Green T.HE transformers: certified quality with low environmental impact
High efficiency cast resin transformers, for high performance even in extreme environmental conditions.
Green T.HE transformers are built according to the EN 50708-2-1 standard and fully comply with the new eco-compatible design rules of regulation 2019/1783 of the European Commission. They guarantee a significant reduction in energy consumption, thus promoting significant economic savings and the reduction of CO2 emissions into the atmosphere.
Low partial discharges, high quality
Partial discharges are microscopic phenomena occurring inside insulating resin cavities are a factor in the speeding up of the ageing process of a transformer.
Therefore, it is important that the values of such currents are limited. A low value of partial discharges represents the index of some positive factors, such as:
- proper and solid design criteria
- quality raw materials
- precision and competence in all phases of the production process.
Green T.HE transformers reduce environmental impact to a minimum and comply with the following classes:
The transformer can be stored, transported and used even with maximum relative humidity of up to 95%. Upon request, it is possible to supply E4 transformers for more demanding environments.
The transformer can operate, be transported and stored at temperatures as low as -25°C.
The transformer is subject to the risk of fire and reduced inflammability is required.
Fire on the transformer must be extinguished within laid-down limits.
Furthermore, in standard configuration, Green T.HE transformers guarantee a seismic resistance up to 0.2g* (light earthquakes) and can be fixed to the ground, thus avoiding any possibility of overturning.
Upon request, transformers with resistance up to 0.5g (AG5) can be requested for installation in areas with greater seismic danger.
The completely renewed magnetic core with newly developed and high performance materials, contributes to the reduction of transformer size and weight, while ensuring higher energy efficiency.
The HV (high voltage) and LV (low voltage) terminals have been modified and built to facilitate the connection of the product on both windings.
The ventilation bars temporarily increase the rated power (under normal service conditions).
There are 9 enclosure sizes available, with the possibility to choose 2 types of ventilation grill for each one, IP31 and IP23. It is also possible to choose the transformer with the enclosure either assembled or disassembled, to be assembled on site.
