Single-phase dumping air coils AirECOdTM-7.2 kV

Purpose and design

AirECOd type single-phase air coils are designed for use in medium voltage reactive power compensation systems. The purpose of the coils is to limit the initial current that occurs in the circuit when the capacitive compensation stages are switched on. The elements are suitable for indoor use. Externally, the coils are protected with a leakage current-limiting paint to prevent contamination’s transition.
