MGTSV-4B Fiber Optic Cable

1. The mining cable MGTSV is a special application of optical fiber cables in the communication field, specifically designed for the coal mining industry as communication cables for mines, including coal, gold, 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 mining industry.

3. Due to the lack of corresponding standards for other minerals like gold and iron, since the overall performance of coal mine optical cables meets the standards for mining use and is also highly demanded in the industry.

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

4. The certified communication cable with AN standard is a single model, MGTSV, with the following corresponding requirements. Its practical application scope includes: mine shafts, tunnels, and galleries.

Mining Cable Structure

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

B- Braided (2-144 cores, usually center tube style is preferred when less than 12 cores)

1. Centralized bundled cable: Fiber optic cable, fiber paste, loose tube, fine steel wire (multiple strands wrapped in a circle), steel strip, PE inner sheath, flame-retardant jacket (blue)

2. Twisted construction: Center reinforcing element (usually phosphated steel wire), fiber optic, fiber optic grease, loose tube, tie wraps, cable grease, steel tape, PE inner sheath.

Flame Retardant Sheath (Blue)

The structure of the flame-retardant optical cable for mining is to place single-mode or multi-mode fibers into a loose tube made of high-modulus plastic, with the tube internally filled with water-blocking compound.The cable core features a phosphated steel wire or a steel wire rope coated with polyethylene at its center. A loose tube (or filling rope and signal wires) surrounds the central reinforcing core, twisting it into a compact and round cable core. The gaps within the cable core are filled with water-resistant filling material. After bonding with steel-polyethylene, a blue flame-retardant PVC sheath is applied to form the cable.
