5 FAQs of High Voltage 95% 99% Alumina Vacuum Metallized Ceramic Tube

What is a High Voltage 95% 99% Alumina Vacuum Metallized Ceramic Tube?
This ceramic tube is designed for high-voltage applications. It’s made from alumina (95% or 99% purity) and processed via vacuum metallization. This method coats the surface with a metal layer. The result is a component that combines ceramic insulation with metallic conductivity in specific areas. It’s used where electrical performance and durability matter.

Why does the alumina percentage matter?
Higher alumina content (99%) improves insulation and heat resistance. It handles extreme temperatures better than 95% alumina. Lower alumina (95%) costs less but offers slightly reduced performance. The choice depends on application needs. High-purity alumina is preferred for critical high-voltage environments.

Missä tätä keraamista putkea tyypillisesti käytetään?
It’s common in high-voltage equipment like insulators, capacitors, and circuit breakers. Industries include power transmission, aerospace, and electronics. The tube’s insulation and thermal stability make it reliable in harsh conditions. Vacuum metallization ensures precise conductivity where required.

How does it compare to other insulating materials?
Traditional plastics or metals lack the same heat resistance. Ceramic handles higher temperatures without degrading. Vacuum metallization adds controlled conductivity without sacrificing insulation. This balance is hard to achieve with other materials. Ceramic also resists corrosion better than metals.

Onko näiden putkien käsittelyyn liittyviä varotoimia?
Yes. Avoid mechanical impact—ceramic is hard but brittle. Sudden temperature changes may cause cracks. Store in dry conditions to prevent moisture absorption. Use proper tools during installation to avoid surface damage. Follow manufacturer guidelines for electrical connections to maintain performance.
