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 JELLY FILLED LAMINATED SHEATH CABLES (F/S-JF-LAP)

1. Conductors-Soild annealed copper wire Insulation-Foam-skin polyethylene Layering - Color polyester tape binder.
2. Identification tape - Lettering mylar tape Wrapping-Mylar tape
3. Core covering-Water blocking yarn
4. Sheath- Laminated aluminum type and polyethylene

 

The foam/skin polyethylene insulation with better electrical properties.
Have good mechanical and electrical characteristics.
The cable is flexible and easy to install.
