    Precision-Engineered Alumina Ceramic Bars For High-Speed Trains Metro Power Systems And Industrial Control Equipment

    Precision-Engineered Alumina Ceramic Bars For High-Speed Trains Metro Power Systems And Industrial Control Equipment


    Product Introduction

    Our alumina ceramic insulation support bars are precision-engineered from 99% high-purity alumina material, specifically designed for insulation support requirements in high-voltage electrical equipment. Featuring hardness above HV1500 and insulation strength >15kV/mm, with specially polished surfaces that withstand over 100,000 mechanical friction cycles, these bars are the ideal replacement for traditional epoxy resin insulation components.

    Primary Applications

    • Power Equipment: High-voltage switchgear insulation supports, circuit breaker isolation bars

    • New Energy: PV inverter insulation brackets, wind power converter isolation parts

    • Rail Transit: High-speed train pantograph insulation supports, metro power supply systems

    • Industrial Control: Frequency converter insulation plates, large motor insulation frames

    • Laboratory Equipment: High-voltage test equipment insulation brackets

    Key Advantages

    Superior Insulation: Volume resistivity >10¹⁵Ω·cm
    Arc Resistance: Withstands arcing for over 180 seconds
    Mechanical Strength: Flexural strength >350MPa
    Weather Resistance: Stable performance from -60℃ to 800℃
    Long Service Life: Operational lifespan exceeding 20 years

    6. Full Inspection: Withstand voltage test + dimensional inspection

    Installation Guidelines

    Professional Recommendations:

    • Clean contact surfaces with anhydrous ethanol before installation

    • Recommend using ceramic-specific adhesives for fixation

    • Fastening bolt torque should not exceed 8N·m

    • Avoid surface scratches from sharp objects

    • Regular inspection for cracks (recommended every 2 years)

    Service Commitment

    • Technical Support: Insulation system design solutions

    • Emergency Response: 72-hour rapid replenishment

    • Product Traceability: 10-year quality records available

    • Customization: Non-standard sizes and structural designs supported

    Technical FAQ

    Q: How to determine when replacement is needed?
    A: Replace when surface cracks exceed 5mm in length or 0.2mm in depth

    Q: Usage in humid environments?
    A: Recommend moisture-proof models with glazed surface treatment

    Q: Compatibility with other insulation materials?
    A: Can be used with silicone rubber, epoxy resin and other materials
