F/S-STAL Cable
Application
It is sutiable for trunking or feeding line between central offices and subscribers.
Construction
FOAM/SKIN POLYETHYLENE INSULATED STALPETH SHEATHED CABLES (F/S-STALPETH)
1Cable core Conductor: Solid annealed copper Insulation: Foam-Skin polyethylene Layering - Color polyester tape binder.
2Wrapping: Mylar tape, Non-woven tape and Non-woven water blocking tape.
3Shield: Corrugated aluminum tape.
4Armour: Steel tape with anti-corrosion compound.
5Sheath: Polyethylene.
Property
- Foam/skin polyethylene insulation with better electrical properties.
- Air filled with lighter weight.
- The cable is flexible and easy to install.
