MGTSV-12B 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's communication needs. It is used 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 optical 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 other minerals like gold and iron ore, since the comprehensive performance of coal mine cables is a standard for mining use and also a high requirement in this industry.

Standard execution, thus other mines generally design and produce according to coal mine optical cables.

4. The communication optical cable with ANS certification has only 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-tube design (2-12 cores, due to process limitations, this design can only produce up to 12 cores)

B- stranded (2-144 cores, typically the center tube construction is preferred when less than 12 cores)

1. Central Conductor Tube: Fiber Optics, Fiber Grease, Loose Tube, 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 consists of a central reinforcing element (usually phosphated steel wire), optical fiber, fiber gel, loose tube, tie wraps, cable grease, steel tape, PE inner sheath.

Flame-retardant Sleeve (Blue)

The structure of the flame-retardant optical cable for mining is to place single-mode or multi-mode optical fibers into a loose tube made of high-modulus plastic, with water-blocking compounds filled inside the tube.The cable core features a central phosphated steel wire or a steel wire rope coated with polyethylene. A loose tube (or filling rope and signal wires) encircles 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 complete the cable.
