Abstract
A electrical surge protector includes a metal tube having a pair of non-conductive stoppers mounted within each end to form an enclosed cavity therebetween. A conductor wire extends the length of the tube along the axis of the tube and projects through the stoppers. Electrically conductive filings are disposed loosely within the cavity and are of a sufficient quantity to form an electrical bridge between the tube and conductor upon the occurrence of a voltage difference of a predetermined magnitude between the tube and conductor wire. The tube is serially connected to one conductor of a two conductor cable, and the conductor wire is connected to the second conductor of the two conductor cable, such that electrical signals will pass therethrough along each conductor of the two conductor cable. A shunt wire is electrically connected between the tube and earth ground, to shunt any electrical surges and equalize the voltages between the tube and conductor wire.
