Telephone Cables

Telephone cables are suggested for usage in high-rise buildings, offices, industries, hotels, and residential complexes, among other places. Twisted pair cables are most commonly used in telephone cabling applications. The conductor is comprised of electrolytic grade, high conductivity, and solid annealed bare copper. The conductor is insulated using color-coded special-grade high-density polyethylene. The insulated cores are twisted with uniform lay to produce pairs and bunched together in such a way that cross-talk is minimized. The cable is jacketed in grey, specifically formulated fire retardant (FR) PVC with a high oxygen and temperature index.

Tortek created two types of telephone cables: unarmoured cable and armoured cable.
