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.

Abstract: A substantially cylindrical or tubular insulating sheath provides a waterproof protection for a splice or connection between electrical power distribution conductors. An internal rib and shoulder configuration cooperates with the spliced conductors to seal each end of the sheath. The construction is arranged to increase the sealing forces acting upon the sheath responsive to increased pressure either inside or outside the sheath.
