Heavy Duty Capacitors

Heavy Duty Capacitors are metallized polypropylene (MPP) capacitors. The capacitors come with stacked windings. The box capacitors are impregnated with a non-PCB biodegradable resin The cylindrical Capacitors are subjected to an extended period of drying after which the casing is filled with an inert gas to prevent corrosion of the winding elements and inner electrical contacts. Compact design ensures space saving.

Features of Heavy Duty Capacitors

• Range available: 1-30 kVAr (Cylindrical) & 1-50 kVAr (Box)
• Voltage: 440V, 480V & 525V
• Box (Resin-filled) & Cylindrical (Gas-filled) type construction
• MPP technology with Self-Healing & Over-pressure Disconnector
• Over current withstand capability  - 1.8 times of rated current
• Inrush current withstand capability  - 300 times of rated current
• Number of switching operations per year - 8000
• Improved operating life of capacitor - 150000 hours
• Low operating loss (0.35 W/kVAr)
• Application in commercial buildings with CFLs & SMPS, garment industries etc.

Heavy Duty Long Life Capacitors are used for loads exhibiting some amount of non-linearity, presence of harmonics, medium size industries.
