ECOTRAFO-SP Dry-type transformers for special HV/LV distribution

Description

The TrafoELETTRO^® special electrical distribution range for the French market called ECOTRAFO-SP™ consists of around twenty standardised and normalised references up to 25 MVA for special electrical distribution applications in buildings.

 

The advantages of Trafo ELETTRO^® ‘s coated dry-type electrical transformers from the ECOTRAFO-SP™ range are mainly linked to the quality of the materials used and the factory know-how of our teams. Our TrafoELETTRO coated dry-type transformers are reputed to be among the most reliable on the market with an extremely low MTBF (Mean Time Between Failures).

 

To sum up, the ECOTRAFO-SP™ range of 20/0.41 kV encapsulated dry-type transformers is designed and manufactured along 3 axes of technical excellence for an optimum compromise between price and the proven technical design of the power distribution market.

 

TrafoELETTRO’s ECOTRAFO-SP™ HV/LV dry-type transformers are certified and compliant with the following classes:

• Environmental class E3:

Can be used in environments subject to heavy condensation (95% humidity) and heavy pollution. French national standard. On request, we can produce a class E4 “extremely polluted area”.

• Climatic class C2:

Suitable for operation, transport, and storage down to -25°C, ensuring the same level of performance even at low temperatures. French national standard. On request, we can produce C3 (Transport and storage at -40°C and operation at -50°C), C4 (The transformer is suitable for transport and storage at -50°C and operation at -40°C) or C5 (Transport and storage at -60°C and operation at -50°C).

• Fire behaviour class F1:

Self-extinguishing and low smoke emission in the event of fire, reduced risk of fire thanks to our resin’s low self-ignition properties.

 

Improved shock resistance:

Our transformers are designed, tested, and manufactured with a reinforced insulation class (improved shock resistance, BIL LIST 2), thanks to optimised insulation in sensitive areas of the device. We can quote for BIL1 on request.

 

Extended transformer life:

Thanks to the quality of the resin and the moulding and impregnation process, our transformers have a level of partial discharge on leaving the factory that exceeds the normative requirements of 10 Pc, with a measured level of less than 5 Pc.

 

Finally, the TrafoElettro^® ECOTRAFO-SP™ Range of special dry-type transformers is produced at standardised power ratings, so you benefit from the actual power mentioned without any power derating. In addition, the weight of our equipment is a good indicator of respected power and respected design and insulation safety coefficients.

 

This is why our TrafoELETTRO ECOTRAFO-SP™ electric transformers come with a 2-year warranty subject to the TrafoELETTRO special sales conditions.
