常见问题

What temperature range can ceramic insulation cores withstand?

Standard alumina cores operate at 800-1600°C, with specialized formulations reaching up to 1800°C for extreme applications.

How do ceramic cores prevent electrical failures in heating elements?

Their high dielectric strength (>15 kV/mm) prevents current leakage between heating wire and sheath, while thermal stability maintains insulation properties at operating temperatures.

Are ceramic insulation cores interchangeable between heating element brands?

Only when dimensional, thermal, and electrical specifications match exactly - consult manufacturer compatibility charts before substitution.
