We offer highly efficient aluminum conductor, which is manufactured consisting of one or more strands of E.C. grade aluminum. These wires are 99.7% pure and are used in transmission line in rural, distribution urban area where short spans but high conductivity is required. These have excellent corrosion resistance properties and are manufactured as per BS-2l5 (part-I) / ASTM B-230/23l, DIN-48201 and IEC standard. Today, we are well reckoned as one of the distinguished reinforced aluminium conductor manufacturers in India. Insulated aluminum conductor is widely used for overhead secondary distribution lines and is coated with weather proofing polyethylene or XLPE. It is not treated as electrical insulated conductor, but as bare conductor when installed. It mainly provides weather proofing of the conductors and is offered at industry leading prices to clients.
XLPE is the recognized abbreviation for cross-linked polyethylene. This and other cross-linked synthetic materials, of which EPR (ethylene propylene rubber) is a notable example, are being increasingly used as cable insulants for a wide range of voltages.
Polyethylene has good electrical properties and in particular a low dielectric loss factor, which gives it potential for use at much higher voltages than PVC. Polyethylene has been and still is used as a cable insulant, but, as a thermoplastic material, its applications are limited by thermal constraints.
Cross-linking is the effect produced in the vulcanization of rubber and for materials like XLPE the cross-linking process is often described as ‘vulcan- ization’ or ‘curing’. Small amounts of chemical additives to the polymer enable the molecular chains to be cross-linked into a lattice formation by appropriate treatment after extrusion.
The effect of the cross-linking is to inhibit the movement of molecules with respect to each other under the stimulation of heat and this gives the improved stability at elevated temperatures compared with the thermoplastic materials. This permits higher operating temperatures, both for normal loading and under short-circuit conditions, so that an XLPE cable has a higher current rating than its equivalent PVC counterpart.
