Soil Series Effective Protect For Low Resistivity Environments
XCTAT zinc anodes are available in both cast and extruded forms. The cast anodes are produced in a variety of weights and are designed for use in low resistivity soil environments. These anodes are manufactured with lead wires and are package in a backfill consisting of 75% gypsum, 20% bentonite, and 5% sodium sulfate. XCTAT zinc extruded anodes are produced in diamond shaped ribbon coils. Their elongated shape allows for lower resistance-to-earth than conventional zinc anodes and permits easy installation on a multitude of structures. Typical Applications Zinc cast anodes are recommended for use in soils with resistivities below 1,000 ohm-cm because these anodes have a driving voltage which is lower than magnesium, they are most effective on well-coated steel structures which require minimal current output. The packaged anodes are commonly used as grounding cells on electrical motors, panels, and conduits, and across insulators on pipelines to limit dangerously high voltages.
