FIELD: electricity.
SUBSTANCE: electric splitter-radiator for bottomhole MWD is arranged of two cylindrical tubular electrodes, separated from each other by means of dielectric insert. At the same time one electrode is drilling pipe, onto which the second pipe, being the second electrode, is put coaxially and fixed rigidly via electric insulation bush. Besides electrodes are made of non-magnet material, and length of electric insulation bush is less than length of the first electrode, but is more than length of the second electrode.
EFFECT: improved consumer properties, such as durability, reliability, repairability, without complication of technology and increase of manufacturing costs.
