APP Single Layer Capacitors

We provide specialized APP Single Layer Capacitors from Pune, Maharashtra, India. These Capacitors utilize APP (All Polypropylene) film as the dielectric material, which is single-layered and interleaved with Aluminum Foil or a similar metallic electrode. The construction of APP Single Layer Capacitors is fundamentally different from Metallized Polypropylene (MPP) Capacitors; they are a non-self-healing type, similar to traditional NSH (Non Self Healing) Capacitors, but optimized with the superior electrical properties of Polypropylene Film. The use of APP (All Polypropylene) film grants these Capacitors exceptionally low dielectric losses, resulting in high efficiency and minimal internal temperature rise during operation. This characteristic is particularly beneficial in high-power applications where thermal management is critical.

Our APP Single Layer Capacitors are engineered for superior performance in various Power Factor Correction (PFC) and filtering applications, particularly in systems exposed to moderate to high levels of harmonics. The single layer design contributes to robust physical stability and a highly uniform electric field distribution across the dielectric, which enhances the Capacitor’s resistance to partial discharges. The elements are tightly wound and typically impregnated with a non-toxic, biodegradable, and non-PCB insulating fluid. This impregnation process replaces air voids, dramatically increasing the dielectric strength and facilitating effective heat transfer to the sturdy metal Enclosure, which is often constructed from materials like CRCA (Cold Rolled Close Annealed) Steel or SS (Stainless Steel). The hermetically sealed nature of the Enclosure ensures longevity and consistent performance by preventing the ingress of moisture and contaminants.

These Capacitors are a preferred choice for heavy-duty industrial applications, including those involving large Motor Loads, Welding Equipment, and Induction Furnaces, where the ability to handle high peak currents and continuous current loading is paramount. The robust internal structure and high-quality MOC (Material of Construction) ensure a long operational life and high reliability. The low dissipation factor of the APP (All Polypropylene) film minimizes energy wastage, directly translating into significant energy savings for the end-users. We strictly adhere to quality standards such as IS (Indian Standards) and IEC (International Electrotechnical Commission), conducting thorough testing, including temperature rise tests and over-voltage withstand tests, on all Capacitors before dispatch. We supply these as standalone Units or integrated into custom-engineered Capacitor Banks and Harmonic Filter Panels, incorporating all necessary Components like Discharge Resistors, Contactors, and protective Fuses as Spare Parts and Accessories.
