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 times in the order of picoseconds. 11
