire Resistance of Unprotected Small Cables for Emergency Circuits
Product Features
Voltage level: 300V/500V
2. Temperature resistance range: - 40-90 ℃
Section area: 0.75-1.5mm2
4. Number of cable cores: 1-19 pairs
5. Fire resistance time: 90 min and 120 min, using a ceramic silicone insulation system, which can withstand 15 minutes of fire water spray, and the circuit still continues to work.
6. Bending radius: fixed laying 5D; Non fixed laying 6D (D refers to the outer diameter of the cable)

matters needing attention:
1. Installation of fire-resistant cables. Fire-resistant cables cannot be directly bent by 90 ° (the refractory layer of the cable will undergo long-term stress cracking).
2. The terminals and connection ends of all fire-resistant cables should be damp proof (the fire-resistant layer has moisture absorption, which will affect the electrical performance of the line).
The cross section of the cable conductor should be 1 to 2 larger design cross sections. It is not recommended to select a smaller cross section, such as 0.5mm ² And below, which may fuse the conductor (for reference only)
4. The outer diameter of the cable should be as much as possible using power control cables with a diameter of less than 20mm. If the cable is larger than 20mm, the combustion time will increase.
