Fire Resistant Galvanized Steel Wire Armor (GSWA)
Spesifikasi Teknis
GENERAL

The cable is applicable for above ground, on cable tray/ rack, inside building, at swampy area, in the river or underground.

REFERENCE STANDARDS

The offered fiber optic cable complies to the the ITU-T G.652.D, ITU-T G.654.B, ITU-T G.654.C, ITU-T G.655.C, ITU-T G.655.D, ITU-T G.657.A1, IEC 60794-3, TIA/ EIA standards. Fiber type is optional, following to the customer request.

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

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 as outer protection

– The thermoplastic sheath does not promote the growth of fungus and be free of pits, splits and blisters

– Reduces the amount of toxic and corrosive fume emission

– Other sheathing are available upon request
