Capabilities:

Being a world-leading high-voltage mica capacitor and high-voltage assembly manufacturer for more than 45 years, we have developed a long list of capabilities which allow us to produce some of the most reliable high-voltage products available. We’re confident we have the experience and know-how to meet your needs. Here are only a few of the capabilities that help set us apart from the rest:

3-D CAD (Computer Aided Design)

CEI utilizes SolidWorks solid (3-D) modeling software. The use of 3-D modeling software dramatically shortens the design cycle and reduces fabrication errors. Our engineers and designers are experts in 3-D mechanical design and welcome the opportunity to help design your next multi-layer bus bar. If you wish to supply an existing solid design to have quoted for production, please use .IGES, .STEP or native SolidWorks file formats.

3-Dimensional Printing (Fused Deposition Modeling)

Nothing communicates design ideas better than a functional 3D model. They enable the designer to make better informed decisions resulting in: fewer design changes, better product designs and lower overall costs. Our 3D FDM capability will bring your CAD files and design ideas to life allowing you to test form, fit and mechanical function earlier in the design process than ever before.

High Dielectric Strength Powder Coating

We take great pride in our high dielectric strength powdercoating capability. We can accommodate bus bars up to 24” x 12”. Our epoxy powdercoating has a dielectric strength of 1200v/mil and can be applied in thicknesses from .008” to .060”. Our proprietary masking/de-masking process yields silky smooth and robust coating terminations. Our coating survives thermal cycling and from -67°F to +500°F and greater than 100 of hours at 500°F without degradation.

Large Scale Epoxy Vacuum Molding

Another unique strength is our ability to mold specialized epoxies into large scale and highly detailed shapes. With more than 120 years of combined experience, our mold engineers have developed some of the most complex molds imaginable. If you have a bus bar assembly requiring dependable high-voltage barriers, threaded inserts or large connector shrouds, this is the best way to do it.

Electrical and Environmental Testing

CEI has continually increased its test capability to accommodate a wide variety of electrical and environmental test requirements. Our highly skilled engineers welcome the opportunity to design and build new test circuits and fixtures to suit our customers' needs.
