EPCOS / TDK MKD AC Gas Capacitors
EPCOS / TDK MKD AC Gas Capacitors are three-phase gas-filled capacitors with a voltage range of 460VAC to 1415VAC. These capacitors feature self-healing properties and are filled with non-flammable nitrogen gas instead of the soft polyurethane resin used in the existing series. Matching the megatrend of the electrification of mobility and renewable energies, these capacitors suppress harmonic distortions, reducing reactive power at the input and/or the output of inverters. This improves the power quality and makes applications like wind, solar energy, and industrial drives more reliable.
EPCOS / TDK MKD capacitors offer diameters from 75mm to 136mm, heights from 218mm to 351mm, and a lifetime expectancy of 250,000 hours at +70°C at the hotspot. These capacitors feature winding construction based on a metalized polypropylene film and are equipped with overpressure disconnectors for all three phases, ensuring controlled disconnection in case of overload. Cage clamps with M4, M5, or M6 are used as terminals.
