層絞式非金屬加強芯鎧裝光纜（GYFTS） Stranded strengthen the core layer of non-metallic sheathed cable (GYFTS)
·產品描述 Description
GYFTS結構是由多根松套管(或部分填充繩）繞中心非金屬加強構件絞合成圓整的纜芯，纜芯外縱包阻水帶和皺紋鋼帶并擠上PE護套形成鋼-塑粘結護套。松套管是由溫度特性好的材料擠成，管中放入具有合適余長的多根單�；蚨嗄９饫w，并充滿防潮光纖用油膏，纜芯所有縫隙均填充有阻水化合物。 GYFTS root structure is more loose tube (or some fillers) stranded around the central synthesis of non-metallic strength member of the cable core round, outside the cable core longitudinally water-blocking tape and corrugated steel, and squeezed into the PE sheath formed of steel - adhesive plastic sheath. Loose tube is extruded from the temperature characteristics of good material, placed in a tube much longer than the appropriate root of single-mode or multimode fiber, and full of moisture ointment optical fiber, cable core gaps are filled with water blocking all compounds.
產品特點 Characteristics
· 具有很好的機械性能和溫度特性 · Good mechanical and temperature performance
· 松套管材料本身具有良好的耐水性能和較高的強度 · High strength looes tube that is hydrolysis resistant
· 管內充以特種油膏，對光纖進行了關鍵性保護 · Special tube filling compound ensure a critical protection of fiber
·皺紋鋼帶鎧裝層增強了光纜的抗側壓、防彈、防潮性能。 · Crush resistance and flexibility
· 采用下列措施來確保光纜的防水性能： · The following measures are taken to ensure the cable watertight:
- 單根非金屬中心加強芯 - Single Fiber Reinforced Plastic as the central strength member
- 松套管內填充特種防水化合物 - Loose tube filling compound
- 完全纜芯填充 - 100% cable core filling
·產品標準 Standards
GYFTS 光纜符合 YD/T 901-2001 和 IEC 60794-1 標準 GYFTS cable complies with Standard YD/T 901-2001as well as IEC 60794-1.
