Co-axial Cable

The Co-axial Cables are designed to transmit radio frequency electrical energy from one point to electronic system equipments. This cable is called Co-axial cable as it consists of an inner conductor, a uniform di electric transmission path ( core di electric) and outer surrounding conductor ( shield) usually braided to allow flexibility. The signals are transmitted through di electric medium and contend between inner and outer conductor.
Generally people are aware that the Co-axial Cable are used in TV sets, Radios, Ethernets and other video equipments.
Constructional specification
RF and Video Co-axial Cables are transmitting video signals with solid Copper centre conductor of different sizes, foamed polythene insulated and further sealed Alluminium foil tapped and Alluminium wire braided with 60% coverage and PVC sheathed Cables
