Industrial Capacitors

This capacitor is widely used in the filed of power electronics and has the function of isolating the direct current, filtering out the high-order harmonics on the bus side, absorbing and protecting IGBT spikes, damping, clamping and the like. This capacitor is widely applied to EMI,such as high frequency welding inventer,UPS,electric vehicles etc.

This capacitor is widely used in the filed of power electronics and has the function of isolating the direct current, filtering out the high-order harmonics on the bus side, absorbing and protecting IGBT spikes, damping, clamping and the like.Static frequency converter for modern variable speed transmisson, in which the switching function of semiconductor generates many parasitic singal, therefore,capactiors are needed to filter, eliminate ripples and harmonics in the circuit. The self-healing metallized film capacitor can be used as a direct current connection and harmonic filtering of an intermediate circuit, and can also be used as an embedding and absorbing capacitor in a contorl circuit.The raw material of the capacitor has undergone a special metallzation coating -zhebian square resistance. By carrying out a special vacuum evaporation process on oneside of the polypropylene base film, the thickness of the coating layer is different positions of the film.The ability of capacitor to handle large current can be greatly improved by increasing the plant degere at the connection lead.

The capacitor for power electronic are use of metal-based thin-film without a sense of style winding, special spray gold process, molded case, or Myra tape packaging, fire-retardant epoxy resin seal, copper bolts,copper nuts or inserts leads. metallized polypropylene structure;excellent electric property;self-healing property;long lifetime;DC-link capacitor;Used in DC-Link circuits,Can replace electrolyticcapacitor;Low ESR,high ripple current handling capabilities;Low lnductance;Self-healing property.

CBB61 capacitors are rectangular in shape and are called metallized polypropylene film capacitors. It is based on polypropylene film capacitor dielectric, plate is coated on the film on a very thin layer of conductive material, generally aluminum or galvanized aluminum, and then wound. The two ends of the wound core are sprayed with molten metal as capacitance leads, so the inductance of the capacitor is small. One of the biggest characteristics of it is self-healing property, it will not occur capacitor internal short circuit. Because when the internal medium of the capacitor is broken down, the large current at the breakdown point will volatilize the coating on the surface of the film, making the capacitor return to normal use.The CBB61 Ac Motor Capacitors use is very wide,for example, it is suitable for the frequency of 50Hz/60Hz ac single phase motor starting and operating power. In addition,it can also adjust the speed of the motor.

The CBB60 capacitor has a cylindrical aluminum case , riot gear and solder structure.The bottom of the capacitor can also be bolted and drawn out with flexible wires .The capacitor has small size, light weight and good self-healing. It adopts zinc-aluminum edge thickening evaporation process, so it has excellent electrical performance and high reliability. The unique sophisticated technology enables the capacitor to withstand large surges and high voltages.It is suitable for the frequency of 50Hz/60Hz ac single phase motor to start and run power. The shape of the motor capacitor is cylindrical,ABS or PBT  plastic enclosure. It has self-healing property,good stability and reliability.

The capacitor uses secure metallized film,unique flattening and welding process,advanced shock pressure and equalized current pressure design, which ensure the stability and precision of the capacity, low the inductance, greatly improve the resistance of high voltage and inrush current .It is used in DC-Link filter circuits which can replace electrolytic capacitor.The equivalent series resistance of it is low.In addition, it is able to withstand high ripple current.

The CBB65 Ac Motor Capacitor adopts zinc-aluminum edge thickened metallized polypropylene film as the electrode and the dielectric. It is tightly rolled by high speed winding machine, sealed by aluminum shell, and impregnated with refined castor oil at high temperature to keep it in a vacuum state. Therefore, the capacitor can be more stable, longer life.Whats more,it adopted the second generation of mechanical explosion-proof design, so the reliability is very higher. It is suitable for the frequency of 50Hz/60Hz ac single phase motor starting and operating power. Besides, it also suitable for high power lighting lamps and lanterns of power factor compensation.

The film is wound around a strong core with the metallized layer facing inward. After the film has been wrapped, there will put a paster on the margin. The specified external disk diameter can be achieved.In addition, the coils are separated by plastic foam to protect the electrodes.
