Alumina Ceramic For Bolted Connect EV Fuse
Products Description
The Alumina Ceramic for Bolted Connect EV Fuse is the core structural component of high-voltage current-limiting fuses. Unlike ordinary electronic fuses, fuses used in EV and photovoltaic applications need to handle rated currents of hundreds of amperes and breaking capacities of tens of thousands of amperes.
Our white alumina ceramic, through precise control of its microcrystalline lattice, possesses extremely high heat capacity and resistance to arc erosion. When the fuse operates, it not only serves as a carrier for the internal silica sand filling but also plays a crucial role in physical isolation and explosion-proof protection under the high pressure and high temperature environment generated by the electric arc, preventing systemic fires caused by arc flash.
Technical Features: Solving the Physical Challenges of High-Voltage Interruption
Optimized Thermal Shock Resistance
At the moment of arc generation, the local temperature rises sharply. Our Ceramic for Electric and Hybrid Vehicle Fuses undergoes a special heat treatment process, enabling it to withstand instantaneous temperature rises of several thousand degrees without brittle fracture.
Inner Wall Micro-Roughness Control
Precisely controlling the particle state of the Ceramic Tube for High Voltage Fuse inner wall enhances the physical bonding force with the arc-extinguishing medium (such as silica sand), improving overall arc-extinguishing efficiency.
Extremely High Dimensional Tolerance Accuracy
For bolted connection designs, the parallelism and roundness of both ends of the tube are controlled at the micron level, ensuring airtightness after the metal end caps are crimped, preventing arc-extinguishing sand leakage.
Application Advantages: Leading the Future of New Energy and Photovoltaic Energy Storage
New Energy Vehicles (EV/HEV)
Main circuit protection for power battery packs, distribution units (PDUs), and motor controllers (MCUs).
Photovoltaic Energy Storage Systems (ESS)
Overload and short-circuit protection for high-voltage DC systems in combiner boxes and energy storage battery cabinets.
EV Charging
Critical disconnection protection in high-power DC fast charging equipment.
Heavy-duty Rail Transit
Meeting the circuit isolation requirements of high-power locomotives.
Detailed Showcase: The Aesthetics of Craftsmanship from a Microscopic Perspective
| The Matte Texture of Unglazed Porcelain | Unlike some low-end ceramics that are glazed to conceal surface defects, our high-pressure Ceramic Bodies for Energy Storage Fuses are delivered unglazed. This finely ground, matte surface not only eliminates any exposed pores but also provides maximum heat radiation area, aiding in heat dissipation during normal operation. |
| Micro-Chamfering of Edges | Even after the most precise grinding, hard materials retain microscopic sharpness at their edges. We perform micron-level chamfering on all exposed sharp edges of the 95% Alumina Ceramic body. This not only protects the hands of assembly workers from cuts but also prevents micro-chipping during handling due to collisions (chipped areas are often where the electric field is most concentrated). |
| Mirror-like Smoothness of Inner Walls | Through special extrusion and drawing processes, the inner pore walls of the Alumina Ceramic for Bolted Connect EV Fuse exhibit an extremely high level of smoothness. This extremely smooth inner wall significantly reduces the erosion and wear caused by the high-temperature plasma of the electric arc, preventing the ceramic body from being prematurely broken down due to the hollowing out of the inner wall. |
