Substation ISET is a fully factory-ready transformer substation with one, two or more power transformers. Transformers can be either oil or dry, with epoxy resin insulation.
The substation is equipped with all necessary auxiliary systems: heating, natural ventilation, lighting, socket network. If necessary, the substation can have forced ventilation, air conditioning, security and fire alarm systems.
Transformer substation ISET produced by AIDI-ENGINEERING has the following specific features:
Small dimensions.
ISET transformer substation has modular architecture and is supplied by blocks. Dimensions of each block allow its delivery by any type of transport.
Energy efficiency and adaptation to harsh climatic conditions.
Heat loss reduction is achieved through the use of mineral wool insulation and the installation of thermostats on heating devices.
Customization.
The modular design of ISET transformer substation allows to have flexible layout solutions. Dimensions of each block can also change according to customer requirements.
Vandal-proof
In the solid welded version, the block-modular building is manufactured with its own load-bearing frame. The wall material in this case is profiled steel sheet.
Short installation time
ISET transformer substations are supplied full factory ready with pre-installation check and adjustment of electrical equipment at the site of manufacturer.
Seismic withstand 9 points.
Service life of ISET transformer substation is not less than 25 years.
As a standard, the power supply to the transformer substations is made by cable, with a bottom entry. Connection to an overhead power line is also possible.
ISET transformer substation provides metering of electric energy. It is possible to remotely control the switches on the LV and HV sides (option).
