Ceramic Body For Fuse Bolted Series
Products Description
In the rapid development of new energy vehicles and energy storage systems, circuit safety and stability have become core issues. The ceramic body for fuse bolted series, as a key insulating component in fuse protection systems, undertakes multiple functions including heat insulation, electrical insulation, voltage withstand, explosion protection, and mechanical support.
This product uses high-purity alumina Energy Storage Fuse Ceramic Body as the base material, and is formed through high-temperature sintering and precision machining, ensuring structural stability and reliable insulation even under complex environments of high current, high temperature, and high impact. Whether applied to the main circuit protection of new energy vehicles, the safety circuit of energy storage battery modules, or high-voltage DC systems, it provides long life, high strength, and high insulation performance.
Core Value: A Reconstruction of Understanding from Passive Components to Active Safety Systems
Enhanced Electrical Safety Levels
Through a unique microstructure design, the Photovoltaic Energy Storage Fuse Ceramic Body actively participates in arc extinguishing during the breaking process, effectively suppressing plasma gas diffusion and increasing breaking capacity from the traditional 50kA to the 100kA level, meeting the extreme short-circuit capacity requirements of next-generation electric vehicles.
Deeply Enhancing System Reliability
Superior thermal stability ensures structural integrity under extreme temperature differences from -55℃ to 850℃. The coefficient of thermal expansion perfectly matches the metal end cap, avoiding seal failure caused by temperature cycling and significantly extending product service life.
Hidden Value of Lightweight Design and Space Optimization
Compared to traditional ceramic materials, our composite PV Energy Storage Fuse Ceramic Body formula achieves a 20% weight reduction while maintaining the same mechanical strength, providing greater design freedom for compact battery packs and power modules.
Manufacturing Advantages: Comprehensive Control of Precision Ceramics and Precision Welding
High-Precision Ceramic Forming Process
We employ isostatic pressing or dry pressing processes to press high-purity alumina powder into Ceramic Body for High Speed Fuses tube blanks with a high-density, uniform microstructure, which is crucial for ensuring ceramic strength.
Precision Melt Processing and Welding
The melt is formed through precision stamping or chemical etching, achieving dimensional accuracy down to the micrometer level. We use resistance welding or laser welding technology to firmly weld the melt to the metal end cap, ensuring a seamless and resistance-free connection.
Fully Automated Quartz Sand Filling and Encapsulation
In a vacuum environment, quartz sand is uniformly filled into the Ceramic Bodies for Energy Storage Fuse and densified using high-frequency vibration. The end cap is then sealed to the ceramic tube using high-temperature ceramic adhesive or laser welding, ensuring complete isolation between the internal environment and the external environment.
100% Online Performance Testing
Before leaving the factory, every fuse must undergo rigorous resistance testing, withstand voltage testing, and X-ray non-destructive testing to ensure that the internal structure is flawless and the performance parameters are 100% qualified.
