MGTSV-2B Fiber Optic Cable

1. The mining cable MGTSV is a special application of optical fiber cables in the field of communication, specifically designed for the coal mining industry's communication needs. It is used in mining sites 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 mining industry.

3. Due to the lack of 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 the industry.

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

4. The certified communication optical cable with the AN standard is only of the model MGTSV, and the corresponding requirements are as follows. Its practical application scope includes: mine shafts, tunnels, and galleries.

Mining cable structure

Categorized as:a- Centered stranded cable (2-12 cores, due to production process limitations, this method can only produce up to 12 cores)

B-Stranded (2-144 cores, generally favors central tube construction for less than 12 cores)

1. Central Conductor Tube: From inner to outer, 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. Laid 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 consists of single-mode or multimode fibers inserted into a loose tube made of high-modulus plastic, with a water-blocking compound filling the tube.The core of the cable consists of a phosphated steel wire or a steel wire rope coated with polyethylene. The central core is wrapped with a loose tube (or filling rope and signal wire) to form a compact and circular 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 complete the cable.
