Gas-Insulated Transmission Line (GIL) System Design

Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful insulating gas 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 sf 6 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.

Transmission line - Wikipedia

In electrical engineering, a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. The term applies when the conductors are long enough that the wave nature of the transmission must be taken into account. This applies especially to radio-frequency engineering because the short wavelengths mean that wave phenomena arise over very short distances. However, the theory of transmission lines was historically developed to explain p

Sulfr hexafluoride replacements: switching how we think about power transmission

This problem could be overcome by using gas-insulated lines (GIL). However, the long distances covered by transmission networks (potentially the length of the country) would require large volumes of insulating gas. If that gas was SF 6, the potential climate impact of the enormous amount of banked gas would be unacceptable.
