Abstract: A GROUND ROD IS MADE FROM A SACRIFICIAL ANODE CORE INSIDE A HARDENED SHEATH OR JACKET. THE SHEATH IS SPLIT LONGITUDINALLY, AND THEN THE LONGITUDINAL CORNERS OR EDGES ARE TURNED IN TO PROVIDE A LOCKING KEY WHICH FITS INTO LONGITUDINAL GROOVES ON THE ANODE CORE, THUS COMPLETING THE GROUND ROD. THIS MAKES A STRONG ROD WHILE EXPOSING THE ANODE CORE. THIS WAY, A STEEL JACKET, FOR EXAMPLE, PROVIDES THE MECHANICAL STRENGTH REQUIRED FOR A DRIVEN GROUND ROD AND A EXPOSED ANODE (FOR EXAMPLE, ZINC) PROVIDES A SACRIFICIAL ANODE. OTHER ANODE MATERIAL SUCH AS MAGNESIUM AND ALUMINUM MAY ALSO BE USED.
