Gas-Insulated Transmission Line (GIL) System Design

Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful Sulfr hexafluoride tubular conductor technology, which has been around for several decades. GIL consist of a central aluminum conductor with a typical electrical cross section of up to 5,300 mm2. The conductor rests on cast resin insulators, which center it within the outer enclosure. This enclosure is formed by a sturdy aluminum tube, which provides a solid mechanical and electrotechnical containment for the system. To meet up-to-date environmental and technical aspects, GIL are filled with an insulating gas mixture of mainly nitrogen and a smaller percentage of insulating gas gas. This concept also has logistic advantages.All elements such as tubes, angles and special modules are lightweight and small enough to be transported by comparatively light standard trucks.
