Mine cable MGTSV knowledge

The optical cables that everyone must know are adss and opgw. They must know less about mining optical cables. After all, it should be used for mining. will go. The following is an introduction to mine fiber optic cable MGTSV.

1. Mining optical cable MGTSV is a kind of optical cable used for communication in the field of communication, but because it is a communication optical cable in the mining industry, that is, in special environments such as coal mines, gold mines, iron mines, etc. It is determined that it is an alternative in communication optical cables.

2. Mining optical cable MGTSV not only has all the performance of optical fiber cable, but also adds many features for the special needs of the mining industry.

Among various mines such as coal mines, gold mines and iron mines, accidents often occur in coal mines, so mine optical cables play an important role in ensuring smooth traffic and reducing losses in accidents. Supervisors of the National Bureau of Coal Mine Safety and Supervision require safety certification for all products such as mining and communication optical cables.

3. Since the country has not issued corresponding standards for gold mines and iron mines, the overall performance of mining optical cables is the standard for mining, and the industry requirements are relatively high.

4. The MGTSV type of communication optical cable certified by safety standards, the practical scope requirements are as follows: mines, tunnel shafts, roads.

The performance and stability of the video surveillance system used in some coal mines in the early years was poor, because the analog surveillance was used in the early stage, and it had great limitations. Analog video signals are prone to loss, distortion and delay, and are susceptible to downhole interference from various devices. The overall performance of the current product has been improved to a higher level, and the above problems can be solved.

The structure of mine optical cable

Divided into: center beam tube type (2-12 cores)

B-layer stranded type (2-144 cores, most of which are less than 12 cores, tend to use the central beam tube type)

1. Center tube type: fiber, optical fiber paste, loose tube, thin steel wire, steel belt, PE inner sheath, flame retardant sheath (blue) from inside to outside.

2. Stranded type: inner and outer (usually phosphoric acid treated steel wire), fiber, optical fiber paste, loose tube, cable tie, cable paste, steel tape, PE inner sheath,

Flame Retardant Sheath (Blue)

The structure of mine flame retardant optical cable is to sheath single mode or multimode optical fiber into high modulus plastic loose tube filled with water blocking compound. The core of the optical cable core is phosphating steel wire or a steel wire rope extruded from polyethylene. The loose tube wraps around the central reinforcing core to form a compact circular cable core. The inside of the cable core is filled with water-blocking filler steel. PVC sheath for fiber optic cable connection.

I hope you can have some understanding of mining optical cables after reading the professionally explained mine optical cables above.
