FIELD: electricity; construction.
SUBSTANCE: to protect electrodes in casing formed by electrodes and electric insulating elements, phase electrode is installed and butt-end of phase electrode is hermetically embedded into one of and electric insulating elements. Chamber formed by coaxially located outer and inner tubular electrodes (the inner electrode is phase electrode) and two electric isolating elements installed at opposite ends of the chamber is used as casing. Inner cam surfaces of electric isolating elements are positioned at angle not exceeding 90° to inner tubular phase electrode. The other butt-end of inner phase tubular electrode is hermetically embedded into the second electric isolating element.
EFFECT: field of utilisation widening and operation reliability improvement of electrodes.
