Industrial 100KVA Three Phase Dry Type Voltage Transformer 480V To 380V Step Down

Our 100KVA three phase dry type voltage transformer is a heavy duty industrial power conversion solution engineered to step down 480V input to a stable 380V output for large scale manufacturing environments. Built on a high permeability grain oriented silicon steel core with high purity copper windings, this 100KVA transformer delivers reliable electrical isolation, consistent voltage regulation, and continuous full load operation in 50Hz and 60Hz low voltage networks up to 1000V. The oil free dry type construction completely eliminates leakage, fire, and environmental hazards while drastically reducing maintenance requirements, making it the preferred choice for plant engineers, facility managers, and system integrators who need dependable power for critical production lines. Every unit is manufactured under strict quality control and fully tested before shipment to guarantee long term trouble free service.

• High Capacity Continuous Duty: Rated at 100KVA with generous overload margin, this voltage transformer supports heavy simultaneous loads from multiple machines without voltage sag, overheating, or thermal derating.
• High Efficiency Energy Saving: High permeability silicon steel core and precision copper windings achieve ≥90% working efficiency with ultra low no load loss, significantly reducing electricity bills over the transformer service life.
• Superior Safety Insulation: F class insulation system withstands 3500V high voltage tests and 2500V dielectric strength testing, providing complete galvanic isolation that protects downstream equipment from harmonic interference and voltage spikes.
• Precise Output Regulation: ±2% output precision with an integrated digital display that monitors each phase voltage and current in real time, ensuring stable operation of sensitive industrial controllers, drives, and PLC systems.
• Rugged IP23 Enclosure: Heavy gauge steel enclosure with safety trip lock, high insulation terminals, input and output indicators, and porous heat dissipation design built for harsh factory environments.
• Eco Friendly Low Maintenance: Completely oil free dry type design complies with international environmental standards, eliminating oil leakage risks, oil sampling, and periodic oil replacement costs.

This 100KVA voltage transformer is widely deployed in heavy industry applications including automotive manufacturing plants, steel processing workshops, large injection molding facilities, central HVAC systems, mining equipment, port machinery, and high power EV charging hubs. It also serves as a dependable step down transformer for upgrading North American 480V plant networks to European standard 380V equipment, and supports customized multi tap outputs of 220V and 110V for mixed voltage facilities. The dry type construction allows safe indoor installation close to the load, reducing cable costs and transmission losses in large factories.

Each unit is packed in a reinforced non fumigation plywood case with foam cushioning; the reference packing size is 60X50X90CM with a gross weight of approximately 210KG. Our factory holds CE, ISO9001, and UL certifications, and every transformer undergoes full process quality inspection from incoming raw material to pre shipment performance testing. We offer OEM/ODM customization for voltage, capacity, enclosure color, and branding, with a minimum order quantity of one set, fast lead times, and global shipping support under all mainstream international trade terms.
