| POWER FACTOR CORRECTION CAPACITORS TYPE LKT ( CYLINDRICAL ALUMINIUM CASE ) | |||||||||||||
| POWER FACTOR CORRECTION CAPACITORS IN CLINDRICAL ALUMINIIUM CASES | |||||||||||||
| Voltage Load Capacity | Frako Power Factor Correction Capacitor have a load capacity in accordance with EN 60831-1 and 2 as well as IEC 831-1 and 2. | ||||||||||||
| Application | FRAKO manufactures three series of Power Factor Correction Capacitors: Basic, Standard and Primium . We recommend Basic Capacitors for networks with Low Harmonic content and normal ambient temperature. Standard Capacitors asr recommended for networks with Higher harmonic levels and/or high ambient temperature. Premium Capacitors should be used for demanding networks (i.e. networks with very high harmonic levels and /or very high ambient temperature). | ||||||||||||
| Frako holds the management system certification ISO 9001 and the environmental management system ISO 140001 | |||||||||||||
| Mechanical | Cylindrical aluminium case, dielectric consisting of metallized polypropylene foil. Filled with a stabilized | ||||||||||||
| Construction | Dry type filled with a flame inhibiting, stabilized mineral filler The dielectric is self-healing. In case of a breakdown caused, for example, by voltage overload, the self-healing effect takes place.If the self-healing process does not operate (e.g. because of voltage, current or thermal overload) the cover plate, which is designed as an overload valve, is raised and ruptures the internal connecting wires to the coils, so that the capacitor is separated from the mains.o the coils, so that the capacitor is separated from the mains. | ||||||||||||
| Design | Cylindrical aluminium case with mounted stud M 12 x 12. Three-phase capacitors with integrated | ||||||||||||
| discharge resistors. With mounted connecting terminal in tension spring method. | |||||||||||||
| Power Loss | Approximately 0.05 % (0.5 Watt/kVAr) measured at the connecting terminal including discharge resistors. | ||||||||||||
| Approximately 0.02 % (0.2 Watt/kVAr) measured at the capacitor coils. | |||||||||||||

| Discharging | According to EN 60831, every power capacitor must have a discharge device which guarantees a discharge to 75 VAC within three minutes. FRAKO capacitors type LKT have integrated discharge resistors which guarantee a discharge 75 Volts within one minute.Attention: Before touching the capacitor, the terminals must be short-circuited and connected to the case . | ||||||||||||
| Life expectancy | The use of thoroughly tested material as well as careful processing ensures quality and a long life expectancy of the products. Frako produces its capacitors according to own specifications, wihich surpass by far the requirements of EN 60831-1/2. Quality tests following each single manufacturing step, verify an outstanding manufacturing quality. Combined with a unique capacitor manufacturing technology, Frako achieves a worldwire leading durability. | ||||||||||||
| Safety features |  FRAKO power capacitors offer the highest safety with an overload disconnector, which activates at internal overpressure, disconnects the capacitor from the mains network and thereby prevents capacitor destruction. FRAKO carries out type tests and regular random tests to monitor the production safety of this function. The test conditions comply to IEC 831 standards. FRAKO power capacitors offer, therefore, the highest possible standard of safety at overload and at theend of their life expectancy. |
