MGFJS煤礦用光纜采用緊套層絞結(jié)構(gòu)。使用由緊套光纖和芳綸加強(qiáng)元件組成的單芯光纜作為子單元，纜芯的中心是一根非金屬加強(qiáng)芯FRP（可能會(huì)加PE墊層）。子單元絞合在FRP ，外面縱包涂塑鋼帶，最后擠塑一層阻燃護(hù)套而成。
MGFJS cable core with a tight sleeve layer strａnd structure. The use of single core cable by the tight set of optical fiber and aramid fiber reinforced components as a unit, the cable core is a non-metallic strength member (FRP) (may PE blanket). The units are stranded around the strength member. An steel Polyethylene Laminate（PSP） is longitudinally applied over the cable core. Then, the cable is completed with a flame-retardant sheath.
光纜芯數(shù)范圍：4～24芯
Optical cable core number: 4 ~ 24 core
