Preventing Insulation Failure at High Temperatures — Silicon Nitride Composite Insulation Rings Enhance System Safety
2024-10-12
In electrical and furnace systems, insulation breakdown and arcing under high temperatures often cause unexpected shutdowns or component damage. Traditional alumina insulators crack easily under rapid temperature changes, reducing safety and lifespan.
The silicon nitride composite insulation ring provides a dependable solution. Designed with Si₃N₄–SiC composite structure, it combines excellent electrical insulation, mechanical strength, and thermal-shock resistance. Even at 800–1000 °C, it maintains stable insulation resistance and structural integrity.
Its low dielectric constant minimizes power loss, while its high toughness prevents micro-cracks and surface breakdown. Customers using Si₃N₄ insulating rings report over 50 % fewer electrical failures and significantly extended maintenance cycles.
These components are widely used in polysilicon reduction furnaces, induction heating systems, and casting molds, ensuring long-term safety and stability in high-temperature electrical environments.
