Mining explosion-proof optical cable MGTSV mining 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. It is used as communication cables in mining environments 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 lack of corresponding standards for minerals like gold and iron, since the overall performance of coal mine optical cables is a standard for mining applications and the industry has high requirements for it.

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

4. The communication optical cable with ANS certification is only available in one model, MGTSV, and the corresponding requirements are as follows. Its practical application scope includes: mine shafts, tunnels, and galleries.

Mining Cable Structure

Categorized into:a- Center-strand cable (2-12 cores, due to manufacturing limitations, this process can only produce up to 12 cores)

B- Braided (2-144 cores, usually the center tube design is favored when 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. Stranded: Centered with reinforcing elements (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 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 sheathed with polyethylene, surrounded by a loose-tube (or filling rope and signal wires) to reinforce the central core, forming a compact and circular cable core. The gaps within the cable core are filled with water-resistant filling material, followed by a steel-polyethylene bonded inner sheath, and finally, a blue flame-retardant PVC jacket is applied to form the cable.
