常见问题

What is the primary function of an insulation sleeve in electrolytic cells?

To electrically isolate the cathode bar from surrounding conductive structures, preventing current leakage and short circuits while providing thermal protection in high-temperature environments.

What materials are commonly used for high-temperature insulation sleeves?

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.

How often should insulation sleeves be inspected in industrial applications?

Visual inspections should occur monthly, with comprehensive dielectric testing every 6-12 months depending on operating conditions, temperature cycles, and production intensity.
