This box-type shunt capacitor uses metallized polypropylene film as the core dielectric, connected in parallel in low voltage distribution systems.
It compensates reactive power generated by inductive loads such as motors, transformers and inverters, effectively raises system power factor, stabilizes grid voltage, and reduces transmission energy loss.
The self-healing function automatically isolates tiny breakdown points on the film to avoid short circuit failure; the built-in discharge resistor ensures safe voltage drop after power cut, improving operation and maintenance safety.
