3,500 kVA Medium Voltage Dry Type Transformers

ELSCO Transformers hand-builds 3,500 kVA medium voltage dry type transformers using 100% copper windings and premium insulation materials to decrease your total ownership cost. Your system can be ready to leave our production floor within 24 to 48 hours, based on the modifications your installation requires.

What Goes Into Our 3,500 kVA Transformer

ELSCO designs and builds transformers with these factors in mind: installation costs, energy costs, maintenance costs and service life. Every construction decision, from the winding method to insulation material selection, is made to minimize the first three and extend the last.

The primary windings feature a coiled design, while the secondary is sheet-wound, delivering a BIL rating comparable to liquid-filled systems. This construction provides inherent short-circuit protection and maintains coil geometry under fault conditions, helping protect your investment when the system is under significant mechanical stress.

Tight mechanical assembly, compliance with airflow clearance specifications and lower magnetic induction designs keep operating temperatures and acoustic output low even at full rated load. Cooler operation minimizes hot spots and insulation stress, extending the interval between maintenance schedules. ELSCO transformers offer a service life of more than 35 years.

Other features include:

• 100% copper windings: Copper conducts electricity better than aluminum, making it suitable for short-circuit strength. This characteristic supports better performance and a longer operational life under sustained load.
• Moisture-resistant construction: The coil and core build is resistant to moisture, supporting reliable operation in adverse environmental conditions.
• Reduced vibration: Anti-vibration pads are incorporated into the design to minimize noise and mechanical vibration during operation.

Providing Site-Ready Transformers

We can retrofit your transformer to match your existing setup. Our team considers enclosure size, connections, electrical clearances and other factors to facilitate a plug-and-play installation. If you require custom bus bars, we can fabricate them to ensure alignment with your existing infrastructure, eliminating the need for costly on-site modifications. If any questions arise during installation, call our engineers for guidance — we are available 24/7.

Industries That Can Benefit From Our 3,500 kVA Units

The 3,500 kVA rating serves operations where high sustained loads and zero tolerance for unplanned outages define the power requirement. Common applications include:

• Large-scale food and beverage processing: Power continuous refrigeration systems, processing lines and facility HVAC operating under full electrical draw across round-the-clock production cycles.
• Military installations and defense infrastructure: Provide high-capacity power for mission-critical systems where reliability carries operational and security consequences.
• Major urban transit and rail terminals: Deliver centralized voltage conversion for traction equipment, station HVAC, fare and access control systems and emergency power across high-throughput passenger facilities.
• Steel service centers and heavy metals distribution: Support high-draw equipment such as slitters, levelers and cut-to-length lines, where consistent voltage is critical for motor performance and the precision of electronic controls.
• Large institutional and mixed-use campuses: Distribute medium voltage power across properties combining diverse load types for office, residential, retail and institutional environments under a single distribution infrastructure.
