Applications
Finolex switch board cables are best suited for all telephone switch board applications in high rise buildings, offices, factories, hotels, hospitals, residential complexes etc. They generally conform to the ITD specifications S/WS 113C and Finolex specifications and are ideally designed to minimize cross talk.

Features
The conductor is made of electrolytic grade annealed bare solid copper conductor of 0.5 mm diameter and is insulated with a special grade polyethylene compound on the latest state-of-the-art extruders. The cores are twisted together with a uniform lay on a special purpose imported machine, according to the color code to form pairs. The pairs are bunched together in such a manner so as to minimize cross talk. The cable is then jacketed with a specially formulated PVC compound with fire retarding properties. A nylon rip cord provides an effective means of slitting the jacket without damaging the insulation. These are ideal because of low attenuation and low cross talk.
