MPP TYPE POWER CAPACITORS - Super cap Power capacitors are the unique solution for the reactive power compensation. Super-cap power capacitors are manufactured using Tri-Layer, Zn -Alloy, Heavy Edge, Low Metalised film to provide better bonding of element and long life. Correct thickness of MPP Film is results into low loss of capacitance, more reliable and stable in performance. The tight wound element on most advance machine results into zero defect winding with maximum output. MPP Capacitor have Self Healing property, which results to avoid, illuminate permanent short circuit. MPP Power capacitors very useful to improve the power factor of the load & so to reduce the cable line losses & thus reduced the system line current & thus useful to connect the extra load with same demand KVA.

Some Unique Features

Self healing type costrction to eliminates permanent short circuit.

Tight , Tri- layer winding, low tan delta value.

Available in Aluminium cylindrical Can Type Construction.

MPP Capacitor with pressure interrupter design

Conformance to IS 13340 & 41.

Heavy Duty film construction to withstand high & Freaquent voltage spikes.

Available in 3/5/6/9/10/12.5/15/20/25 Kvar.

Wide operating voltage range.

Available for Various applications.

SIELENT FEATURES:-

OVER PRESSURE DISCONNECT :

All electrical equipments, products have a certain life, it also applies to power capacitor.

As the construction of polypropylene type capacitor is to produce a pronounced short circuit-the HRC fuses, MCBs alone doesnt sufficient for fast protection; so the all capacitors are internally constructed such a way that a disconnector operates when there is over pressure generation. A uncountable switching, break downs occurs , result into thermal or electric overload. These all action results into formation of gases, which results into rise in pressure inside capacitor casing.

The increase in pressure causes increase in length of curvature of the lid element wire. Expansion beyond certain limit will cause tear off the internal Fuse wire & disconnects the capacitor element from line voltage.
