Within DEEMSA’s technological innovations developed for the growing industry and especially for the ecological environment maintenance, is the dry type transformer encapsulated in epoxy resin which does not produce any pollutants. The manufacturing process and product assembly is vacuum performed to prevent parts of the windings exist in the air.
These transformers are manufactured in the voltage levels of 1.2 kV, 2.4 kV, 5.0 kV, 13.2 kV, 23 kV to 34.5 kV. It is possible to manufacture for use with nonlinear loads, ready for harmonics factors K15, K19 to K21.
They are used in refineries and oil pumping plants, where safety, quality and efficiency are paramount. They are also ideal for working in hospitals and power plants. Always meeting the high standards of quality, safety and efficiency.
Advantages
Cleaner and ecological transformer
Maintenance free and do not generate toxic waste.
Great to work on offshore oil drilling.
Above its 80% nominal voltage, our encapsulated transformer, is kept partial discharges free which gives long life.
Most efficient in their performance.
Face short circuit high levels.
Protected against lightning or high voltage waves.
Withstand extreme environments and aggressive such as marine and outdoor, supporting up to 34.5 kV voltages.
Face high levels of boost.
| Construction features |
Electrical characteristics |
Substation compact type, modular. |
Wide range of voltage regulation. |
| Cooled by ambient air or by forced ventilation. |
Can be Substation type either open or compact, indoor or outdoor NEMA 1 NEMA 3R. |
| They are easy to maintain compared to oil transformers, which require more hours for maintenance and cleaning. |
They are the most efficient and with fewer losses, which saves energy and therefore cost savings for our customers. |
| Government regulations are less strict because they do not pollute the environment. |
Excellent mechanical stress support for short circuit. |
| No need to strain to contain spills. |
They are self-protected against lightning by aparta-rayo system integrated into the transformer. |
|
Do not spread the fire, because the materials used in their manufacture are self-extinguishing. |
|
Withstand momentary overloads above the nominal capacity if necessary increment by production processes or project needs. |
| |
Because they are sealed in their windings, can withstand highly corrosive environments, saline and aggressive without damage. |
