Utility and Power Cables
Since the late 1960s we have been developing an entire range of XLPE (cross-linked polyethylene) insulated cables for high voltage-transmission.
This kind of cable consists of a stranded copper or aluminum conductor with an extruded insulation system which is further protected by a metallic shield and an outer sheath. In submarine applications, the cable is normally designed with a lead sheath and outer steel-wire armor
XLPE cables are predominantly used in underground networks, but are gradually replacing traditional paper-insulated, fluid-impregnated cables undersea, as well.
They have several distinct advantages:
