TMC Transformers has assembled a carefully selected group of engineers and technicians with vast experience in the design and manufacture of distribution transformers and special transformers, two different souls combined in a single body, offering customers the most suitable technology and service.

TMC focuses on dry type transformers and reactors for all applications worldwide. In South America in particular, TMC designs transformers for the mining sector, respecting the technical specifications and applicable standards.

Our dry-type transformers are considered a green technology that is fully environmentally compliant, non-polluting, and recyclable, which can be used in outdoor applications where oil-based solutions are typically employed.

Resistance to the harshest conditions

The mining sector requires highly reliable equipment to guarantee production, avoiding stoppages and profit losses. In addition, it the equipment must be maintenance-free and flexible in its use, as well as capable of withstanding extreme environmental conditions (dust, high and low temperatures, etc.).

These extreme environmental conditions in turn demand an electrically and mechanically robust equipment which is adequately protected against atmospheric agents.

TMC supplies equipment for the mining sector for various applications— VFD, distribution, and ventilation — with different types of protection cabinets for installation directly outdoors, in mining tunnels, or in pressurized electrical rooms. By installing our transformers outside, considerable energy savings can be obtained, avoiding to need air condition electrical rooms and thereby increasing the efficiency of the system.

TMC Transformers provides reliability and robustness for mining operations, reducing maintenance stoppages. With our vast experience in these applications, our engineering team is our key to being chosen in this sector and one of the main players in mining worldwide.

Successful cases:

TMC supplies dry type transformers for the El Teniente project. This Chilean region is home to the largest underground copper mine in the world, with 3000 km of underground tunnels and a yearly production of more than 22 million tons of copper.
