Malde Oil-Filled CapacitorsMalde Capacitors Mfg. Co. — since 1975
Oil-impregnatedNon-self-healing60-month guarantee30–50 yr lifeIS 135853–50 kVAr
Why choose Malde over other capacitors
- Built to last 30–50 yearsFilm + foil, non-self-healing “long working life” design — not a throw-away MPP can.
- 60-month guarantee — no fall in outputIf the capacitor current drops within 60 months, Malde replaces it or refunds the full price.
- Oil-impregnated & void-freeSAS-60 oil, wound in a Class-100 clean room, hermetically sealed and aged by heating & cooling.
- Made for Indian conditionsDesigned for our high ambient temperatures and voltage spikes; tolerates transients of reasonable amplitude.
- No kVAr loss from “self-healing”MPP capacitors lose a little metal (and kVAr) every time they self-heal. Film + foil does not.
- No internal corrosionThe element sits sealed in oil, so moisture cannot reach and corrode the electrodes.
- Thicker dielectric = more safety marginMore film thickness costs more to make, but stands up to spikes and heat for decades.
- Since 1975 · 1000+ satisfied clientsAutomobile, pharma, steel & rolling, textiles, hospitals, tiles & ceramics, tea estates, wind mills.

Oil-filled (Malde) vs dry MPP (self-healing)
| Malde oil-filled | Dry MPP | |
|---|---|---|
| Electrodes | Solid metal foil | Thin vapour-deposited metal layer |
| Dielectric | Thicker film, oil-impregnated | Thin film, dry / gas filled |
| On an internal fault | Element fuse isolates it | Self-heals — burns away metal |
| Output over years | No fall in current for 60 months (guaranteed) | kVAr drops gradually |
| Moisture & corrosion | Sealed in oil — protected | Metal layer can corrode |
| Heat & voltage spikes | Oil carries heat away, quenches discharges | More sensitive |
| Working life | 30–50 years (Malde) | Shorter |
| Price | Higher up front — more material | Lower up front |
Based on Malde Capacitors’ published notes and the general behaviour of the two technologies.
Keep your capacitor healthy
Measure the capacitor current with a tong tester or ammeter at least once every 2 months and keep a record. If the current falls, the capacitor is losing kVAr — with Malde, that is covered by the 60-month guarantee.
