MGTSV-8B 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 fiber optic cables but also adds many special features due to the unique requirements of the coal mining industry.

3. Due to the absence of standards for other minerals like gold and iron ore, as the optical cables for coal mines meet the standards for mining applications and have high industry requirements, they are considered a comprehensive solution.

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

4. The communication fiber optic cable with ANS certification is of a single model, MGTSV, and the corresponding requirements are as follows. Its practical application range includes: mine shafts, tunnels, and galleries.

Mine cable structure

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

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

1. Central Conductor Tube: Fiber Optic, Fiber Paste, Loose Tube, Fine Steel Wire (multiple strands wrapped in a circle), Steel Strip, PE Inner Sheath, Flame Retardant Jacket (blue)

2. Braided: 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 Sheath (Blue)

The structure of the flame-retardant optical cable for mining involves inserting single-mode or multimode optical fibers into a loose-tube made of high-modulus plastic, with water-resistant compounds filling the tube.The cable core consists of a phosphide steel wire or a steel wire rope sheathed with polyethylene, which is surrounded by a loose-tube (or filling rope and signal line) to form a compact and round cable core. After filling the gaps within the cable core with water-resistant filling material and bonding it with a steel-polyethylene adhesive, a blue flame-retardant PVC sheath is applied to the cable.
