GAS INSULATED HIGH VOLTAGE CABLE

摘要

A gas insulated cable is constructed from an inner solid, tubular or multistrand conductor and an outer conductor constructed as tubular, seam-welded corrugated strip. The interior space is sealed off through cable end washers but the interior is accessible through valves. Special blind bore elements permit sealing of the ends of multistrand conductors for passage through the end washers. Three way valves are used to interconnect otherwise separated and hermetically sealed cable sections to be interconnected upon installation. The cable is filled with insulative gas and sealed prior to transport to the installation site.
