Coaxial Cables
Relemac Technologies Pvt. Ltd. has the central conductor of solid stranded
bare which electrolytic graded of 99.97% 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 for the aluminium tape with specified coverage. The cable is
then jacketed with a special long lasting UV resistant PVC compound.
Following are the details of Coaxial Cables.
