Ceramic Tube For EV British Standard Fuse
Products Description
This product is a Ceramic Tube for EV British Standard Fuse, a core insulation component specifically designed for DC fuses in electric vehicles and photovoltaic energy storage systems that comply with British Standard (BS) and mainstream international specifications. As a critical element for arc isolation and structural support within the fuse, it must withstand system voltages up to DC 1500V and effectively suppress arc propagation and maintain mechanical integrity during short-circuit current surges (≥100kA). The product is made of high-density alumina ceramic with a purity of over 96%, manufactured through precision molding and high-temperature sintering processes, resulting in excellent electrical insulation, thermal stability, and mechanical strength.
Core Advantages and Competitive Advantages
Ultimate Safety and Insulation
- Superior Dielectric Strength: The Ceramic Bodies for Bussmann Series Photovoltaic Fuses boasts a dielectric strength ≥18kV/mm, providing reliable insulation protection under high-voltage environments and preventing electrical breakdown.
- High Volume Resistivity: With a volume resistivity ≥10¹⁴Ω·cm, leakage current is virtually nonexistent even under high voltage.
Extreme Heat Resistance and Arc Resistance
- Temperature Limit: Wide long-term operating temperature range -40°C to +1250°C, maintaining structural integrity under the high-temperature impact of arc discharge without cracking due to thermal expansion.
- High Bending Strength: Bending strength ≥350MPa (some models ≥300 MPa), making Ceramic Body for High Speed Fuses resistant to breakage even under mechanical impact under high voltage.
