1The mining optical cable MGTSV is a special application of fiber optic cables in the communication field, specifically designed for the coal mining industry. It is used in mining environments such as coal mines, gold mines, and iron mines.

2The 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, mainly including:

For flame-retardant and rodent-proof characteristics, especially in mine-specific environments such as coal mines, gold mines, and iron mines—where coal mines are particularly prone to accidents—the State Administration of Work Safety (National Coal Mine Safety Administration) mandates that all products used in coal mines, including communication optical cables, must undergo safety certification: the Mine Product Safety Mark Certification.

3Due to the lack of specific standards for other minerals like gold and iron ore, since the comprehensive performance of coal mine optical cables serves as the standard for mining applications and is a high-execution standard required by the industry, other mines generally design and produce their cables according to the specifications of coal mine optical cables.

Divided into: a - Center Conductor Tube Type (2-12 cores, due to the process, this method can only produce up to 12 cores)

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

1Centered tube style: From inside to outside, it consists of optical fibers, fiber grease, loose sleeve, fine steel wire (multiple wires wrapped in a circle), steel strip, PE inner sheath, flame-retardant jacket (blue).

2Stranded: From the inside out, it includes a central reinforcing element (usually phosphated steel wire), fiber optic, fiber optic grease, loose sleeve, tie wraps, cable grease, steel tape, PE inner sheath.
