MGTSV
室外光缆系列-层绞式矿用阻燃通信光缆
Outdoor optical cable series
1.产品描述
标准矿用阻燃综合光缆（MGTSV）的结构是将单模或多模光纤套入由高模量的塑料做成的松套管中，套管内填充阻水化合物。缆芯的中心是一根磷化钢丝，松套管（或填充绳及信号线）围绕中心加强芯绞合成紧凑和圆形的缆芯，缆芯内的缝隙以阻水填充物，聚乙烯内护套后，蓝色阻燃低烟无卤护套成缆。
Standard for mine fire retardant composite fiber optic cable (MGTSV) is the structure of the single mode or multimode fiber set into the made of high modulus plastic pine casing, casing block water filling compound. Center is a phosphating steel wire core, pine casing (or filling line and signal line) around the center to strengthen the core of the twisted into a compact and circular cable core, core within the gap filler, to block water in polyethylene sheath, blue low smoke zero halogen flame retardant sheath into line.
2.产品特点
精确控制光纤的余长保证了光缆具有很好的抗拉性能和温度特性、松套管材料本身具有良好的耐水解性能和较高的强度，管内充以特种油膏，对光纤进行了关键性保护、良好的抗压性及柔软性、采用下列措施来确保光缆的防水性能、单根钢丝中心加强件、松套管内填充特种纤膏、100%缆芯填充、良好的阻水材料防止光缆纵向渗水、使用温度：-40℃至+60℃、弯曲半径：静态 12.5倍光缆外径、动态 25倍光缆外径、适用：斜井、竖井。
Yu long guarantee the precise control of fiber optical cable has good tensile properties and temperature characteristics, pine casing material itself has good resistance to hydrolysis performance and higher strength, tube filled with special ointment, has carried on the key to optical fiber protection, good compressive resistance and softness, adopt the following measures to ensure that the cable waterproof performance, single wire center special fiber reinforcement, loose tube filling paste, 100% core filling, good water resistance materials, use of waterproofing fiber longitudinal temperature: - 40 ℃ to + 60 ℃, bending radius: static, dynamic 25 times 12.5 times the cable diameter fiber diameter, suitable: deviated well, well.
