Formed wedges are insulation composite materials that are generally made from polyester, aramid papers, or vulcanized fiber and are generally used as cool operators, liners, wedges or phase insulation materials. They are typically used as primary layers or outer wrap insulators for transformers or in sealed motors. Essex Brownell is dedicated to a leadership position in formed round and square wedge production, offering a complete range of materials, shapes and sizes. We also offer custom materials and services to meet specifications. Formed wedges in DMD, ELAN-film, Nomex, Pet Film and TFT are among the most common selections but Essex Brownell can advise on making the right choice for your application depending on the many factors that you are considering for the project.
