NH Fuse Ceramic Body
Products Description
Unlike the white alumina ceramics commonly used in the new energy industry, the NH Fuse Ceramic Body widely utilized, specially formulated yellow aluminosilicate/talc porcelain:
High-frequency insulation characteristics: It possesses an extremely low dielectric loss factor, maintaining stable insulation impedance even under high current frequency fluctuations.
Oxidation and corrosion resistance: The yellow glaze (or unglazed surface) undergoes special physical treatment, effectively resisting moisture, industrial acid mist, and chemical corrosion from arc-suppressing sand.
Thermal expansion matching: Specifically designed to match the thermal expansion coefficients of traditional copper or brass end caps, preventing contact loosening due to thermal stress during temperature rise cycles.
Production Process: The Craftsmanship Chain from Clay to Porcelain
Raw Material Selection
Strictly selected high-purity clay, feldspar, and quartz are used to ensure the characteristic color and physical strength of the yellow porcelain body through chemical proportions for the Ceramic Body for DC Fuse Link.
01
Standardized Ball Milling
Continuous ball milling for over 24 hours achieves micron-level particle size distribution.
02
Vacuum Forming
Eliminating air from the interior of the green body improves the material's density and electrical insulation strength.
03
High-Temperature Firing
Firing is carried out in a high-temperature reducing atmosphere above 1300°C.
04
Fine Grinding and Cleaning
Mechanical fine grinding of the end faces removes burrs, ensuring a perfect fit with the metal contact blade assembly.
05
Application Advantages: A Trusted Choice for Mature Power Grids
Industrial Low-Voltage Distribution Cabinets
The Ceramic Body for Fast Fuses is widely used in standard low-voltage distribution cabinets such as GGD, GCS, and MNS. Their standardized dimensions and excellent interchangeability perfectly match fuse bases from major global brands, making them a standard component in factory and building power distribution systems.
Mining and Metallurgical Industries
In the dusty, vibrating, and load-fluctuating environments of the mining and metallurgical industries, this Ceramic Body for Auto Fuses, with its robust structure and thermal shock resistance, exhibits excellent durability, reducing downtime and maintenance due to fuse failures.
Rail Transit and Infrastructure
In infrastructure such as subway traction substations and airport power distribution centers, as the housing of high-reliability fuses, its long-term insulation aging performance has withstood the test of time, ensuring continuous power supply to the infrastructure.
Detailed Showcase
A close examination of each Fusing Electronic Ceramic element reveals meticulous engineering attention to detail: a uniform, matte light yellow surface free from sintering color variations, spots, or cracks; rounded corners and uniform wall thickness with no noticeable gradient deviation; smooth, straight inner walls supporting dense, gap-free sand filling; flat, vertical end faces with high parallelism ensuring zero-gap assembly of the end caps; all edges precisely rounded to prevent stress concentration and assembly scratches; optional uniform local metallization layer to enhance sealing strength; standardized laser marking positions supporting batch traceability and quality management. This meticulous attention to detail collectively ensures the ceramic element's reliable arc-extinguishing performance, structural integrity, and high engineering usability in traditional NH fuse applications.
