High Dielectric Strength: Utilize advanced insulating materials like mixed-dielectric films, high-purity ceramics (e.g., Class 1 and Class 2), or specialized paper to prevent internal breakdown and flashovers.
Low Dissipation Factor: Engineered for "low-loss" operation, ensuring that minimal energy is wasted as heat during rapid charge/discharge cycles.
Superior Voltage-Capacity Stability: Capable of maintaining capacitance and managing high impulse voltages and ripple currents without degrading.
Robust Thermal Performance: Exhibit low temperature coefficients, ensuring capacitance remains stable even when ambient temperatures fluctuate.
Specialized Terminations: Feature heavy-duty screw terminals, tab terminals, or oil-impregnated housings to withstand mechanical stress and prevent electrical arcing.
A high-voltage capacitor is mainly composed of an outlet ceramic sleeve, a capacity cell group and a casing.
The outer casing is sealed with a thin steel plate, and the outer porcelain sleeve is welded on the outer casing. The terminal block is led out from the outer porcelain sleeve. The capacity cell group (also called the core) in the outer casing is connected by several capacity components. Capacitor papers, composite film papers, or pure films are used as mediums in these capacity cells, and aluminum foils are used as polar plates.
In order to meet the requirements for voltage withstand of various voltage classes, the capacity cells can be connected in series or in parallel. The capacity cell group of a single three-phase capacitor is connected in a triangular shape inside the casing.
Materials
Mica
Mica capacitors offer excellent stability, high precision, and low power loss, making them ideal for high-frequency and high-power applications. They resist changes due to temperature variations and age well.
Film
Film capacitors are made from a thin plastic film, such as polypropylene or polyester, which provides good insulation and self-healing properties.
Paper
Paper capacitors use thin paper sheets as a dielectric material, often impregnated with oil to increase their voltage resistance. These components are typically used in older electronic systems for filtering and coupling applications.
