1,000 kVA Medium Voltage Dry Type Transformers

At 1,000 kVA, the electrical and mechanical stresses placed on a transformer’s core, windings and insulation system are substantial. Sourcing a replacement demands a unit engineered with the construction precision and material integrity to handle high-capacity service reliably for decades. ELSCO Transformers stocks medium voltage, 1,000 kVA dry type transformers built to this standard. Our emergency replacements leave our facility within 24 to 48 hours, depending on what modifications need to be made.

1,000 kVA Dry Type Transformer: Overview and Features

Since we began manufacturing our own dry type units in 1988, we have recorded zero product failures or warranty claims due to our materials, workmanship or design. This commitment to quality is reflected in our transformers’ long service life, which is often over 35 years. We also stand behind our solutions with a five-year warranty for new indoor dry type models and a three-year warranty for remanufactured transformers.

Every coil is hand-wound, and each completed unit clears five sequential production checkpoints before leaving the floor. Our solutions consistently achieve a power factor of approximately 0.3%, which is below the 1% industry benchmark.

Transformer Construction and Materials

Our design features a round coil primary over a step lap mitered core, a geometry that manages flux density to minimize core losses and operating temperature. The secondary windings are sheet-wound, enhancing short-circuit strength to withstand major fault events common in high-capacity industrial and commercial electrical systems.

Both primary and secondary windings are 100% copper. At 1,000 kVA, copper’s superior conductivity and lower resistance result in higher efficiency under load and reduced heat generation, contributing to a longer, more reliable service life.

The transformer coil is protected by an insulation system featuring DuPont Nomex and SG200 fiberglass. This construction provides a high thermal and dielectric protection, reducing insulation breakdown under the high operating temperatures and electrical stresses of continuous 1,000 kVA service.

Installation Support for a 1,000 kVA Transformer

ELSCO Transformers can engineer your replacement transformer for a seamless retrofit. Our team verifies critical dimensions and connection points against your existing infrastructure, enabling a plug-and-play design that shortens installation time. Where needed, we fabricate custom bus bars to minimize the need for on-site modification and installation complexity. Our team is available 24/7 to answer installation questions via phone.

Locally Produced Systems for Diverse Applications

Our 1,000 kVA transformers serve different industries such as:

• Heavy manufacturing and process facilities: Drive full production environments with continuous high-ampere loads distributed across multiple automated lines.
• Large hospital and healthcare campuses: Power critical care, surgical and support infrastructure across multibuilding medical campuses operating 24/7.
• Data centers and technology infrastructure: Sustain the dense, continuous electrical draw of server rooms and network operations centers where voltage stability is nonnegotiable.
• Higher education central utility plants: Deliver distribution capacity for large university campuses with centralized power infrastructure serving academic, residential and administrative buildings.
• Large commercial high-rises and mixed-use developments: Provide step-down capacity for high-density properties where aggregated tenant demand often exceeds the range of midtier transformer configurations.
