8DN8 up to 145 kV
Gas-Insulated High-voltage Switchgear
Description
All requirements nowadays specified for modern and advanced switchgear in terms of performance and reliability are met by our type 8DN8 switchgear for rated voltages of up to 145 kV.
This switchgear design represents one of the most compact solutions available in this voltage range.
The 8DN8's
contribute to making this switchgear extremely economical
Since the levels of noise and field emission (EMC) are extremely low, it is possible to integrate this switchgear even in sensitive environments, residential quarters and city centers.
With these characteristics, our 8DN8 type switchgear meets all the requirements for environmentally compatible high-voltage switchgear.
