Couplers for connecting earth rods to tapes, cables and to each other in deep-driven earthing installations. Available for rod-to-tape, rod-to-cable/wire and rod-to-rod connections in gunmetal, aluminium, stainless steel and galvanized steel. Compatible with all ORBITAL earth rod ranges.
ORBITAL couplers are the connecting hardware that completes a deep-driven earth rod installation. They connect rods end-to-end for deep installations, connect rods to tape conductors, and connect rods to cable/wire conductors at the surface. Selecting the correct coupler type and material is important for long-term joint integrity — a corroded or loose coupler joint can significantly increase earthing resistance over time.
Gunmetal (bronze alloy) couplers are the standard recommendation for copper rod systems — excellent conductivity, corrosion resistance and compatibility with copper. Stainless steel couplers are used with stainless steel rod systems. Aluminium and galvanized steel couplers are available as lightweight or economical options for compatible rod materials.
