Stranded Loose Tube Mining Flame-Retardant Fiber Optic Cable

Product description

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.  are filled with water proof nonwoven fabrics of high density. 

A steel wire, sometimes sheathed with polythene for cable with high fiber count, locates in the center of core as a metallic strengthening member. Tubes are stranded around the strengthening member into a compact and circular cable core. The PSP is longitudinally applied over the cable core which is filled with the filling compound to protect it from water ingress. Then a PE sheath is applied.At last, the cable is completed with a blue PVC sheath.

Scope of use

Mainly used for transmission of voice, images and data in mine.

Applications

Ruggedized cable designs specifically intended for mines, mine shafts and cable                                            
trays used for mining applications. Certified for use by national authorities

Installation method

Aerial or duct

Environment temperature

-40°C~+60°C

Features

1 Proper design and precise control of fiber excess in the loose tube render good tensile strength and temperature performance.

2 The flame-resistant blue PVC sheath provides excellent effect of antiflaming.

3 metallic strengthening member,armored structure,steel-PE bonded sheath and PVC outer sheath offers good mechanical performance.
