Our Versatile Transformer Rentals
Our ample selection of rental transformers can handle common and niche voltages, with a wide range of 75kVA to over 3MVA. This allows you to use step-up or step-down capabilities to match utility or generator feeds. We offer temporary and semipermanent installations with Cam-Lok or hardwire options. Units also feature tap changers to fine-tune voltage levels on-site.
Our complete temporary power solutions include equipment for multiple stages of voltage transformation, delivering power from the grid or generator to the specific voltages you need. Whether you need to match the voltage required for a temporary setup, power equipment from Europe or U.S. or need a backup while your equipment is in maintenance, we have the right transformer for you.
Medium Voltage Transformers
Our medium voltage transformers distribute power across larger sites or between different sectors of a facility. They are designed to handle the initial major step-down from high-voltage distribution and to convert between different medium-voltage levels.
These robust units offer significant power throughput. Some of the main features of our equipment include:
- kVA range of 112.5kVA to 7.5MVA
- Primary voltage range of 2.4kV to 35kV 3Ø
- Secondary 3Ø voltage ranges of 120/208V, 277/480V and 347/600V
- Hardwire and Cam-Lok cable connections
- Protective frames
- Crane, forklift and pallet jack lifting points
- NEMA 3R rated
Low-Voltage Transformers
Our low-voltage transformers ensure equipment gets the precise low voltage required to work. They take a medium voltage from a utility or lower-end medium voltage and step it down for most equipment, lighting and receptacles. Equipment options include auto-transformers for smaller voltage adjustments for specific tasks and isolation transformers that create an electrically isolated circuit within the low-voltage range.
Some key features of our low-voltage transformers for rent include:
- kVA range of 30kVA to 3125kVA
- Primary voltage range of 600V 3Ø
- Secondary 3Ø voltage range of 480V 3Ø, 120/208V 3Ø
- Hardwire and Camlok cable connections
- Protective frames
- Crane, forklift and pallet jack lifting points
- NEMA 3R rated
Advanced Protection Features for Critical Operations
Our temporary transformer rentals are built and tested to ensure safe and compliant operations. Models are housed in tamper-proof NEMA 3R enclosures that protect against harsh Canadian weather and unauthorized access on open job sites. Integrated fusing and disconnects provide robust protection. Our expert team also tests and maintains equipment before, during and after the rental period to prevent failures.
