Empire cable industries, offers pvc and pe cables, value-added product extensions. General construction of xlpe cables: conductors made from electrolytic grade aluminium/copper conforming to is: 8130, and are compact circular or compact shaped; specially made high grade cross-linked polyethlene insulation by extrusion process. Various hardware features of these power and control cables include;power and control cable [aluminium/copper conductor, armoured/unarmoured cables] consist of carbon and hydrogen compounds, which essentially contain low-density polyethylene molecules in the form of long flexible chains. On cross-linking, slippage between flexible chains can be prevented. Crosslinked polyethylene [xlpe] is a thermosetting compound. It softens at the melting point of polyethylene [85ºc to 115ºc] and assumes an elastic rubber like consistency, a property that it retains during further rise of temperature until it become carbonised without melting at 250ºc to 300ºc.
