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 to 550 kV.

This guide establishes typical dimensions for connections of a gas insulated substation (GIS) to extruded, self contained fluid-filled, and high pressure fluid-filled (HPFF) 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.
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.
