Specification of Resistant High Temperatures Alumina Conical Metallized Insulator Rollers for Vacuum Interrupters

These alumina conical metallized insulator rollers are special parts made for vacuum interrupters. They handle high heat and provide electrical insulation. People use them inside vacuum chambers where electrical switching happens.

The rollers are built from alumina ceramic. Alumina is very hard and keeps electricity from flowing through it. It stays strong even when things get extremely hot. We use high-purity alumina for this job. This purity makes the insulator reliable and long-lasting.

The shape is conical, like a cone. This cone shape helps position parts inside the vacuum interrupter correctly. It guides the moving parts smoothly. Good alignment is essential for the interrupter to work right every time.

A thin layer of metal covers the conical surface. We usually use nickel for this metal coating. The coating lets us attach the roller to other metal parts. We solder it on using a special high-temperature method called brazing. This creates a tight seal and a solid connection.

These rollers come in specific sizes. The diameter can vary depending on the vacuum interrupter model. Common sizes range from 10 millimeters to 50 millimeters. The length also changes based on the design needs. We make them to fit different manufacturers’ requirements.

Resisting high temperatures is their main job. Vacuum interrupters create intense heat when switching electrical currents. These alumina rollers withstand temperatures over 1000 degrees Celsius. They do not melt or crack under this heat stress. This keeps the vacuum interrupter working safely.

The alumina material is an excellent electrical insulator. It stops electricity from leaking where it shouldn’t go. This insulation is vital for the vacuum interrupter’s performance. It ensures the electrical path is controlled and safe. The metal coating only covers the surfaces meant for connecting.

5 FAQs of Resistant High Temperatures Alumina Conical Metallized Insulator Rollers for Vacuum Interrupters

Here are five common questions about resistant high temperature alumina conical metallized insulator rollers for vacuum interrupters. Why choose alumina for these rollers? Alumina handles extreme heat very well. It keeps its strength even at very high temperatures. This material also resists wear over time. This makes it reliable for demanding vacuum interrupter applications.

How hot can these rollers get? These rollers withstand temperatures exceeding 1500 degrees Celsius. They stay stable and strong. They won’t crack or warp under heat stress. This high temperature resistance is essential for vacuum interrupters working in tough conditions.

Do these rollers work well in a vacuum? Yes, alumina performs excellently in vacuum environments. It doesn’t release gases easily. This prevents contamination inside the vacuum chamber. The material stays reliable under vacuum pressure conditions.

Why is the roller surface metallized? The metallized coating provides electrical conductivity. It allows electrical currents to flow where needed. This coating bonds strongly to the alumina base. It ensures good performance without peeling off.

What care do these rollers need? Maintenance is simple. Regular cleaning keeps the surface free from dust and debris. Inspect them for any damage or wear periodically. Handle them carefully to avoid chipping the alumina or coating. They are built for long service life with minimal upkeep.
