What is the pad mount transformer?

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. A single transformer may serve one large building or many homes.

Pad-mounted transformers are made in power ratings from around 15 to around 5000 kVA and often include built-in fuses and switches. Primary power cables may be connected with elbow connectors, which can be operated when energized using a hot stick and allows for flexibility in repair and maintenance.

Applicable places for pad mount transformers

1. Used as street light pad-mounted transformer:

Both European-style pad-mounted transformer and American-style box transformers have advantages over traditional civil-construction power houses in small-load power systems. Because the cost of box-type substations is much lower than that of ordinary power rooms, the appearance is also very beautiful. European-style box substations can also use landscape-type casing, which is a beautiful scenery.

2. Electricity consumption in parks and communities:

Box-type substations are often used to supply power in parks, communities and other places. Parks and communities often pursue beauty and space occupation. Box-type substations solve these two problems very well, with beautiful appearance and small footprint.

3. Industrial and mining electricity consumption:

Factories, mines and other areas have high requirements for power supply equipment due to complex terrain and expensive time costs. The box-type substation is easy to install, requires less on-site construction, and has a protection level of IP33, which can greatly reduce the construction volume and construction period and can be installed in areas with complex terrain.

4. Temporary electricity use:

Construction units often change the location of power consumption as the construction site moves, so they need a set of mobile power distribution equipment. Box-type substations have good mobility and large enough load capacity to fully meet the temporary power demand on the construction site.
