Gas-Insulated Transmission Lines

New technology on proven foundations. Whenever overhead power transmission lines cannot be used, our GILs offer an economic, environment-friendly and maintenance-free alternative.

Gas-insulated transmission lines are suitable for:

Thanks to the encapsulated construction that gives protection against the external environment, GILs are an extremely reliable engineering solution. In addition, the simplicity of their design and the fact that they are maintenance-free ensures a long service life while the automatic connection system ensures that the whole system remains gas-tight.

One of the outstanding features of GILs are their low operating losses: which means that less heat is dissipated to the environment and operating costs are significantly lower.

GILs are also ideal for environments that are sensitive to electro-magnetic fields because their construction results in much less electromagnetic field being produced than all other methods of power transmission.

So why not use GILs in order to enjoy as much flexibility as possible when planning power transmission networks that will not only give you maximum economy and environmental compatibility but also provide reliable and maintenance-free service for many decades.

GILs are made up from only very few modular building-blocks. They are easy to adapt to the local landscape by utilising the elasticity of the tubular conductors so any kind of route can be accommodated. Similarly, routing through densely populated built-up areas or across rivers presents no problems either. The actual installation of GILs makes use of normal pipe-laying techniques so project completion times can be reduced to a minimum.

Thanks to the high transmission capacity of GILs they can be linked directly into overhead power line systems without the need for com-pensation measures of any kind.

The modular construction allows any kind of link-up to be employed - thus a direct GIS connection is just as possible as the use of integrated surge diverters or a connection through an outdoor bushing.

And the transmission losses are much less than with conventional cable or overhead power lines.
