CONSTRUCTIONS

CABLE STRUCTURE

Fully waterblocked cable

– Each fibers are inserted into thixotropic gel-filled coloured dual-layer thermoplastic (PC-PBT) loose buffer tubes

– Water ingression protection is applied using swellable compound and tape

Dielectric central strength member

– Glass reinforced plastic (GRP/FRP) non-metallic, anti buckling central strength element

SZ-stranded

– Isolates fibers from installation and environmental rigors

– The loose buffer tube and fillers are SZ-stranded around FRP and bound with polyester yarns

Double Polymer Coated Aluminium Tape

– Aluminium tape as a mositure barrier

Corrugated Steel Tape Armor

– Provides rodent bite protection for direct buried applications

Galvanized Steel Wire Armour

– Provides mechanical protection, the cable can withstand high tensile stress

– Galvanized Steel Wire Armour 2.6 mm diameter X 18 wires

– Other armour size and quantity are available upon on request

Fire Resistant

– Fire resistant tape applied around the middle jacket

– Used in vital communication and emergency systems that remains operated even during a fire

Low Smoke Zero Halogen Flame Retardant (LSZH FR) jacket

– Black UV resistant Low Smoke Zero Halogen Flame Retardant (LSZH FR) sheath

– Reduces the amount of toxic and corrosive fume emission

– Other sheathing are available upon request.
