Distribution substation ISET is a fully factory-ready free-standing or attached substation.
Depending on the customer's requirements, ISET distribution substation can be equipped with medium voltage switchgears with vacuum or gas-insulated circuit breakers, oil or dry transformers, low-voltage switchgear, which are manufactured by AIDI-ENGINEERING LLC.
The substation is equipped with all necessary auxiliary systems: heating, natural ventilation, lighting.
If necessary, the substation can have forced ventilation, air conditioning, security and fire alarm systems.
All equipment and engineering systems are installed at the site of manufacturer and do not require installation on site.
ISET substation provides metering of electric energy.
It is possible to remotely control the switches on the LV and HV sides (option).
Advantages:
- Short installation time
- Small dimensions.
- Customization.
- Safe maintenance
- Energy efficiency and adaptation to harsh climatic conditions
- Vandal-proof.
- Seismic withstand 9 points
- Service life of ISET substation is not less than 25 years.
