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.

Notes
* Dimensions with an asterisk (*) refer to internally fused capacitors
1) Voltage in parenthesis () refer to one-bushing capacitors only
2) For output and voltage outside this range, please contact factory.
3) Case sizes are typical and actual size will be confirmed at the time of order
4) Capacitor container could have 2 or 4 brackets (1 or 2 brackets on narrower side).
Dimension C-2 means 1 bracket from each side (capacitor type KLVxxx1); 4R means 2 brackets on each side, one on the top and one on the bottom only (type KLVxxx2).
5) Dim A may expand up to 115% due to thermal flexure.
6) Power at 60Hz = 1.2 x power at 50Hz
