In the tough, unforgiving world of heavy industry, downtime isn’t just the enemy, it’s catastrophic. Whether you’re running the conveyors at mining site, the massive induction furnaces in steel mill, the intricate networks pumping in tons of purified water or the specialized chillers keeping server rooms at just the right temperature, your industrial equipment has to operate at full throttle on steadfast supply of electricity. That means having not just electricity, but stable, potent, and incredibly reliable source like three-phase transformer. For decades, Jiangsu Ryan Electric Co., Ltd., through our joint venture with Eaton, has focused solely on optimizing the designs of three-phase transformers, from dry-types and VPIs to those that run oil-immersed or in pad-mounted designs. Now you can deliver reliable, three-phase electrical performance at full power to your heavy industrial machines.
Balanced Power Delivery for High-Starting-Torque Motors
Heavy industrial machines like pumps, compressors, extrusion presses and crushers have huge initial starting torque requirements. Single-phase systems, just do not have enough continuous torque to spin up heavy machinery like this without voltage sag or causing excessive mechanical stress to the machine components. Three-phase transformers, of course, present balanced overlapping electrical waveform that will be smooth and smooth enough into any Induction motor without excessive vibration and wear on the couplings or the motor shaft, and certainly do not have problems with false relay trip-ins.
When it comes to our VPI or cast resin power and distribution transformers, we build in low impedance and high short circuit capabilities to support all of your stop and starts, including the three phase oil immersed transformer and unit substation transformer options rated up to 10 MVA at voltages 3.3 kV to 132 kV. This also allows torque to remain at an acceptable level so your production line isn't held back.
Superior Fault Tolerance and System Stability
A fault in heavy industry setting is also to be expected. Whether by way of lightning strike, switching surge, motor inrush current, or merely an intermittent overload, one or two of the phases could be suffering an issue. In three-phase transformer arrangement, a three-phase transformer, on account of having three physically separated legs, balanced number of windings and being capable of use with either wye or delta connection will be far more tolerant of individual faults or transient events than bank of single phase transformers. The magnetic interaction of the legs will help isolate the fault without degrading the voltage to the healthy legs.
35 kV and 110 kV twin, CNAS laboratory are all able to do test work. All manufactured transformers undergo rigid testing against standard such as IEEE, IEC, UL, CE, ASTA and DEKRA. From small substation transformers for remote pumping stations to large pad-mounted units for grid interface, every transformer undergoes our quality management process—from raw material inspection to routine, type, and special tests.
Optimal Efficiency under Continuous Full-Load Operation
While commercial building loads may ebb and flow throughout the day, many heavy industrial applications continue to operate 24-hours day with close to full power usage. For such applications with heavy, continuous duty cycles, transformer efficiency becomes vital since loss in efficiency of just 0.5% can lead to thousands of dollars wasted on energy each year. A major advantage of the three-phase design is its inherently higher efficiencies over single phase since three phase designs inherently involve smaller copper losses (CLs), lower core losses and more effective use of the magnetic material to transfer power. Furthermore three phase systems allow more compact three conductors, for equivalent power transfer—reducing I²R losses and improving power factor.
At Jiangsu Ryan Electric, our R&D team creates custom three phase solutions to reflect your operation’s precisely. We can specify everything from VPI transformers featuring the high temperature resistance offered by Class F/H insulation, to outdoor substations powered by oil-immersed transformers utilizing both ONAN/ONAF cooling systems. We optimize every core design, winding layout and tap changing range to reduce no-load and load losses in your system. Already exported to more than 80 countries across the Americas, Southeast Asia, Middle East, Africa, and Europe-we make productivity predictable for Microsoft, State Grid, and companies across the globe who trust our three-phase dry-type and power transformers.
Scalability and Modularity for Expanding Industrial Sites
The pace of heavy industrial operations almost never stands still. New product lines, added motor drives and surge in processing capacity add up to growing need for electrical infrastructure that can expand, not explode. Three-phase transformer designs provide the flexibility to scale from 3.3 kV up to 35 kV over miles of single-phase feeder, or from 110 kV down to 6.6 kV for new high voltage motor bank. Browse our catalog with more than 20 series of transformer options, single phase pad mounted to split-phase, outdoor power to triple phase distribution; full substation turnkey systems featuring dry type or oil immersed designs integrated with switchgear and metering.
Our globally proven expertise in renewable energy, energy storage, utilities, and infrastructure assures we know the challenges of your site-whether it involves space, environment, or operations. Our custom solutions cover everything from seismic-hardened to high-altitude or tropicalized enclosures, all with the support of our knowledgeable engineering team. With our ISO certifications in place (UL, ASTA, CSA, CE, DEKRA, D-U-N-S Registered, and CNAS)-you can rest assured the transformers you rely on will adapt.
