Windmills, substations, electro-transport, frequency converters, inverter of soldering, and etc.
The high voltage DC Link Capacitors are specifically designed for Windmills, substations, electro-transport, frequency converters, and other DC circuits. Because the Rectangular stainless steel casing is non-magnetic and is of the highest quality. The elements of these capacitors are made of metalized self-healing dry technology polypropylene film. And each element is sealed with high-performance flame-retardant epoxy resin. The special polymeric dielectric composition enables these capacitors to reach the maximum dielectric power in -40°C / +85°C temperature. These Qiyutech high voltage capacitors ensure matchless electrical characteristics together with small sizes. Additional specs include; 40 μF to 24000 μF Capacitance, long life span in harsh conditions, IEC61071, IEC 61881, and ±10％ (optional ±5％) capacitance tolerance.
Except for pre-listed capacitors, we are specialized in customizing capacitors, terminal styles, and stainless steel cases according to your requirements. And all capacitors of Qiyutech are RoHS compliant.
