Product Introduction
Products Description
This Ceramic Body for High Speed Fuse is not a general-purpose insulating shell, but an engineering ceramic component with high-speed arc extinguishing and structural stability as its core objectives. During the melting process, it simultaneously plays the following key roles:
Constructing a stable and controllable internal arc extinguishing space
Maintaining structural integrity under high-temperature transient conditions
Providing high-strength electrical and mechanical isolation to the outside
Establishing a reliable assembly relationship with the metal end cap and the molten metal system
Its design philosophy does not pursue extreme values for a single parameter, but rather balances and optimizes system safety, manufacturing consistency, and long-term service reliability, making it suitable for the long-term operation needs of large-scale new energy equipment.
Material Advantages: Engineering-Grade High-Purity Ceramic System
The Ceramic for Electric and Hybrid Vehicle Fuses body utilizes a high-purity engineering ceramic formulation system, specifically optimized for high-speed fuse operation, offering the following advantages at the material level:
High Thermal Stability: Withstands the high-temperature impact generated during melting, preventing material softening, cracking, or structural collapse.
Excellent Electrical Insulation Performance: Maintains stable dielectric properties under DC high-voltage environments, reducing the risk of surface discharge.
Low Thermal Expansion Characteristics: Effectively alleviates the problem of thermal stress concentration between the ceramic body and metal components.
Dense Structure Microstructure Control: Reduces internal micropores and defects, improving overall mechanical strength and service life.
This material system is particularly suitable for applications in photovoltaic and energy storage systems that frequently experience load fluctuations and environmental temperature variations.
Manufacturing Advantages: Stringent Process Chain
Advanced Molding Technology
We possess multiple large-tonnage isostatic pressing machines and high-precision dry pressing equipment. For large-size Ceramic Tube for High Voltage Fuse bodies, isostatic pressing technology ensures isotropic density of the tube, eliminating structural weak points.
High-Temperature Tunnel Kiln Sintering
We utilize a fully computer-controlled tunnel kiln for isothermal sintering at temperatures above 1600°C. Precise temperature rise curve control ensures uniform growth of 95% Alumina Ceramic grains, preventing micro-cracks.
Precision Post-Processing Capabilities
Equipped with high-precision cylindrical grinding machines and internal grinding equipment, we ensure that the dimensional tolerances of Ceramic Tube for EV DC Fuse tubes are controlled within the micrometer level, fully compatible with fully automated assembly lines.
Application Advantages: Empowering the Photovoltaic and Energy Storage Industries
Enhancing the Breaking Capacity of Photovoltaic Fuses
High-quality ceramic bodies are a prerequisite for fuses to achieve high breaking capacities (such as tens of kA). Using our Ceramic Tube for EV BS Series bodies, customers can easily pass the stringent tests of international standards such as IEC 60269.
Extending Equipment Lifespan
Due to the aging resistance and non-deformation of the Ceramic Tube for EV Charger Fuse Link, fuses manufactured using it maintain their original geometric precision and sealing performance throughout their outdoor lifespan of up to 25 years, reducing maintenance costs caused by casing failure.
Coping with Extreme Climates
Whether in the hot and dry desert photovoltaic power plants or the high-humidity and high-salt coastal wind farms, our Ceramic Body for Fuse Bolted Series bodies remain intact, providing all-weather protection for electrical systems.
