Profile: Shital Electric Co. is a dealer of Polycab electrical cables & wires, such as instrumentation cables, flexible cables, sheathed cables, armored cables, submersible cables, and house cables. Co-axial cable is used as a transmission line for radio frequency signals, in applications such as connecting radio transmitters and receivers with their antennas, computer network connections, and distributing cable television signals. One advantage of co-ax over other types of transmission lines is that, in an ideal co-axial cable, the electromagnetic field carrying the signal exists only in the space between the inner and outer conductors. This allows co-axial cable runs to be installed next to metal objects such as gutters without the power losses that occur in other transmission lines, and provides protection of the signal from external electromagnetic interference. Control cables can be used on AC voltage up to & including 1100 V, or DC up to & including 1500 V.
