Type of Copper Cables

 

The cable is foam-skin polyethylene insulated, quad unit type, jelly filled, laminated sheath telephone cable which is designed for use in subscribers distribution.It features excellent blocking performance for water penetrated and can be installed aerially or underground in ducts.

 

 

FOAM/SKIN POLYETHYLENE INSULATED STALPETH SHEATHED CABLES (F/S-STALPETH)

1. Cable core Conductor: Solid annealed copper Insulation: Foam-Skin polyethylene Layering - Color polyester tape binder.
2. Wrapping: Mylar tape, Non-woven tape and Non-woven water blocking tape.
3. Shield: Corrugated aluminum tape.
4. Armour: Steel tape with anti-corrosion compound.
5. Sheath: Polyethylene.

 

Foam/skin polyethylene insulation with better electrical properties.
Air filled with lighter weight.
The cable is flexible and easy to install.
