To electrically isolate the cathode bar from surrounding conductive structures, preventing current leakage and short circuits while providing thermal protection in high-temperature environments.
High-purity alumina ceramics and silicon carbide composites are standard due to their excellent dielectric properties, thermal stability up to 1600°C, and resistance to chemical corrosion.
Visual inspections should occur monthly, with comprehensive dielectric testing every 6-12 months depending on operating conditions, temperature cycles, and production intensity.
