Pioneer Introduces New Medium Voltage Transformer/Interrupting Switch Assembly

Pioneer Dry Type Group introduces Medium Voltage Transformer/Interrupter Switch Assemblies which provide safe, reliable and cost-effective switching and fault protection for unit substations. Designing and manufacturing the fully integrated switch and transformer together ensures that the components work together. On-site assembly is simplified since all components are factory-tested as a single unit. Disconnected for delivery, all applicable cables are provided and clearly marked for reconnection. Full load current interrupting capability combined with accurate, calibrated fuse protection makes these designed-together packages ideal for industrial, utility and commercial applications.

Available in 5KV and 15KV class models, for 600A or 1200 Amp Continuous Load interrupting rating, these value-added products enhance the extensive Pioneer product offering. The new Transformer/Interrupting Switch Assembly provides customers a choice of market leading switch manufacturers, with or without fusing, NEMA 1 or 3R enclosures and switch orientation on the right or left side of the transformer. Custom designs for specific applications available. All Pioneer Medium Voltage Transformer/Interrupting Switch Assemblies meet IEEE, ANSI, UL, and CSA standards/certifications.

A wide range of options are available, including Kirk Key interlocks, 4? infra-red window, current limiting fusing, blown fuse indicator, fuse clips, spare fuse pocket, thermostat, strip heater, surge arrestors, insulated bus, ground ball stud w/cover, indicator lights, and more.

Pioneer Dry Type Group has been an innovator in magnetic products since 1915, with extensive experience and success in commercial, industrial and OEM markets. Pioneer companies produce over 100,000 transformers a year. This large-scale production and demand driven scheduling help keep purchasing costs of material low and production responsive.
