Compensating capacitors series k78-99 AP 2 are used to correct the power factor of electromagnetic throttles of gas-discharge lamps and transformers in electrical networks with a frequency of 50-60 Hz. They have high electrical strength, small size and weight with a large capacitor capacity, as well as a built-in over pressure fuse. They are made of self-aligning polypropylene film in aluminum housings with different variants of electrical terminals.
