The Pad Mounted type electrical transformers are essential equipment for the distribution of energy between the different establishments of the country. Well, energy is essential for the operation of shops, buildings, shopping centers, etc. To this is added the concern for the supply of renewable and safe energy that increases the need for this surface distribution equipment.

Benefits of Pad Mounted Transformers

Pad mounted transformers were developed in the late 1960s. Its design was mainly a standard equipment equipped with a cabinet for better and optimal external protection.

From that moment, a before and after was marked in power distribution transformers, offering benefits for both users and the environment:

Technical information

The pad mounted transformers are suitable for both indoor and outdoor installation. They are used for underground distribution, with low and high voltage compartment. This transformer is placed on top of a base or a pedestal.

The Pad Mounted are designed to work outdoors, that is to say, outdoors. They are highly efficient equipment, self-cooled and bathed in silicone, vegetable or mineral oil.

These equipment are well designed for tough work and in contaminated areas. In addition, it supports up to 5,500 meters above sea level during its operation.


The pad mounted transformer is a substation that integrates medium and low voltage protection. It has an enveloping structure that makes it possible to install it at the height of the floor without the need for a protection fence. On the other hand, it is designed in a compact way as long as it takes up as little space as possible.

These transformers are suitable to be installed in hospitals, schools, public spaces or shopping centers, thanks to their careful aesthetics and highly protected design.

They can also have medium voltage and low voltage thermomagnetic switches. It has the same standard accessories as a normal distribution transformer; however, additional elements can be added such as instruments with alarm contacts.

Pad Mounted can work more harmoniously with the environment if they are designed to work with biodegradable vegetable oil.

The pedestal or pad mounted transformer is available in various types of formats that vary depending on their electrical power.

  • Pad mounted 300 kva transformer
  • Pad mounted transformer 500 kva
  • Pad mounted 750 kva transformer
  • 1000 kva pad mounted transformer
  • Pad mounted 1200 kva transformer

In addition, all of them integrate the following elements that make them highly effective teams:

  • Sliding base for indestructible cladding.
  • Medium voltage bayonet or canister type fuses
  • Medium voltage connection plugs
  • Ground bar
  • Low voltage insulators.
  • Overpressure valve.
  • Insulating liquid level indicator
  • Thermometer

Transformer maintenance: What is it based on?

Its maintenance is based on monitoring this electrical machinery during its useful life, in order to get the most out of it and predict future problems so that production losses are minimal.

To be more specific, this monitoring aims to fulfill:

  • Reduce the risks of fire and electrocution.
  • Extend its useful life.
  • Avoid interruptions in the circulation of energy.
  • Produce significant savings for the company.
