Pv Energy Storage Fuse Ceramic Body
Products Description
Photovoltaic, energy storage, and high-voltage direct current (HVDC) systems place higher demands on fuse ceramic bodies-higher dielectric strength, more stable dimensional consistency, excellent thermal shock resistance, and structural reliability that does not degrade under long-term operating conditions.
This pv energy storage fuse ceramic body was developed specifically for these high-load, high-safety-requirement applications, offering the following core benefits:
Providing a high-insulation main structure for the fuse, ensuring stable arc energy carrying during instantaneous fault current interruption;
Maintaining strength without degradation, cracking, or moisture absorption under high temperature and high DC voltage environments;
Providing long-term, safe, and stable protection performance for the system, improving the overall reliability of photovoltaic energy storage systems.
Suitable for various scenarios, including high-voltage direct current (HVDC), photovoltaic module protection, centralized inverters, industrial and commercial energy storage, and battery cluster protection.
This type of ceramic body is not merely a "material," but a core supporting structure for fuse reliability.
Product Features and Technical Characteristics
High Insulation Performance
Utilizing high-purity alumina ceramic, through a uniform grain structure and low dielectric loss control technology, the ceramic body maintains stable dielectric strength under high-voltage DC conditions.
Even in systems subjected to 800V–1500V DC surge voltage environments, the PV Fuse Ceramic Body maintains safe electrical clearance and creepage distance requirements.
01
Thermal Stability
Fuses generate a high-temperature arc upon interruption of fault current; therefore, the Ceramic Body for Battery Storage Fuse must withstand severe transient thermal shock.
This product undergoes high-temperature sintering and secondary stabilization treatment, maintaining structural stability under both short-term and long-term high-temperature shocks, without deformation or cracking.
02
Excellent Mechanical Strength
Optimized ceramic body density and a dense structural design give the product excellent bending strength and crack resistance.
The Ceramic Body for Eaton Bussmann Series Photovoltaic Fuses maintains high stability during installation, transportation, and long-term vibration environments, preventing dielectric failure due to microcracks.
03
High Surface Finish
Precision grinding technology is used in surface processing to improve smoothness, reduce the risk of arc adhesion, and enhance the stability of the arc release path inside the fuse.
04
Excellent Dimensional Consistency
An automated forming + CNC machining system ensures strict control of Ceramic Body for Fast Acting dimensional tolerances, which helps improve the assembly efficiency of fuse components and reduces electrical performance imbalances caused by structural eccentricity.
05
Intelligent Manufacturing Strength: A Precision Journey from Powder to Finished Product
Raw Material Purification
We only purchase alumina micron powder and quartz sand that meet specific standards, and perform secondary purification and particle size screening upon arrival to ensure the purity and consistency of raw materials are controlled from the source.
Isostatic Pressing and Precision Sintering
The Ceramic Body for BUSSMANN Solar Fuse is formed using cold isostatic pressing technology, which, compared to traditional dry pressing, achieves more uniform density and more complex shapes. In a tunnel sintering furnace, precise temperature control in zones completes the densification and phase transformation of the ceramic.
Automated Melt Welding and Assembly
High-precision laser welding equipment is used to precisely weld micron-sized silver alloy melt onto the terminals, ensuring strong welds, no incomplete welds, and a small heat-affected zone. The entire quartz sand filling and terminal encapsulation process is completed by automated equipment in a clean environment.
