Ceramic Body For Automotive Fuses
Products Description
This series of Ceramic Body for Automotive Fuses is positioned for key applications such as automotive high-voltage systems, DC-side energy storage, and photovoltaic inverter protection, and is designed around the following engineering goals:
Providing a stable, dense, and high-temperature-resistant encapsulation space for the fusible element and silica sand
Effectively restraining arc propagation and thermal shock at the moment of melting
Ensuring insulation stability and dimensional consistency during long-term service
Meeting the comprehensive requirements of the new energy industry for safety levels, reliable lifespan, and batch consistency
Its value lies not only in the performance of individual components but also in the improved safety margin of the entire fuse system.
Core Product Properties and Characteristics
| Core Material Characteristics | Utilizing a high-purity alumina EV Fuse Ceramic Body substrate, the white, dense structure is free of pores and impurities, possessing excellent electrical insulation performance and insulation resistance stability. The ceramic material is naturally heat-resistant, maintaining structural stability even at temperatures above 1200℃, readily withstanding the high-temperature arc impact during fuse melting, preventing material softening or cracking. |
| Exclusive White Characteristics | A special formula achieves a pure white appearance for the Ceramic Body for Siemens LV HRC Fuse, with a high surface finish, free of color difference and defects. The white material facilitates defect detection during the production process, accurately identifying minor cracks and impurities; it also meets the clean assembly requirements of new energy vehicles and photovoltaic energy storage equipment, avoiding contamination from impurities that may arise from dark-colored ceramics. |
| Operating Condition Adaptability | Excellent thermal shock resistance, capable of withstanding drastic temperature changes from -50℃ to 800℃ without cracking risk, suitable for the high and low temperature driving conditions of new energy vehicles and the fluctuating day-night temperature range of outdoor photovoltaic energy storage. Strong chemical corrosion resistance, able to withstand the erosion of chemical media such as battery electrolytes and photovoltaic panel cleaning agents, ensuring long-term insulation stability. |
| Structural Adaptability | Supports full-specification customization, allowing for customization of outer diameter, inner diameter, length, wall thickness, and mounting slot dimensions according to the structural requirements of different fuse models (fast-blow, slow-blow, high breaking capacity fuses). High flatness at both ends of the Ceramic Body for EV Fuse, adaptable to the precision packaging requirements of fuse metal end caps, ensuring sealing and mechanical robustness. |
Material and Design Advantages: A "Safety Core" Tailored to Your Application
Material Advantages:
High-Purity Alumina (Al₂O₃): Compared to ordinary ceramics or talc Ceramic for DC Automotive Fuses, high-purity alumina offers higher mechanical strength, superior thermal conductivity (aiding in heat dissipation), and excellent dielectric properties, making it the ideal and only choice for manufacturing high-voltage fuse housings.
Design Advantages:
Collaborative Fuse System Design: We are more than just a ceramic body supplier. Our engineering team can collaborate closely with your fuse design team to collaboratively design the Ceramic for Electric and Hybrid Vehicle Fuses' internal volume, the filler (such as silica sand) filling profile, and the end cap structure, based on your fuse material, rated current, and breaking requirements, achieving optimal performance matching for the entire fuse system.
Detailed Display: Witnessing the Cornerstone of Safety in Every Millimeter
Surface Texture
The surface is a uniform ivory or white, unglazed, crack-free, and spotless, with a delicate matte texture, directly reflecting the purity of the material and the exquisite craftsmanship.
Edges and Holes
All edges are finely chamfered, smooth, and burr-free. The dimensional and positional accuracy of the mounting holes is extremely high, ensuring a perfect seal and assembly with the metal end caps for the Ceramic Tube for EV Charger Fuse Link.
Internal Cavity
The internal cavity surface is smooth, with a regular geometry, free of any adhering substances or impurities, providing ideal space for reliable molten metal movement and rapid arc extinguishing.
Permanent Marking
Permanent specifications, batch numbers, or certification marks can be laser-engraved on the Ceramic Tube for EV British Standard Fuse surface, clear, wear-resistant, and enabling full lifecycle quality traceability.
