Two FRP Strengthen Outdoor Fiber Cable Central Loose Tube Type
The fibers are positioned in a loose tube made of a high modulus
plastic. The tubes are filled with a water-resistant filling
compound. The tube is wrapped with a layer of water blocking
system. Two parallel FRP are placed at the two sides. The cable is
completed with a polyethylene (PE) sheath.
The fibers, 250μm, are positioned in a loose tube made of a high
The tubes are filled with a water-resistant filling compound.
The tube is wrapped with a layer of corrugated steel tape
longitudinally. Between the corrugated
steel tape and the loose tube water-blocking material is applied to
keep the cable compact
and watertight. Two parallel steel wires are placed at the two
sides of the steel tape. The cable is completed with PE sheath.
This specification covers the general requirements of Central Loose
Tube Outdoor Cable for aerial or duct.
