TELEPHONE & SWITCHBOARD CABLES

SHILPI twisted paired cables are best suited for telephone and switchboard cabling applications. the conductor is made of solid annealed, high conductivity bare copper. The conductor is insulated with special grade high-density polyethylene with different colours. The insulated cores are twisted with uniform lay to form pairs and are bunched together in such a manner so as to minimise cross talk. In 50 and 100 pair cables the units of 10 and 20 pairs respectively are identified with colour binders and stranded to form the laid up cable. The laid up cable is further jacketed with a grey colour fire retardant (FR) PVC specially formulated and manufactured in-house, with high oxygen and temperature index. The cables can be used for switchboard and internal telephone wiring in high-rise buildings, offices, factories, hotels, residential complexes, etc. They generally conform to ITD specifications G/ WIR-06/02. May 94. Stringent quality control at every stage, from raw material through manufacturing, upto the finished product, guarantees high quality.
