Co-axail cables
Copper Conductor Co-Axail 50-75 ohms Armoured / Unarmoured Cables
Today, communication in remote areas is gaining more importance. VSAT networks offer the most cost effective solution for such communication needs. Here, the user's terminal can be connected to a remote office via the VSAT network. Hence day-to-day business communications, such as high quality telephone calls, conferencing, high speed fax transmission, e-mail and more can be done with great convenience. These remote offices can also have high speed data connections that use the satellite to transmit voice and data services. In VSAT networks the cable that connects the Dish to Receiver and the Network Control Centre must be reliable and of high quality. The cables used are of two types 75-ohm impedance and 50-ohm impedance. The cables available in 75-ohm impedance are of RG-6F and RG-11F types and that in 50-ohm impedance are of RG-8F and RG 213F types.
GAS INJECTED PHYSICAL FOAM CO-AXIAL CABLES FOR VSAT NETWORKS
Mahindayal co-axial cables are ideal for use in VSAT and Cable TV networks. They are designed for optimum performance and value for money. In VSAT networks “Mahindayal” coaxial cables provide complete reliability. This means instant, secure communications, without any breakdown. “Mahindayal” co-axial cables have the centre conductor of solid/stranded bare electrolytic grade99.97% pure copper. The secondary conductor is specially designed with poly aluminium tape, applied longitudinally which overlaps and is bonded on the foam dielectric. Aluminium alloy wires with high tensile strength are braided and applied over the aluminium tape with specified coverage. The cable is then jacketed with a special long lasting UV resistant PVC compound.
