CGIT: Compressed Gas Insulated Transmission (GIL) CGIT bus systems have been in use worldwide since 1972. First developed by High Voltage Power Corporation, in cooperation with MIT. Since it's inception, CGIT Systems, Inc. has been the world leader in supplying proven solutions for long distance power transmission applications. CGIT provides a compact, reliable and economical alternative to conventional cable systems and overhead lines for power transmission. The effective magnetic shielded design minimizes right-of-way requirements and provides safer operating conditions than air insulated equipment, or conventional cable systems. Standard CGIT systems are suitable for transmission voltages up to 1200 kV, with continuous current ratings as high as 8000 amperes. More than 79 miles of CGIT bus systems have been delivered and installed worldwide. Simple interfaces exist for all types of high-voltage equipment, including GIS, transformers, oil cables and XLPE cables. The CGIT bus system is intended for three phase, 50/60 Hz, and is made in fully assembled & factory tested sections up to 60 feet in length. Changes in direction are accomplished with elbows. The CGIT elbow design enables changes in direction of any angle. This provides designers with flexible layout options and a more economical solution by decreasing the total system length. The CGIT system also includes tee sections for branch circuits and connections to other system components such as SF6 surge arresters.
