Overview and Basic Structure

The helical ceramic break/isolator is an insulating pipe specifically designed for providing electrical insulation when introducing gases into a system. The spiral flow channel is made of alumina ceramics, ensuring excellent electrical insulation and mechanical strength. KOVAR caps are bonded on both ends to enhance structural integrity and facilitate secure connections. A stainless steel pipe is attached at the tip and is directly connected to the gas flow path. However, for customized applications, the pipe material can be modified to meet specific requirements.

Ideal for insulating applications in spacecraft propulsion systems

The spiral/helical ceramic break/isolator has a proven track record of being used in spacecraft propulsion systems such as ion thrusters, particularly Hall thrusters, where xenon (Xe) gas is commonly used as the propellant. As a crucial electrical isolator, it ensures reliable insulation in these propulsion systems, which power spacecraft and satellites in orbit.

Enhanced insulation performance in limited space

Despite its compact size, the helical ceramic break provides a long insulation distance in environments where space is severely restricted.
The insulation distance can be increased 2-3 times compared to straight-shaped ceramic breaks/isolators of the same length, making it ideal for spacecraft and satellite applications where every inch of space matters.

Versatile applications

While ideal for use in Hall thrusters and other spacecraft propulsion systems, the helical ceramic break also has proven applications in various semiconductor manufacturing systems, including CVD and sputtering systems, as well as etching/film deposition apparatus. It is particularly used for insulation when introducing process gases.

High Resistance to Leakage and Corrosion :
Specially designed for liquid applications.

Our Ceramic Breaks(liquid type) are specially designed for the transmission of liquids.
The inside structure is smooth, which can effectively prevent the liquid from staying inside even when the flow stops. (As the Image below)

The varying thermal expansion of different materials can cause cracks on the surface of ceramics. To prevent the ceramic parts from cracking, many companies will leave a gap on the joint part to relax the thermal stress.
Instead of leaving a gap on the joint, we created a less susceptible design to thermal stress, and our special brazing technology allows our product to be excellent in corrosion resistance to pure water.
