Coal mine flame-retardant communication optical 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's communication cables. It is used in mining environments such as coal mines, gold mines, iron mines, and other mining sites.

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 lack of standards for other minerals like gold and iron ores, as the coal mine optical cable boasts comprehensive performance meeting the mining standards and is highly demanded in the industry.

Standard of execution, therefore, 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 range includes: mine shafts, tunnels, and galleries.

Mining Cable Structure

Categorized into:a- Central stranded cables (2-12 cores, due to production limitations, this process can only produce up to 12 cores)

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

1. Central tubular design: Fiber optics, fiber paste, loose sleeve, fine steel wire (multiple strands wrapped in a circle), steel strip, PE inner sheath, flame-retardant jacket (blue)

2. Stranded: Centered with reinforcing elements (usually phosphated steel wire), followed by 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 encase single-mode or multi-mode fibers into a loose-tube made of high-modulus plastic, with water-blocking compounds filled inside the tube.The cable core is centered with a phosphated steel wire or a steel wire rope coated with polyethylene. A loose-tube (or filling rope and signal wires) surrounds the central 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 form the cable.
