In the standard flame-resistant optical fiber cable for mine use, the fibers are positioned in a loose tube made of high modulus plastic. The tubes are filled with water-resistant filling compound. Two steel wires are used as central strength members. Between loose tube and sheath are filled with water proof non-woven fabrics of high density. At last, the cable is completed with a blue PVC sheath.
Color:
Features:
- Proper design and precise control of fiber excess in the loose tube render good tensile strength and temperature performance.
- The flame-resistant blue PVC sheath provides excellent effect of anti-flaming.
- Two parallel steel wires, steel-PE bonded sheath and PVC outer sheath offers good mechanical performance.
Applications: mainly used for transmission of voice, images and data in mine.
Environment temperature: - 40℃ ~ +60℃
Laying Mode: Aerial
