MGXTSV-2B Fiber Optic Cable

1. The mining optical cable MGTSV is a special application of fiber optic cables in the communication field, specifically designed for the coal mining industry. It is used as communication cables in mining sites such as coal mines, gold mines, and iron mines.

2. The mining optical cable MGTSV not only inherits all the performance of fiber optic cables but also adds many special features due to the specific requirements of the coal mine industry.

3. Due to the absence of standards for other minerals like gold and iron ore, since the optical cable's comprehensive performance in coal mines meets the standards for mining use and is highly required in the industry.

Execution standards, thus other mines generally design and produce according to coal mine optical cables.

4. The certified communication cables by ANS standard are of only one type, MGTSV, with the corresponding requirements as follows. Its practical application range includes: mine shafts, tunnels, and galleries.

Mining cable structure

Categorized as:a- Center Conductor Cable (2-12 cores, due to production process limitations, this method can only produce up to 12 cores)

B-Stranded (2-144 cores, generally preferring central tube construction for less than 12 cores)

1. Central Conductor Tube: From inside to outside, it consists of optical fibers, fiber grease, loose sleeve, fine steel wire (multiple strands wrapped in a circle), steel strip, PE inner sheath, flame-retardant jacket (blue)

2. Braided construction: From the inside out, it includes a central reinforcing element (usually phosphated steel wire), fiber optic, fiber optic grease, loose sleeve, tie wraps, cable grease, steel strip, PE inner sheath.

Flame-retardant Sheath (Blue)

The structure of the flame-retardant optical cable for mining involves sheathing single-mode or multi-mode fibers into a loose tube made of high-modulus plastic, with a water-blocking compound filling the tube.The cable core is centered with a phosphated steel wire or a steel wire rope sheathed in polyethylene. A loose-tube (or filling rope and signal wires) encircles the center reinforcing core to form a compact and circular cable core. The gaps within the cable core are filled with water-resistant filling material, and then a blue flame-retardant PVC sheath is applied to complete the cable.
