250 kVA Single-Phase Pad-Mounted Transformer

It may be considered for larger residential, commercial, institutional or utility projects when supported by the system design, load calculation and utility requirements.

250 kVA Single-Phase Pad-Mounted Transformer: Listed Product and Project Requirements

• Listed Capacity: 250 kVA
• Phase: Single-phase
• Product Type: Liquid-filled pad-mounted distribution transformer
• Installation: Outdoor, pad-mounted

Requirements to provide for engineering review

• Frequency: State the required site frequency, including 60 Hz where specified by the project.
• Primary Voltage: Provide the system voltage, phase-to-neutral voltage where applicable, grounding arrangement and utility specification.
• Secondary Voltage: State the required output voltage and connection arrangement.
• High-Voltage Interface: State any dead-front or live-front requirement and the required cable interfaces.
• Tap Requirements: Provide the specified tap range and increments, or mark TBC for review.
• Feed Arrangement: State the radial-feed or loop-feed requirement.
• Insulation Level: Provide the required BIL and primary voltage class, or mark TBC for review.
• Insulating Liquid: State any specified liquid and relevant environmental or fire requirements.
• Standards and Edition: Provide the project or utility specification. If IEEE C57.12.38-2025 is required, its scope and the proposed equipment must be reviewed together.

These inputs define the requested equipment. Available configurations, conformity, test evidence and supply scope require confirmation for the proposed design. A standard reference alone does not establish product conformity.

Applications

This rating may be considered for high-capacity single-phase loads in larger residential developments, commercial sites, institutional facilities and utility distribution systems.

Selection of a 250 kVA transformer must be supported by the project load study, system voltage, protection coordination and utility requirements.

Request a 250 kVA Single-Phase Pad-Mounted Transformer Quotation

Provide complete electrical ratings, quantity, feed arrangement, BIL, terminal requirements, protection devices, accessories, environmental conditions, destination country and applicable standards.

What should accompany a 250 kVA RFQ?

Include the load study or load schedule, system voltages, protection requirements, and utility specification. State the required tests and documentation. The requested capacity does not by itself establish suitability for the proposed distribution system.

Engineering Review

The voltage ratio, insulation coordination, taps, terminal configuration, enclosure, insulating liquid, protection scheme, accessories and applicable standard will be reviewed for each project.

The product image illustrates this transformer family. Final enclosure dimensions and terminal layout must follow the approved project drawing.
