HT Cables
KEI manufactures HT XLPE cables up to 33 kV conforming to National and International Standards. The CCV line is available with a single point triple extrusion and computerised sophisticated control and monitoring systems. The process commences with a compacted circular conductor being fed from the pay off stands into the extruder on elevated platform. The conductor passes through extruder’s crosshead, it is covered first with semi conducting screen layer then the XLPE insulation, followed by the outer semi conducting core screen. This crosshead is specially designed to feed three compounds from three extruders at one point described as Singe point Triple extrusion. Thereafter, the extruded core enters and passes through vulcanising line known as CCV line (Continuous Catenary Vulcanising) and the XLPE insulated core is cured in the process. In CV line inert atmosphere is maintained by the Nitrogen gas which is at high pressure and high temperature. This process is popularly known as Single point Triple extrusion CDCC (Completely Dry Cured and Cooled Curing) Process. These cables are available in variety of designs to suit different installations viz. aerial bunched cables, water tight construction, stainless steel armouring, for offshore and ship installations etc.
