Stranded Loose Tube Mining Optical Fiber Cable
Description
Mining Cable MGTSV is a special application of optical fiber and cable in the field of communications, which is a kind of optical fiber cable that is used in the coal mine industry and is used in the mine, gold mine and iron mine.
- Mining cable MGTSV not only inherited all the performance of optical fiber and cable, but also because of the special requirements of the coal industry and added many special properties, the main additional sexual
For the fire-retardant characteristics, anti-rat characteristics (special mine environment), due to coal mines, gold mines, iron mines and other mines, especially coal mines for accidents, in order to ensure unforeseen accidents still ensure unimpeded communication, reduce losses, national safety production Supervision and Administration (National Coal Mine Safety Supervision Bureau) mandatory for all products used in coal mines, including communications cable safety certification that is: Mine Safety Certification Mark
- Because other such as gold, iron ore and other corresponding standards, the industry is relatively demanding
Implementation of the standard, so other mines are generally in accordance with the design and production of optical fiber cables for coal mines
- Security standard communication cable only one model that is MGTSV, and the corresponding requirements are as follows, in fact, the official practical range is: mines, tunnel shafts, roadways
Features
-
Good mechanical and temperature performance
-
High strength loose tube has good performance of water proof and high strength
-
Special tube filling compound ensure a critical protection of fiber
-
Crush resistance.
-
Two parallel steel wires ensure tensile strength
-
PSP enhancing moisture-proof and anti rodent
-
Good water resistance material prevent longitudinal seepage
-
Blue flame retardant PVC as second sheath to make the cable has good flame retardant performance.
