- Telephone Cable with cellular polyethylene insulation, jelly filled with petroleum jelly and a polyethylene coating.
- For use in the Local Distribution network.
- Insulated conductors uniformly twisted together to form a pair.
- The water resistant filling compound is applied to the air spaces within the cable core to provide the water-proofnes
- Wrapping is applied over the cable core.
- A flat aluminium foil coated with copolymer on both sides is applied longitudinally over the core covering as screen.
- Black linear-low density polyethylene compound is extruded over the screen.
