Component Specifications

Definition
A ceramic-based insulating core component used in heating elements to electrically isolate the resistive heating wire while providing mechanical stability and thermal management. It maintains structural integrity at elevated temperatures (typically 800-1600°C) and prevents electrical short circuits between heating coils and outer sheaths.
Working Principle
Functions as both electrical insulator and thermal conductor, allowing heat transfer from resistive wire to outer surface while preventing current leakage. The ceramic material's high dielectric strength and thermal stability enable efficient heat generation without electrical hazards.
Materials
Alumina (Al₂O₃) 95-99.5%, magnesium oxide (MgO), steatite, or advanced ceramic composites with purity >95% and density 3.6-3.9 g/cm³.
Technical Parameters
  • Surface Finish Ra <1.6 μm
  • Dielectric Strength >15 kV/mm
  • Compressive Strength >2000 MPa
  • Thermal Conductivity 20-35 W/m·K
  • Dimensional Tolerance ±0.5%
  • Operating Temperature 800-1600°C
Standards
ISO 14720, DIN EN 60672

Frequently Asked Questions

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.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
