FIELD: oil extractive industry.
SUBSTANCE: method includes using galvanic protector made of material having electrode potential lesser than material of body of electric centrifugal pump. Protector is made in form of long-dimensional cylindrical rod with armor along center by steel wire. Protector is placed in under-pump space in well shaft with isolation of contact with well walls. Contact of protector to body of electric centrifugal pump is performed through steel armoring wire.
EFFECT: higher efficiency of body protection from corrosion.
