Compensating capacitors series K78-99 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. They are made of self-healing polypropylene film in aluminum cases with different variants of electrical terminals.
