A ground rod coupling is a device used to ensure proper grounding of the electrical infrastructure. It helps protect against electrical faults, lightning strikes and provide a safe path for fault currents to dissipate into the earth. It also helps connect the ground conductor to a ground rod in the grounding system. Ground rod couplings are also engineered to withstand the diverse environmental conditions in Southeast Asia. This helps provide reliable grounding solutions for your power infrastructure. Ground rod coupling is from materials such as coper, brass, steel or bronze. Common types include threaded, clamp-on, compression, exothermic welding and parallel ground rod coupling. They find use in applications such as distribution systems, telecommunication networks and industrial facilities among others.
