Underwater Cable - Loose Tube
- For lakes and rivers
- Water depth down to 200 m
- Compact design, down to 20 mm in diameter
- 12 to 192 fibers, G657.A1
- Steel wire reinforcement
- Water blocking Al-foil
The cable is a single armored, loose tube cable for shallow submarine installations where moderate protection is required.
The cable is suitable for lakes and river crossings in all types of networks such as trunk, metropolitan and fiber access networks.
The cables are based on a dry concentric core, slim loose tube design with up to 8 tubes per cable. The tubes made of a robust PBT compound where each tube has 12 fibers.The fibers are protected by an aluminum foil and a polyethylene jacket. Outside the jacket there is a layer of galvanized steel wires covered with a heavy-duty layer of HDPE polymer.
The steel wire reinforcement provides reliable mechanical protection, enabling installation and operation during rough conditions.
1. Primary coated fiber: Silica, acrylate
2. Loose tube: PBT (PA 144 and 192 fiber)
3. Central strength member: Glass fiber reinforced plastic
4. Wrapping: Water blocking yarns
5. Wrapping: Plastic coated Al-foil
6. Sheath: Polyethylene, halogen-free
7. Armouring: Galvanized steel wires
8. Sheath: Polyethylene
Longitudinal water blocking according to IEC 60794-1-22-F5B.
Mechanical and environmental tests in accordance with IEC 60794-1.
Fiber parameters and tests according to the IEC series 60793-2 and 60793-1.
Example of jacket marking, 1 time/meter:
“HEXATRONIC yymmddhh TOL4043005/96C GRHALTL 96/T12 G.657.A1 xxxxx m”
where yymmddhh = year, month, day and hour of manufacture, xxxxx=running meter marking.
The cable will sink and in most installations there is no need to add extra weight to keep it in place.
Max continuous length: 10 km
