Key Knowledge of Insulating Electrical Steatite Ceramic Fused Body

The Insulating Electrical Steatite Ceramic Fused Body is a crucial element in ensuring the safe and stable operation of electrical systems. Made from high-purity steatite ceramic, it features corrosion resistance, good thermal stability, and outstanding insulation performance. Through meticulously controlled forming processes, it achieves precise dimensions and tight tolerances, guaranteeing compatibility and reliability in fuse assemblies. Available in various types, including Ceramic Body for Fuse Bolted Series and Ceramic Tube for EV British Standard Fuse, it caters to a wide range of applications such as EV charging systems and industrial installations.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Ceramic Tube for High Voltage Fuse is a magnesium silicate material, belonging to the category of magnesium-aluminum silicate ceramics.

 

 

Insulation Resistance: Under normal operating conditions, the insulation resistance of the metallized ceramic body in new energy high-voltage DC contactors is usually greater than 1000MΩ, and some high-performance Ceramic Body for EV Fuses can even reach more than 10000MΩ. This characteristic ensures effective isolation of circuits in high-voltage environments and prevents leakage.

 

Voltage Resistance Capability: The rated voltage it can withstand is generally between 1000V - 3000V, which can meet the needs of high-voltage DC systems commonly used in new energy vehicles, energy storage, photovoltaics and other fields. In a short period of time, Ceramic Casing for Fuse Link can also withstand overvoltage impacts of a certain multiple, such as an impact test of 1.5 times the rated voltage, ensuring stable operation when the system voltage fluctuates.

 

Mechanical Strength: The flexural strength is generally between 200MPa - 500MPa, and the compressive strength can reach more than 1000MPa. The high mechanical strength makes the ceramic body less likely to crack or be damaged when bearing the mechanical stress from contactor action, as well as external vibration and impact, thus ensuring the reliability and service life of the contactor.

 

Adhesion Strength of Metallization Layer: Measured by methods such as tensile testing, the adhesion strength between the metallization layer and the ceramic substrate is usually required to be greater than 20N/mm². This ensures that the metallization layer will not fall off during long-term use and maintains good electrical connection performance.

 

Coefficient of Thermal Expansion: Ceramic Body for Overload and Short Circuit Protection Fuse matches the connected metal components, generally ranging from (6 - 8)×10⁻⁶/K. This can reduce thermal stress caused by temperature changes and prevent cracking or loosening between the ceramic body and metal components.
