Resistivity is a key parameter. Lower resistivity indicates superior electrical conductivity, facilitating the rapid dissipation of current. The module's resistivity should be clearly specified in the product documentation, allowing for comparisons between different products during selection.
Dimensions and weight also impact installation and usage. Larger modules may offer lower grounding resistance but require more installation space. While lighter modules are easier to transport and install, it is essential to ensure they possess adequate structural strength.
Corrosion resistance should be verified through relevant test reports. Some products provide experimental data regarding resistance to salt spray, acids, or alkalis; such information helps assess their suitability for various environments.
