Project Description

Condensador bifásico de alta tensión

Single phase high voltage capacitors

Lifasa’s cos ϕ correction power capacitors and harmonic filtering for AT are manufactured under the stainless steel container/box base and porcelain terminals.

Single-phase (1 or 2 terminals) with internal fuses for connection to the mains via a double star. Recommended for voltage networks above 11 kV or need of high power equipment.
