Transformer Ceramic Skeleton

The new energy automobile transformer ceramic skeleton is mainly made of ceramic materials, especially alumina (Al2O3) ceramics, with different ceramic grades including 86-94.5 ceramics, 95 ceramics, 97 ceramics, 99 ceramics, and 995 ceramics, which have excellent electrical insulation performance. The transformer ceramic skeleton is mainly applied in fields such as power electronics equipment and new energy generation systems, which are crucial for the high-voltage environment in new energy vehicles, to prevent electrical leakage and ensure the safety and reliability of transformers.

• High Insulation Resistance: Volume resistivity typically exceeds 10¹² Ω·cm, ensuring effective isolation between windings and between windings and the magnetic core. This is vital in high-voltage systems like electric drive systems for new energy vehicles or photovoltaic high-voltage modules.
• High dielectric strength: High breakdown voltage (≥10 kV/mm) enables withstanding high voltages without breakdown.
• Low dielectric constant and loss: For applications requiring high signal transmission speeds or high-frequency operation, ceramics with low dielectric constants and minimal dielectric loss (e.g., talc porcelain, high-alumina porcelain) are essential to minimize distributed capacitance and heat generation. 
• Sufficient mechanical strength: High flexural strength (typically 45-300 MPa) to support coils and resist installation stresses. Capable of withstanding vibration and shock environments common in new energy equipment.
• High thermal conductivity: Rapidly dissipates heat generated during transformer operation, enhancing device stability and lifespan. Efficient heat dissipation is critical for improving power density and reliability in new energy equipment, directly driving the adoption of high-end thermal ceramics (e.g., aluminum nitride) in "ceramic new energy" components.
• High Thermal Stability and Low Coefficient of Thermal Expansion: Resists thermal shock with a thermal expansion coefficient matching that of metal conductors and magnetic materials, preventing cracking or poor contact due to temperature variations.

We adhere strictly to the ISO 9001 quality management system to ensure consistent product quality:

• 100% inspection of raw materials to guarantee quality from the source;
• Utilization of advanced hot-pressing production lines for precise and reliable processes;
• In-house performance testing, including density, hardness, and microstructure analysis;
• Possession of third-party authoritative certifications (such as SGS, CE, ROHS, available upon request).
