High-Precision Ceramic Components for Power Electronics & High-Voltage Insulation
±0.001mm tolerances | Excellent dielectric strength | Engineered for high-voltage, high-frequency reliability
In the rapidly evolving world of power electronics and energy infrastructure, ceramic components play an essential role in electrical insulation, thermal management, and dimensional stability under extreme voltage and current loads. From electric vehicles to power grids, from inverters to HVDC systems, technical ceramics ensure safety, efficiency, and long-term reliability.
With 20+ years of experience in custom ceramic machining, we manufacture components with micron-level tolerances and proven dielectric performance for the most demanding power applications.
Ceramic Advantages for Electrical & High-Voltage Systems
We machine a wide range of high-performance ceramics such as:
- Alumina (Al₂O₃) – up to 99.8% purity, excellent dielectric strength
- Steatite & Cordierite – used in traditional power devices and insulating bushings
- Aluminum Nitride (AlN) – high thermal conductivity with electrical insulation
- Macor® & Zirconia – for special electrical/thermal hybrid assemblies
These ceramics provide:
- Dielectric strength >15kV/mm
- Low dielectric loss at high frequency
- Stable performance from -50°C to +1000°C
- Non-magnetic, low-outgassing, and arc-resistant surfaces
- High surface resistance and volume resistivity
