- Voltage Rating: Low voltage (LV: <1 kV), medium voltage (MV: 1-36 kV), high voltage (HV: >36 kV)
- Insulation Resistance: Typically >109 ohms
- Dielectric Strength: Withstand voltage (e.g., 10 kV/mm for ceramics)

Mechanical Specifications- Tensile Strength: Resistance to stretching forces (e.g., 50-100 MPa for porcelain)
- Compressive Strength: Resistance to crushing forces (e.g., 500-1000 MPa for porcelain)
- Bending Strength: Resistance to bending forces (e.g., 50-100 MPa for porcelain)

Environmental Specifications- Temperature Range: Typically -40C to +80C (varies by material)
- Humidity Resistance: Resistance to moisture and humidity
