We are Manufacturer, Supplier, Exporter of Water Cooled Capacitors, Medium Voltage, Medium Frequency Capacitors, MV Capacitor and our setup is situated in Sangli, Maharashtra, India.
Imported bi-axially oriented double side hazy Polypropylene film is used as dielectric and 99.9% pure Aluminium foil is used as conductor in making of capacitors.
Winding of the element is carried out on a modern semi-automatic winding machine, in a class 100 environment. With extended foil design, with edge and end folding of aluminium foil, over voltage stress at the edges of the buried foil area is avoided. This also improves Partial Discharge Inception Voltage Value.
To identify weak spots / pin holes in the Polypropylene film, each element is tested with DC voltage in dry pressed conditions. Numbers of elements are interconnected in series – parallel combination depending on kVAr and Voltage rating of the Capacitor, with the help of modern soldering process.
The dry pack is wrapped with several layers of high quality insulating paper before inserting it into a pre treated / degreased Aluminium Container and the Top lid is welded by semiautomatic Pulse TIG welding machine.
The Aluminium Sheet used for fabricating containers manufactured of a special alloy. All metal parts of copper and brass are silver brazed to ensure homogeneous joint.
Porcelain bushings of desired BIL are fitted on the lid ensuring leakproofness. The metal parts of terminals are manufactured from extruded brass. The water cooling pipe is of 99.99% pure of adequate thickness electrolytic grade annealed copper and pressure tested for leaks before fitting on the pack. Number of Taps equal / unequal outputs can be provided as per Customer’s requirement. On specific request of client, imported over pressure switches are also fitted on the Capacitors.
All the terminal connections are tightened with torque wrench. The capacitors are then loaded in a PLC controlled autoclave for uniform heating and drying under vacuum for adequate period. After confirming the quality of drying by precision online monitoring instruments, Capacitors are then impregnated under vacuum with highly purified and degassed Non-Toxic non PCB impregnant. The capacitors are then subjected to all routine tests in accordance to IEC-60110-1.
Each and every Capacitor is subjected to Routine tests in accordance to IEC 60110-1.
