Pad-Mounted Transformers
The safety and security of tamper-proof padmount transformers make them ideal for public installations with underground cabling.
Our three-phase pad-mounted transformers primarily consist of the
following components:
·1″ Upper Fill Valve
· Bayonet Fuse
·Breaker
·Dead-Front Arrester Elbow
·Drain Valve
·Feed-Through Insert
·High-Voltage Bushings
·Load-Break Insert

Frequently Asked Questions
Can three phase pad mounted transformers be customized for specific projects?
Yes. Transformers can be customized based on project specifications, including voltage ratings, vector groups, switching configurations, protection devices, and enclosure designs.
Do you provide technical support for transformer selection and installation?
Yes. Our engineering team can assist with transformer selection, technical documentation, and installation guidance to ensure the transformer meets your project requirements.
What tests do your pad mount transformers undergo before leaving the factory?
We conduct a full range of tests—including winding resistance, turns ratio, corrosion detection, and AC withstand voltage—and provide comprehensive reports that comply with IEEE/ANSI standards. You are also welcome to visit our facility to witness the product testing in person.
How do CSA-standard three-phase pad-mounted transformers differ from IEEE-standard pad-mounted transformers?
These two standards specify different transformer capacities.
• CSA standards: 3000 kVA, 34.5 kV and below.
• IEEE standards: 10000 kVA, high voltage 34.5 kV, low voltage 15 kV and below.
How do I select the right three phase pad mounted transformer for my project?
Selecting the right transformer depends on several factors, including required power capacity, system voltage, load characteristics, and distribution network design. Our engineering team can help evaluate your project requirements and recommend the appropriate configuration.
