Alumina Al2O3 Ceramic EV Relay Case

High-voltage DC relays are the core components of new energy vehicles and charging piles. High-voltage DC relays are packaged with ceramics to obtain a vacuum environment and are safer.

Ceramics have high hardness and high melting point. They will not deform under high temperature and impact, and will not melt under the action of electric arc. They are ideal insulating materials for making high-voltage and high-current electronic components.

The key parameters capability

Leak rate ≤1×10-11 Pa•m3 / s Metal layer tensile strength ≥ 150Mpa
Volume Resistivity ≥108Ω•cm CTE (6.5 ~ 8.0) × 10-6 /°C
Insulation strength ≥18kV/mm (D•C) Dielectric constant 9~10(1MHz, 20°C)
Cosmetic quality: 1. No cracks, no bubbles; 2. Evenly distributed glaze; 3. No contamination
