High Voltage Power Capacitors
General
Advanced Technology of KLV capacitors is based on construction of all-film capacitor sections, folding foil edge design, improved electrical and mechanical connections between sections and environmentally impregnation with compatible insulation oil KLV capacitor have very low dielectric losses and are designed for long service life.
KLV 3xxx
internally fused capacitors. each capacitor element has a separate internal fuse.
KLV1xxx
Capacitors without internal fuses
KLVxxx4
Single phase capacitors with two outputs (twin). Capacitors are supplied in set of three to provide an economical unbalanced detection scheme. This is particularly advantageous in low output capacitor banks.
