ABSTRACT:
A gas insulated transmission line section wherein an inner conductor at high potential is located within an outer sheath at low potential. An insulating gas is disposed within the outer sheath to electrically insulate the inner conductor from the outer sheath. A support insulator is disposed within the outer sheath, and this support insulator supports the inner conductor in a spaced-apart relationship with the outer sheath. Included is a barrier insulator which also supports the inner conductor within the outer sheath. The barrier insulator substantially fills the cross-sectional area between the inner conductor and the outer sheath so as to prevent substantially all arc products and contamination produced in the unlikely event of a fault from migrating past the barrier insulator. By so preventing the migration of these products, the gas insulated transmission line section is effectively compartmentalized and these products cannot contaminate adjacent transmission line sections.
