Our AnXon brand film capacitors use high-quality polypropylene film as the dielectric material, and the electrodes are made of high-purity aluminum foil. Each capacitor unit is composed of multiple capacitor elements, which can be configured in series or parallel, with or without internal fuses. All components are equipped with edge folding, elongated foil structure, and sturdy edge welding technology to significantly extend their service life. These devices are immersed in PCB free M/DBT oil, achieving stable operation with low heat generation in indoor and outdoor applications.

Voltage range U_N	1.05; 3.15; 6.6/√3; 6.3: 10.5/√3: 10.5: 11/√3: 11/2; 11: 12/√3: 12/2: 12: 21/√3 : 22/√3:24/√3kV
Var power Q_N	50; 100; 150; 200; 300; 334; 400; 417; 500Kvar (Other voltage levels and capacities can be specially ordered.)
Tangent of loss angle tanδ	At rated voltage and a temperature of 20°C, the tangent of the loss angle (tan δ) for all-film dielectric capacitors shall not exceed 0.0005.
Capacitance tolerance	The deviation of the measured capacitance from the rated value shall be within -5% to +5% of the rated value; for three-phase capacitors, the ratio of the maximum to the minimum capacitance measured between any two terminals shall not exceed 1.02.
Voltage resistance:	The inter-electrode of the capacitor should be able to withstand an AC voltage of 2.15 times or a DC voltage of 4.3 times the rated voltage for 10 seconds without breakdown or flashover;
Overvoltage	At 1.1 times the rated voltage, the duration should not exceed 12 hours per 24 hours; at 1.15 times the rated voltage, the duration should not exceed 30 minutes per 24 hours; at 1.2 times the rated voltage, the duration should not exceed 5 minutes; and at 1.3 times the rated voltage, the duration should not exceed 1 minute.
Overcurrent	The capacitor shall be capable of operating under a continuous overcurrent not exceeding 1.3 times the rated current, caused by fundamental overvoltage, harmonics, or a combination of both. For capacitors with an actual capacitance of up to 1.05 times the rated capacitance, the permissible continuous overcurrent is 1.37 times the rated current.

The capacitor consists of a case and a core. The case is made of thin steel plates sealed and welded together. The case is welded with a porcelain bushing for outgoing lines, and lifting lugs for installation are welded on both sides of the case wall, with a grounding bolt on one side. The capacitor core is made by stacking multiple components and insulating parts. The components are formed by winding and flattening two aluminum foils as plates with a film paper composite dielectric or a full film dielectric sandwiched in between. The components in the core are connected in a certain series or parallel manner to meet the requirements of different voltages and capacities. For capacitors with internal fuses, each component is connected in series with a fuse. When a component breaks down, the intact components connected in parallel to it discharge, causing the fuse to quickly melt and cut off the faulty component within milliseconds, allowing the capacitor to continue operating. Three-phase capacitors are connected in a star configuration. The liquid dielectric is used in the capacitor to impregnate the solid dielectric and fill the voids inside the capacitor. It has excellent electrical and physical properties and good compatibility with other materials in the capacitor.
