A system of material boundaries in the form of a solid dielectric rod or dielectric-filled tubular conductor capable of guiding high-frequency electromagnetic waves.

Test result of dielectric strength, partial discharge and endurance property are analyzed and contrasted between solid dielectric is two film and tree film in model capacitor elements.

In the early 80's, HDW invented, patented and developed the Arc Reflection Technology, which continues to represent the state-of-the-art fault locating method for solid dielectric cables.
