ATA/ATL-SF GIS Termination

ATA/ATL-SF GIS Termination

For self-contained and pipe type cable systems, G&W Electric 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.

ATA terminations feature the security of high strength, external porcelain insulation and the proven reliability of perforated paper roll stress control. High pressure fluid style ATA-SF terminations utilize a gasketed stainless steel or aluminum body supplied with a stainless steel or copper pipe stub for field welding or brazing to a riser pipe.

ATL-A-SF is for self-contained cable systems per IEC 60859 Standards. Terminations and termination enclosures for high voltage gas insulated switchgear (GIS) are required in IEC 60859 standards to meet specified dimension requirements in order to be interchangeable. To accommodate this requirement, G&W Electric has modified its line of time proven ATL style terminations to meet the dimensional requirements specified in IEC 60859 standards.
