Structure of communication optical cable for coal mines:The optical cable should be composed of two main parts: the core of the layer twisted structure or the core and protective layer of the central tube structure

Mining fiber optic cable refers to flame-retardant communication fiber optic cable for coal mines or flame-retardant communication fiber optic cable for coal mines, abbreviated as mining fiber optic cable, coal mine fiber optic cable or coal fiber optic cable, with the model MGTS33

1. Mining optical cable MGTSV is a special application of fiber optic cable in the field of communication, specifically used in the coal mining industry as a communication optical cable. It is an optical cable used in mining applications 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 properties due to the special requirements of the coal mining industry, mainly for the purpose of adding

Due to the flame retardant and rodent proof properties (special environment of mines), coal mines, gold mines, iron mines and other mines, especially coal mines, are prone to accidents. In order to ensure smooth communication and reduce losses in the event of accidents, the State Administration of Work Safety (National Coal Mine Safety Supervision Bureau) has mandated safety certification for all products used in coal mines, including communication optical cables, namely: mining product safety mark certification

3. Because there are no corresponding standards for other minerals such as gold and iron mines, and the comprehensive performance of coal mine optical cables is the standard for mining, which is also a relatively high requirement in the industry

Due to the implementation of standards, other mines generally design and produce according to the fiber optic cables used in coal mines

4. The communication optical cable certified by safety standards only has one model, namely MGTSV, and the corresponding requirements are as follows. Its practical scope is: vertical shafts and tunnels in mines and tunnels

Divided into: a-center bundle tube type (2-12 cores, due to process issues, this process can only produce up to 12 cores)

B-layer twisted type (2-144 cores, generally less than 12 cores tend to use central bundle tube type)

1. Central bundle tube type: from inside to outside, it consists of optical fiber, optical fiber paste, loose tube, thin steel wire (mostly wrapped in a circle), steel strip, PE inner protective layer, and flame-retardant sheath (blue)

2. 144 core mining optical cable layer twisted type: from inside to outside, the central reinforcement (usually made of phosphated steel wire), optical fiber, optical fiber paste, loose tube, zip tie, cable paste, steel strip, PE inner protective layer, flame retardant sheath (blue) are arranged in sequence
