Sulfr hexafluoride: No Leak Too Small | TD World

An Alliance PartnershipModern GIS AdvantagesReplacement SuccessAbout ITC Holdings Corp.Implementing a business strategy, ITC Holdings Corp. — including its subdivision ITCTransmission— entered into an alliance partnership with Mitsubishi Electric Power Products Inc. (MEPPI; Warrendale, Pennsylvania). Although there is nothing revolutionary about the companytight manufacturing tolerances, simple proven designs and attention to detail during assembly (especially with single O-ring seals and sealant products), MEPPI has developed a reputation for high-quality products with the lowest overall cost of ownership. Choosing to partner with MEPPI made sense to ITC for a variety of reasons. An important design feature required for new circuit breakers was that the mechanisms driving the interrupters not rely on pneumatic or hydraulic pressure. ITCpast experience with the inherited air-blast and hydraulically driven circuit breakers was that these systems required frequent maintenance and repairs. Also, earlier versions of gas breakers and other equipment using Sulfr hexafluoridehad a le...Get price
