Overview of Our Special Isolation and Winding Techniques

Considering our focus on quality and accuracy, we use the best high voltage transformer winding techniques. When winding high voltage transformers, it is important to consider their function aside from their insulation and capacity to withstand voltage changes. The field of high voltage transformers extends from very large power grid type transformers down to very small high voltage trigger transformers. Regardless of the type of transformer you choose, Custom Coils uses specially-developed techniques to isolate and insulate transformers to eliminate the possibility of a breakdown under load.

We do this by isolating the primary from the secondary and also the secondary from the ground. This process begins with the selection of an optimum winding technique for the design. At Custom Coils, high voltage winding is carried out either on a multi-section bobbin or on a multi-layer coil form. We insulate multi-layer windings with the help of quality insulation materials such as Kapton film, Nomex, Teflon, and other similar materials.

Custom Coils also specializes in the implementation of the universal Pi wind, a highly specialized winding technique that is used if inter-winding capacitance is a concern. This basket-weave style winding is  now becoming obsolete but demonstrates great performance in high voltage transformer applications.

To make the high voltage transformer design more robust, Custom Coils uses one of several different electrical-grade varnishes to impregnate and further improve the insulating properties of the coil. Finally, to help mitigate high voltage problems with outside components in an assembly, we have the ability to encapsulate our designs in one of several high-quality epoxies.

As an experienced high voltage transformer manufacturer, we offer plenty of customization to suit your requirements. You can share your requirements or design with us and our team would be happy to help you.
