Description / Abstract:
This guide establishes typical dimensions for connections of a
gas insulated substation (GIS) to extruded, self contained
fluid-filled, and high pressure fluid-filled (pipe-type) cables in
single and three phase arrangements for voltages 72.5 kV and
above.
The guide applies to both fluid filled and dry type cable
terminations with insulating barrier separating SF6 gas in GIS
housing from the termination fluid.
It also determines the arrangement for dielectric tests of the
termination with simulated GIS enclosure. Responsibilities in
grounding connections, installation, and field tests are also
defined.
Purpose
Connection of a GIS to cables typically requires the
coordination of design, material, installation, and test procedures
of several parties. This guide provides detailed directions for
such coordination.
The guide establishes limits of supply between cable termination
and switchgear manufacturers and assures interchangeability of the
terminations and GIS enclosures.
