Overhead laying&Pipeline laying,Direct burial
GYXTW53 cable is a central loose tube fiber cable with double steel tape and double PE jacket. This cable structure is anti-rodent and suitable to laying in the dust and direct buried under ground. The maximum fiber cable cores is 24cores.
• Good mechanical properties and temperature characteristics
• Two single steel wire as central strength member
• Double side plastic coated steel tape (PSP) moisture-proof layer
• Fiber filling compound protection
• Uni tube for 1-12 fiber counts
• Water-blocking materials
• Double PE sheath
