A new gas discharge tube comprising at least two electrodes and at least one hollow insulator ring fastened to at least one of the electrodes, wherein the insulating ring has an extended length for a creeping current on at least one of the surfaces inside and/or outside compared to its height thereby providing a long distance to any possible creeping current.

Gas discharge tube

A new gas discharge tube with end electrodes having chemically inert surfaces is disclosed. As the surfaces are resistant to the build-up of layers, such as oxide layers, a discharge tube according to the invention exhibits higher selectivity and better performance (e.g. higher heat-resistance and longer life-cycle time) than prior art devices, simultaneously as it offers an environmentally acceptable solution.
