The insulations for low pressure oil filled cables and for conventional pipe type cables are lapped from high quality insulating papers. Subsequently the paper insulated cable cores are impregnated in appropriate vessels with low viscous oil or high viscous compound.

For manufacture of XLPE insulated high voltage cables, nkt cables disposes of four extrusion lines. Highest quality standards together with latest process control equipment and combined with decades of experience ensure manufacture of cables meeting the highest requirements and enabling development of most advanced power cable systems.
