Mine supply MGTSV SMIC standpipe cable

Mining Cable Mining Optical Cable SMIC standpipe namely coal mine fire communications cable or coal mine fire communications cable, referred to as mining cable, mining cable or fiber optic cable for coal, the model for MGTSV 1, mine is a fiber optic cable MGTSV A special application of fiber optic cable in the field of communications, namely professional communications cable for coal industry, optical cable in coal, gold, iron ore and other mining occasions. 2, mining cable MGTSV not only inherits all the properties of optical fiber and cable, but also because of the special requirements of the coal industry and the addition of a number of special properties, mainly additional performance flame resistant rodent characteristics (mine special circumstances), because coal mines , gold, iron ore and other mines, especially coal mines for the accident-prone, to ensure that when the accident still ensure smooth communication, reduce losses, the State Administration of Work Safety (State Coal Mine Safety Supervision Bureau) mandatory for all coal mines Security certified products, including communications cable, including namely: mining product safety certification mark 3, because others such as gold, iron ore and so on do not have the standard, because the coal mine cable overall performance is the only criterion of mine, is also the industry requiring high performance standards, so that other mine coal with cable generally in accordance with the design and production 4, safety standard certification of communications cable is only one model that is MGTSV, and the corresponding requirements are, in fact, the official practical range is: mines, tunnels shafts, tunnel technical parameters: Fiber count Cable diameter mm Cable weight Kg / km mm minimum bend radius optical fiber tensile properties of N flattening performance N / 100mm static and dynamic short-term long-term short-term 2 ~ 12 11.4 190 10D 20D 1500 600 1000 Note: D indicates Mine cable diameter.
