Polycab, the market leaders in Power & Control Cables and fastest growing Company in the Cable industry, offer the widest range of cables and wires in the country. Polycab
Coaxial Cables for Cable TV Network are manufactured at its ultra modern plant at
The center conductor is made of solid electrolytic grade 99.97 pure copper to ensure better signal transmission. The conductor is insulated with foam dielectric made of polyethylene injected with nitrogen gas, which is superior and environment friendly
as compared to chemical foam. The double screen of special composite type bonded Aluminium foil and special grade Aluminium alloy braiding of 60% coverage ensure low
loss in signal quality, additional mechanical strength and resistance to oxide formation in tropical whether conditions. The specially in-house formulated PVC compound used in the jacketing is UV and abrasion resistant.
Polycab Coaxial Cables are fully tested for all parameters by computerized analyzer. Coaxial cables with steel wire armoring can also be supplied for underground applications.
Features & Advantages
■ Minimum loss in signal quality: better reception
■ Higher band width: larger network expansion, 100 plus channels
■ Low attenuation value: less electromagnetic Interference
■ Minimum structural return loss
■ Moisture proof: Ideal for tropical conditions
