A padmount or pad-mounted transformer is a ground mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformer can be installed in places that do not have room for a fenced enclosure. Padmount transformers are used with underground electric power distribution lines at service drops , to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers.
Pad-mounted transformers are made in power ratings from around 75 to around 5000 kVA and often include built-in fuses and switches. Primary power cables are connected with elbow connectors, which can be operated when energized using a hot stick and allows for flexibility in repair and maintenance.
Figures
You know the components that make up a conventional substation: a transformer and a separate set of
switchgear or cut-out fuses with disconnector.
Just think about it: the total costs incurred by buying a transformer and switchgear separately—including
warehousing, transporting, installing, maintaining and retiring—far outweigh any “deal” you think you might be getting at the time of their purchase.
Sure, a transformer and separate switchgear might be the conventional solution to power distribution… but if you think it’s the cost-effective solution, better think again.

Why choose us
| Hunan Electric Union is a diverse electric equipment manufacturer group located in middle south of China. |
| Limit Innovation |
|
We are in a traditional business since transformers and switches are developed over hundred years, even
the so called “new technologies” of cast resin technology, vacuum arc distinguish technology and digital
policy on our mature products |
|
1. Update products only if latest standards revision officially issued
2. Produce new products only if related technology are maturely developed. 3. Focus limit innovation on external updates to make products easy to use and transport. |
| Our Mission |
|
progress, the manufacturing industries have gradually entered a world-class level, and many well-known
international companies
have chosen to set up factories in China.
so our mission is to provide the most cost effectiveproducts to world,
and these products are transformed to meet relevant international
Eventually, we could help the developing regions to update their energy quality and improve people’s life. |
