FIELD: electricity.
SUBSTANCE: arrester for overvoltage protection contains a core consisting of a column of varistor units (1), two connecting units (wherebetween the column of varistor units (1) is fixed), multiple reinforcing elements placed between the connecting units (3) and fixed on them (the reinforcing elements enclosing the column of varistor units) and at least one stabilising disk (25) placed on the section of one of the fines (7); additionally the arrester contains an outer fined body (5) wherein the core is inserted at least partly. According to the invention in the arrester for overvoltage protection the outer body is designed so that the core is inserted without application of an intermediate volume of fluid medium or voids. The stabilising disk contains multiple through holes wherethrough the reinforcing elements are passed.
EFFECT: stability enhancement.
