MGTSV-24B Fiber Optic Cable

1. The mining cable MGTSV is a special application of optical fiber 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 specific requirements of the coal mine industry.

3. Due to the absence of standards for other minerals like gold and iron ore, as the comprehensive performance of coal mine optical cables meets the standards for mining use and is also highly demanded in the industry.

Execution Standards, hence other mines typically design and produce using 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 Conductor Cable (2-12 cores, due to the process, this method can only produce up to 12 cores)

B- Braided (2-144 cores, typically uses central tube construction for less than 12 cores)

1. Central Conductor Tube: From inside to outside, it consists of optical fibers, optical grease, loose sleeve, fine steel wire (multiple strands wrapped in a circle), steel strip, PE inner sheath, flame-retardant sleeve (blue).

2. Braided construction: From the inside out, it includes a central reinforcing piece (usually phosphated steel wire), optical fibers, fiber grease, loose tube, ties, cable grease, steel tape, PE inner sheath.

Flame Retardant Sheath (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 a water-blocking compound filled inside the tube.The cable core consists of a phosphated steel wire or a steel wire rope sheathed with polyethylene, with a loose tube (or filling rope and signal wires) surrounding the central reinforcing core to form a compact and round cable core. After filling the gaps within the cable core with water-resistant filling material, the inner protective sheath is bonded with steel-polyethylene, and then a blue flame-retardant PVC jacket is applied to form the cable.
