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
