产品详细介绍

Fiber count: 2-408 cores
Product model: MGTSV, MGTS32, MGTXSV
Product description:
Mine optic cable refers to fire-retardant communication optic cable for coal mine, simplified as mine optic cable or coal optic cable. Such cable may be divided into stranded cable and central tube cable.
Execution standards:
YD/T901-2009 stranded outdoor communication optic cable
Q/TPY-04-2011 enterprise code
Laying method: pipe, aerial, direct bury, shaft
Application scope: mainly applicable to remote communication in coal mine, as well as inter-unit voice, image and digital signal transmission
Accurate control on spare length of optic fibers guarantees optic cables of good tensile property and temperature property
Material of loose tube compromises water resistance property and higher strength. Tubes are filled with certain pates to conduct critical protection on optic fibers
PE sheath is of good UV resistance performance
Following measures may be applied to maintain waterproof performance of optic cables:
-Single steel wire strengthen core
-Fill loose tube with special waterproof compound
-Fully fill cable core
-Paint PSP dampproof coat on both surfaces
Blue fire-retardant PVC is adopted as secondary sheath in order to realize good fire-retardant performance of optic fibers as well as to facilitate recognition.
