MGTS33-8B mining steel wire armored optical cable has complete safety standards

The structure of the flame-retardant optical cable for mining is to encase single-mode or multi-mode optical fibers in a loose tube made of high modulus plastic, and fill the tube with a water-resistant compound. The center of the cable core is a phosphated steel wire or a steel wire rope extruded with polyethylene, with a loose sleeveA compact and circular cable core is formed by twisting (or filling ropes and signal lines) around the central reinforcement core. The gaps inside the cable core are filled with water-resistant filling material, steel polyethylene bonded inner sheath, and then blue flame-retardant PVC sheath is used to form the cable

Mining fiber optic cable structure

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. Layer twisting type: from inside to outside, the central reinforcement (usually made of phosphated steel wire), optical fiber, optical fiber paste, loose tube, cable tie, cable paste, steel strip, and PE inner protective layer are arranged in sequence,
Flame retardant sheath (blue)

Characteristics of Mining Fiber Optic Cables

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

2Mining optical cableMGTSVNot only does it inherit all the performance of fiber optic cables, but it also adds many special properties due to the special requirements of the coal mining industry, mainly for the purpose of enhancing

Due to its flame retardant and rodent resistant properties (especially in special mine environments), as coal mines, gold mines, iron mines, and other mines are prone to accidents, in order to ensure smooth communication and reduce losses in the event of accidents, the Production Supervision and Administration Bureau（*）Mandatory requirement for certification of all products used in coal mines, including communication optical cables, i.e. safety mark certification for mining products-Coal Mine Safety Certification

3Because 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
