Pad Mounted Transformer

Pad Mounted Transformer

The pad mounted transformer serves as a grounded power distribution system utilized outdoors or underground. Enclosed within pad-mounted units, these distribution systems eliminate exposed wires or cables, making them ideal for deployment in high-traffic and communal areas. This design feature not only obviates the need for fencing but also reduces wiring needs, resulting in cost savings and more dependable power connections. With a service life of 25-30 years, these transformers offer long-lasting reliability.

The pad-mounted transformers engineered and manufactured by Daelim Transformer adhere to stringent standards such as IEEE C57.12.4 and CSA C227.4, while also meeting efficiency requirements set by DOE and CSA. Customizable according to project specifications, our transformers can withstand harsh environments, including corrosion protection, low-temperature rise, and other demanding conditions, along with accommodating special design requirements.

Pad Mounted Transformer Tests & QC

Pad Mounted Transformer Tests & QC

After each unit of Daelim Transformer's pad-mounted transformer is produced, routine tests/FAT will be conducted following the requirements of ANSI/IEEEC57.12.90 and C57.12.00. The test report complying with IEEE/CSA standards will then be issued.

We offer both online and offline test supervision options for our customers. You can choose to have a third party, such as SGS, CSA, or UL, visit the Daelim Transformer factory during the testing phase to witness the tests being conducted and receive a report that fully complies with standard requirements. Alternatively, you can opt for online video monitoring to observe the testing process in real-time. Ensuring transparency and confidence in the testing procedures.

Our production and testing equipment undergo professional calibration every year. The UL agency also supervises and inspects our factory every three months. These measures ensure that Daelim Transformer produces high-quality, safe, and reliable transformers.

Live front & Dead front transformer

Daelim Transformer offers the flexibility to design and produce both live front and dead front pad-mounted transformers to suit your specific requirements.

Dead Front Transformer: In a dead front transformer, the high-voltage bushing is separate, comprising a bushing well and a load break bushing insert, both insulated. High-voltage cables connect to the transformer using a dead break elbow connector, ensuring no exposed electrical components in the energized high-voltage section. This design significantly reduces the risk of accidental contact or electric shock.

Live Front Transformer: In a live front transformer, the high-voltage bushing typically consists of a one-piece spade type made of materials like porcelain or epoxy, often with 2-4 holes at the end. High voltage cables connect to these holes using a mechanical lug or a crim plug. Unlike dead front transformers, the high-voltage bushing in live front transformers is fully exposed, potentially leading to safety concerns if moisture, oil, or dust is present, increasing the risk of arc generation.

Based on our extensive experience, most customers opt for the dead front pad-mounted transformer due to its superior safety features. However, the choice ultimately depends on your specific needs and preferences. Rest assured, Daelim Transformer can tailor our solutions to meet your project requirements.
