Capacitors

Capacitors are divided into two parts, two main capacitors and capacitors for industrial applications of electronic circuits

Capacitors for industrial applications
It is used with the machines, motors initiator or Assistant Manager to start the engines and to improve laboratory capacity for the components Kmassabih fluorescent or of the site as a whole and are usually the values ​​of an older Maikarovarad
Involved as these capacitors exposed to high hesitant efforts of 220 or higher and at more than one thousand volts, and often also passes through a large movement starting from 0.01 mA to a few hundred in case of power factor improvement

Therefore all be [mark = FFFF66] useless polar [/ mark], bear high efforts, solid mechanically, with high efficiency to minimize the heat produced, good ventilation and rates of heat transfer from the inside so as not to reach the degree of damage during operation with

For example, to improve the power factor for fluorescent lamp using normal capacitor Micro 2-4
As for improving the power factor Power Factor for a site a factory or the like, there is no intensive afford this amount of power, which may reach several hundreds of amps, so you use some types of motors which, when working without load appears as the Lamb of capacitive (condenser) on the line, choosing the motor power appropriate to the amp and then adjust the expected load (typically serve as a brake on the motor) can adjust the value of capacitance required

Old were made of insulating material and oil-impregnated paper was called capacitors and paper but now there are several types of the best.
