Polycab Jelly Filled Telephone Cables

As opposed to conventional dry core cables that have annealed bare electrolytic copper conductor. Jelly filled cables provide much needed protection from rodents, water logging and moisture.
Apart from the external pvc coating the jelly filling provides extra cover and eliminates cross-talk interference. Polycab jelly filled telephone wires have been known to deliver superior quality of sound and connectivity while remaining robust and easy to maintain. 
These cables easily withstand the volatile discrepancy of temperatures found between server rooms, air conditioned workplaces and everything in between.
