⚙️ Features / Differentiators

These models are distinguished by their coupling configuration (DR/SAH for 3400 kvar model, YY for 2500 kvar model) and their capacity to withstand high impulse voltages (up to 125 kV). Controlled discharge timing and safe reconnection intervals provide reliable operation in demanding industrial environments.
