You have made a great decision to learn more about epoxy resin transformers. You have searched for this keyword on Google, only to realize that the information available is somewhat incomplete. Only a few of its main features are well known. One, in particular, is its minimal fire risk because of its zero oil usage.

In this article, we will dig deeper into the main characteristics of this type of current transformer. Grab yourself a cup of coffee and get your notebook ready to take notes. Let’s start!

  • Safety and Eco-friendliness:

With an epoxy resin current transformer, you will not incur any risks for oil leaks and pollution of the environment. During normal operations, it’s highly unlikely to encounter transformer explosions. An epoxy resin current transformer is usually made with self-extinguishable and non-toxic substances. This means that you will be protected even in the case of external fires.

This type of current transformer is also very suitable for heavy condensation and polluted environments. Indeed, an epoxy resin current transformer can withstand even the most sudden changes in the environment. For example, it can work perfectly well and go immediately from -25ºC to +40ºC in a short time.

  • Low Fire Risks and High Fire Self-extinguishing Capabilities:

The insulation of an epoxy resin current transformer is made of a mixture of epoxy resin and quartz powder. The second one is a very eco-friendly material. This mixture allows the current transformer to be self-extinguishing and flame-retardant. It almost requires no maintenance, besides the fact that you won’t need any costly fire extinguishing equipment anymore. An epoxy resin current transformer will also not produce toxic gases, not even if under the effects of arcing.

  • No Use of Oil:

Besides all the other qualities we have just mentioned, the epoxy resin current transformer also needs only air to cool. This means that you can say good-bye to the extra costs and labor that you would need for oil testing, liquid-level checking, oil recycling, and dielectric testing for moisture absorption. Since this type of current transformer is almost maintenance-free, you won’t need to worry about on-site oil leaks and eventual replacements.

  • Low Load Losses and Installation Costs:

With an epoxy resin current transformer, there are almost no restrictions on the installation site. There will also be no groundwater protection costs during the site preparation phase. In particular, when the transformer is closer to the load, you will have to face lower cable losses and other related costs.

  • High Reliability:

An epoxy resin current transformer has a life span of at least 20 years. It also has a low failure rate, primarily when it’s operated within its designed parameters. This aspect makes it a reliable component of any electrical infrastructure.

  • Not High Maintenance Needed:

An epoxy resin current transformer only needs some air to cool. Nowadays, liquid testing has already become obsolete. This type of current transformers eliminates massive dirt build-up, regardless of how extreme the circumstances are. When it comes to maintenance, we recommend your technical personnel performs routine visual inspection and eventually wipe down the transformer if needed.
