They are ideal for outdoor installations and highly polluted environments. Additionally, they typically have a more efficient thermal dissipation capacity at high power ratings and a more competitive initial cost.
Oil-filled Transformer
Manufacturing
With over 60 years of leadership, at MIRON we manufacture highly reliable oil-filled transformers. From distribution and power equipment to custom engineering projects, our solutions guarantee robustness against overvoltages and superior operational efficiency, meeting the most demanding standards of the global industry.
Distribution Transformers
Distribution transformers are electrical devices designed to step down voltage from power transmission systems to lower levels suitable for residential, commercial, and industrial applications. These transformers distribute electricity from medium-voltage networks to low-voltage levels, ensuring safe and efficient delivery to end users.
Technical Specifications
- Power ratings from 63 kVA up to 2,500 kVA.
- Nominal voltages: Medium Voltage from 13.2 kV to 33 kV; Low Voltage 0.4 – 0.23 kV.
- Aluminum or copper windings.
- Compliance with IRAM, IEC, and ANSI standards.
- Available with expansion tank or hermetically sealed design
Power Transformers
Power transformers are high-capacity units designed to transfer and transform energy within medium- to high-voltage transmission systems. Their primary function is to adjust voltage levels in transmission networks, enabling efficient power distribution over large areas and supplying industrial users or distribution substations.
Technical Specifications
- Power ratings up to 120 MVA.
- Nominal voltages up to 132 kV.
- Copper windings.
- Compliance with IRAM, IEC, and ANSI standards.
Special Purpose Transformers and Custom Engineering.
We design special transformers tailored to the specific needs of each industry and client, including high altitudes, extreme temperatures, and confined spaces. This is made possible by in-house design and manufacturing in Argentina, supported by a team of expert engineers ensuring high-quality solutions.
Types of Special Transformers:
-
Oil & Gas:
Designed to withstand extreme conditions and the demanding requirements of the oil and gas sector, these transformers feature multiple taps and are suitable for operation with variable frequency drives, handling harmonics and DC components. -
Mining::
These transformers are built to withstand underground and outdoor environments with harsh conditions, including explosive atmospheres and climatic variations. -
Submersible (Well-Type):
Specifically designed for underground installations, these transformers are hermetically sealed, without an expansion tank, and are suitable for underwater operation. -
Custom Engineering:
We deliver tailor-made projects, meeting the most demanding requirements of each client.
Accessories and Protection Systems
We offer a complete range of accessories and protection systems to optimize the performance and safety of our transformers. These components are essential to ensure reliable operation and extend equipment lifespan under demanding conditions.
Available Accessories:
- Buchholz Relay.
- Thermometers (Dial and Stem Type).
- Winding Temperature Indicator (WTI).
- Zapatas y Bornes.
- Silica Gel Breather.
- Magnetic Oil Level Indicator.
- RIS (Rapid Internal Pressure Rise System).
- Terminal Box.
- Pressure Relief Valve.

Frequently Asked Questions about Oil-Immersed Solutions.
What advantages do oil-immersed transformers offer compared to dry-type ones?
How often should dielectric oil analysis be performed?
It is recommended to perform a physicochemical test annually to verify dielectric strength, moisture presence, and oxidation state, thereby ensuring the integrity of the internal insulation and extending the equipment's lifespan.
Do you comply with environmental safety regulations?
Yes, our equipment is designed under IRAM and IEC standards. Additionally, they can be configured to use biodegradable vegetable oils (natural esters) in areas with strict environmental requirements under ISO 14001 certification.
How is the oil level monitored in these transformers?
The level is monitored using visual or magnetic indicators placed on the expansion tank or on the main tank (in hermetically sealed transformers). This accessory allows for constant verification of the insulating liquid volume, which is essential for proper cooling.
What is the function of the air breather or silica gel dehydrating breather?
This accessory removes moisture from the air entering the transformer. It utilizes silica gel crystals that act as an indicator: the blue color signals they are dry, and the pink color indicates moisture saturation, warning that replacement is needed to protect the equipment's internal atmosphere.
With over 60 years of experience and ISO 9001, 14001, and 45001 certifications, we guarantee reliable and efficient products, complying with the highest safety and environmental standards.
