A modular, stackable insulating structure for a very high-voltage coaxial cable, comprises at least 3 interspaced insulating tubes accommodating an inner conductor, and an outer conductor of the coaxial cable. A plurality of ribs extending essentially, radially along the longitudinal axis of the structure provide the spacing between, adjacent tubes. The ribs are disposed in an optimized manner such that relatively, effective zig-zag insulating paths are created between the inner and the outer conductors. The structure comprises cooling means. The insulating structure may be used for the transmission of electromagnetic pulses (power peaks) at voltages in the order of megavolts with rise …

Why it's free to use
- Filed May 17, 1993 and granted February 19, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 17, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 17, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
