GYTA53
室外光纜系列-層絞式雙鎧雙護通信光纜
Outdoor optical cable series
GYTA53光纜的結(jié)構(gòu)是將單�；蚨嗄９饫w套入由高模量的聚酯材料做成的松套管中，套管內(nèi)填充防水化合物。纜芯的中心是一根金屬加強芯，對于某些芯數(shù)的光纜來說，金屬加強芯外還需擠上一層聚乙烯(PE)。松套管(和填充繩)圍繞中心加強芯絞合成緊湊的圓形纜芯，纜芯內(nèi)的縫隙充以阻水填充物。涂塑鋁帶(APL)縱包后擠一層聚乙烯內(nèi)護套，雙面鍍鉻涂塑鋼帶(PSP)縱包后擠制聚乙烯外套成纜。
GYTA53 cable structure is the single mode or multimode fiber into the loose tube made of high modulus polyester material, the casing filled with waterproof compound. The core of the cable core is a metal core, for some of the core number of optical cable, the metal to strengthen the core need to squeeze a layer of polyethylene (PE). Loose tube (and filled rope) around the center to strengthen the core of the core to strengthen the synthesis of compact circular core cable, the core of the gap filled with water to fill the water filled. The coated aluminum with a a (APL) is longitudinally covered squeeze a layer of polyethylene sheath, double chrome coated strip (PSP) is longitudinally covered after extrusion of polyethylene jacket cable.
精確控制的光纖余長保證了光纜具有良好的抗拉性能和溫度特性松套管材料本身具有良好的耐水解性能和較高的強度管內(nèi)充以特種油膏,對光纖提供了關(guān)鍵性保護良好的抗側(cè)壓性和柔軟性采用下列措施來確保光纜的防水性能：
單根鋼絲中心加強芯。
松套管內(nèi)填充特種防水化合物。
完全纜芯填充。
涂塑鋁帶(APL)防潮層。
Precise control of fiber excess length to ensure the cable has good tensile properties and temperature characteristics of loose tube material itself has good resistance to hydrolysis resistance and high strength tube filled with special cream, the fiber provides critical protection good lateral pressure resistance and softness of the measures to ensure the cable waterproof performance:
a single wire center strengthening core.
Special waterproof compound filled with loose tube.
Full cable core filling.
coated aluminium (APL) moistureproof layer.
