L1 and L2 series low voltage power capacitors - Nokian Capacitors

Capacitor elements made of metallized polypropylene film are self-healing and dry without impregnation liquid. Each capacitor element is individually protected with patented internal protection..

L1 and L2 design have:

- smaller dimensions
- lower losses
- easy cable termination
- internal discharge resistors
- cable termination for one or two outputs (L2)

Nokian Capacitors low voltage power capacitors are manufactured by using latest technology. Capacitor elements are made of metallized polypropylene film. Elements are self-healing and dry without impregnation liquid. Each element is individually protected and can be selectively circuit detached at the end of its life.

Heat treatment of the winding elements provides excellent electric parameters. Each wind is put into plastic casing and closed within thermosetting resin which provides perfect seal of the element. These elements are placed inside sheet casing and connected in such way so as they can be one or three phase supplied.

Nokian Capacitors ceased to connect capacitor elements with cables led to common cable clamps. Contacts of capacitor elements are connected with copper rails put into two rows…
Sheet casing is filled with inorganic, neutral, fireproof, nontoxic granulated substance - vermiculite which absorbs energy arising and extinguishes flame in case of element’s damage. Capacitors are also equipped with metal thermic separators effectively compensating heat dissipation. Nokian capacitors have low losses and are constructed to be light in weight. The low voltage power capacitors comply with most national and international standards.
