MGTSV-36B Fiber Optic Cable

1. The mining cable MGTSV is a specialized application of optical fiber cables in the telecommunications field, specifically designed for the coal mining industry. It is used as communication cables in mining scenarios 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 standards for other minerals like gold and iron, since the comprehensive performance of coal mine cables is a standard for mining use and also a high requirement in the industry.

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

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

Mine cable structure

Categorized as:a- Center-tubular design (2-12 cores, due to process limitations, this technique can only produce up to 12 cores)

B- stranded (2-144 cores, typically using a central tube design for less than 12 cores)

1. Central Conductor Tube: From inner to outer, it consists of optical fiber, optical gel, loose sleeve, fine steel wire (multiple wires wrapped in a circle), steel strip, PE inner sheath, flame-retardant jacket (blue)

2. Stranded: From inside to outside, it consists of a central reinforcing element (usually phosphated steel wire), optical fibers, fiber paste, 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 encase single-mode or multi-mode optical fibers into a loose sleeve made of high-modulus plastic, with the sleeve filled with water-blocking compounds.The core of the cable consists of a phosphated steel wire or a steel wire rope coated with polyethylene. A loose-tube (or filling rope and signal wire) surrounds 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. After bonding with steel-polyethylene, a blue flame-retardant PVC sheath is applied to the cable.
