ABSTRACT:
A lightning arrester having two terminal fittings (3), at least one resistor core (1) which contacts with the latter and which is of voltage-dependent resistance material, and an insulating housing (5) closely surrounding the resistor core (1). A lightning arrester of the generic type is to be created which can be manufactured with relatively low energy expenditure, without additional assembly effort and by a simple process. This is achieved by the housing (5) consisting of a resin matrix with embedded filler, the filler making up over 80% by weight of the housing, and by the housing (5) surrounding at least one resistor core (1) and the region of the terminal fittings (3) contacting the latter. The housing (5) is produced by the setting of a cast moulding compound.
