Development of flame-retardant reflective sheathed photoelectric composite cable for open-pit coal mines
In response to the problems that the cables used in open-pit coal mines are prone to damage and general mining cables cannot meet the requirements for use in this environment,a optoelectronic composite cable for open-pit coal mines has been developed.The structural design of the optoelectronic composite cable is introduced,and the selection and manufacturing of optoelectronic composite cable materials for open-pit coal mines are elaborated in detail.Performance tests have shown that the manufactured optoelectronic composite cable has characteristics such as high strength,oil resistance,heat resistance,corrosion resistance,wear resistance,and flame retardancy,and has a reflective protective sheath.The practical application in the East Open-pit Coal Mine of China Coal Pingshuo Group Co.,Ltd.shows that the photoelectric composite cable is safe and stable,solving the problem of easy damage of the photoelectric composite cable used in the open-pit coal mine.
