Outdoor Underground Directly Buried Stranded Loose Tube Cable GYFTA53
Outdoor Underground Directly Buried Stranded Loose Tube Cable GYFTA53
The loose tube fiber cablee are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A Fiber Reinforced Plastic (FRP) locates in the center of core as a non-metallic strength member. The tubes (and fillers) are stranded around the strength member into a compact and circular core. An Aluminum Polyethylene Laminate (APL) is applied around the cable core. Then the cable core is covered with a thin polyethylene (PE) inner sheath, which is filled with jelly to protect it from water ingress. After a corrugated steel tape armor is applied, the cable is completed with a PE outer sheath.
Features and Benefits:
• Good mechanical and temperature performance
• Stranded loose tube improves the tensile strength
• Metal strength member provides excellent strain performance
• Double-jacket structure enusres moisture resistance and crush resistance
• Steel tape and aluminum tape enhances water-blocking & moisture-proof performancePE or AT sheath ensures safety of cable in high voltage environment
Application:
• Used for duct and buried laying method
• Adopted to outdoor distribution
• Specially used where good mechanical performance and rodent resistance are expected
