Ouality based on years of experienceWith more than 40 years of technical expeftise and over two millionoil-immersed transformers installed worldwide, we constantly designand improve the Minera transformer range to ensure optimumreliabillty and safety of your installations while offering the mostcost-effective solution. You are sure to invest in a proven technologyconstantly enhanced in our competence centers.

Our standard range of Minera transformers is available as:. Three phase units (single phase available on request). With ratings up to 20 MVA, 72.skV, 50/60 Nz

(Higher ratings available on request). Naturally cooled (ONAN) or air-forced (ONAfl upon request

We also offer transformers for special applications (rectifier, Oil & Gas Zone ll,earthing, welding,transformers with OLIC, reactors, etc.)

Minera oil-immersed transformers meet the requirements of internationalstandards such as ANSI, lEC, SPLN and individual country standards.

Minera, the right tunefor your network

Depending on the application andenvironmental influences, you might require adifferent type of oil-immersed transformer.Minera can deliver the flexibility you require:

. Breathing type with conservator, hermeticallysealed or nitrogen gas cushion sealed type

. For indoor applications: in buildings orindustrial plants, or in compact distributionsubstations

. For Outdoor applications: ground mountedbut also pad or pole mounted

. Low noise levels for urban or residentialareas

. Normal, low or very low level of losses toenhance the distribution network effrciency

. Vegetable Oil available on request

High quality levelfor more reliability

As a customer satisfaction is our main concern, we constantlyimprove our manufacturing processes, We have reduced our deliverytimes while ensuring a high quality level. All of our Mineraoil-immersed transformer production sites are ISO 9001 or ISO 14001and OHSAS 18001 certified.

To ensure this high level of quality, our Minera transformers undergoroutine tests in accordance with IEC standards. We can also proceedto type test or special tests on request.

Our company follows a policy of continuous improvement takinginto account the latest worldwide developments. This ensures thattransformers are state-of-the-art and comply fully with the moststrict requirements: fast delivery time, improved quality and recyclingcapabilities, reduced size and, on request, very low noise and verylow losses.
