Induction Heating & Melting Capacitors

1 GE. Digital Energy Induction Heating &. Melting Capacitors All-Film and Gemvar . Product Selection & Application Guide Product Description GE manufactures water cooled and air cooled Induction Heating and Melting Capacitors with conventional all-film dielectric designs and also with Gemvar metallized polypropylene designs. We are an industry proven quality leader and supplier to major original equipment manufacturers worldwide. GE is a global supplier of water cooled and air cooled Capacitors to the Induction Heating and Melting Industry for more than 50 years with an extensive range of capacitor designs up to 4000 volts, 50 kHz and 4800 amps.

2 GE's manufacturing facility utilizes state of the art winding machines located in a clean room environment. This carefully controlled winding environment provides the highest reliability possible. That combined with our carefully controlled assembly process and fluid fill process provides for one of the highest quality and longest life products available in the industry. All Capacitors are electrically tested and tested for fluid leaks. This 100% testing in combination with our analytical data evaluation system provides for continuous process/product improvement.

3 These processes provide for some of the lowest leak rates and electrical failure rates in the industry. GE's Quality Management System is certified to ISO 9001-2008. g Application and Selection Guide Surge Capacitors & Motor Surge Protection Table of Contents Design & Application Selection of AC Water Cooled Capacitor Selection of DC Water Cooled Capacitor Ratings ..9.

4 Capacitors are designed with and without brackets, and with and All-film or metallized film dielectric without pressure switches which are utilized by equipment manufactures to Tin-plated, copper studs rated for up to 300 Amps continuous shutdown equipment in the event that pressure builds up inside the metallized design capacitor can. (See capacitor instruction GEH-2733.) Electrical grade phenolic bushings for indoor application Long life, 20 year nominal life For water cooled Capacitors , proper water flow and water outlet temperature must be maintained as specified in GEH-2733.

5 Failure to provide adequate Low loss, less than watts per kVAR up to 5 kHz; less than watts per water flow will cause early failure of Capacitors . kVAR up to 50 kHz Special dielectric system designs for high efficiency The equipment manufacturer must determine what fusing is necessary to protect Capacitors in their equipment. Protection must be provided by the GE dielectric fluids; Dielektrol V (DK-VI) for metallized dielectrics; Dielktrol equipment manufacturer to protect from re-closure or re-energization of a VII (DK-VIIa) for all-film dielectrics failed or shorted capacitor.
