For self-contained and pipe type cable systems per IEEE 1300 Standards G&W GIS terminations are designed in accordance with IEEE 1300 standards for application in gas insulated substations rated 138 through 345kV. Termination designs are available for application on single conductor, low pressure self-contained or high pressure pipe type fluid filled cables.
Low to medium pressure, fluid filled, self-contained paper insulated cable to 100 psi. High pressure, fluid filled, pipe type paper or PPP/PPL insulated cable to 400 psi.
The following steps are needed for ordering: a) Select the terminator by catalog number based on voltage, BIL and conductor size b) Provide a complete description of the cable including the conductor material and diameters over insulation, and shielding system. c) Specify connection lug required based on GIS manufacturer specifications. d) Specify nominal operating pressure of cable. e) Specify nominal operating pressure and interface dimensions with SF6 equipment. f) Specify optional connection lug, if desired. Catalog number includes a flat bus interface connection, corona shield, ground shield, porcelain insulator, aluminum body and flange, semi-stop oil seal, check valves and filters, perforated paper roll stress relief material, riser pipe insulator and base plate insulators. Options include flat or vertical style pad connections, and horizontal pad for tulip connection.
