Non Self Healing Capacitors - NSH capacitors

We offer high-quality Non Self Healing Capacitors, commonly referred to as NSH Capacitors, operating from Pune, Maharashtra, India. These Capacitors are essential Components in various electrical and electronic circuits, offering high reliability and stability in specific applications. Unlike MPP (Metallized Polypropylene) film capacitors, which feature self-healing properties, our NSH Capacitors are constructed using traditional dielectric materials, primarily High Quality Paper or Polypropylene Film with Aluminum Foils as electrodes, which results in a robust and non-self-healing design. This design choice makes them particularly suitable for applications where transient faults or voltage spikes are less frequent, or where a controlled failure mode is preferred.

Our NSH Capacitors are meticulously designed for precise operation, especially in areas demanding high current handling and stable capacitance values over a long operational period. They are primarily used for Power Factor Correction (PFC) in both LT (Low Tension) and HT (High Tension) electrical systems. The dielectric material is often impregnated with a non-toxic, non-PCB insulating oil or compound, enhancing heat dissipation and extending the lifespan of the Capacitors. This impregnation process ensures maximum insulation resistance and resistance to partial discharges. The rigid construction typically involves a hermetically sealed metal Enclosure, often made from materials like SS (Stainless Steel) or MS (Mild Steel), to protect the internal elements from environmental factors like moisture and dust.

The core advantage of Non Self Healing Capacitors lies in their stability and ability to handle high voltage and current stresses without significant degradation in capacitance. They maintain a higher degree of capacitance stability compared to self-healing types when operating under fluctuating load conditions. They are extensively used in Tuned Filter Banks for harmonic mitigation, where precise capacitance values are critical to filter performance. Their robust design allows them to be successfully employed in heavy-duty industrial applications, including those involving large Induction Furnaces, Rolling Mills, and high-power Motor Drives. Each NSH Capacitor undergoes rigorous testing for dielectric strength, capacitance value, and insulation resistance to guarantee performance according to national and international standards like IS (Indian Standards) and IEC (International Electrotechnical Commission). We offer these Capacitors as individual Units or integrated into large, custom-built Capacitor Banks and Filter Panels, complete with necessary Accessories like Discharge Resistors and Fuses.
