Medium Voltage power
Medium Voltage power Supplier
Medium Voltage power
Medium Voltage power capacitors are designed and manufactured by using latest technology high quality material. These capacitors employ a technique where in the dielectric comprises several layers of polypropylene film impregnated with an non PCB liquid. The fluid is biodegradable in environment. Electrodes are made from thin aluminum foils
Medium Voltage Power Capacitors are designed to improve power factor and voltage stability in electrical systems operating between 1kV and 33kV. These capacitors compensate for inductive loads such as motors, transformers, and long cable runs in industrial plants, utilities, and substations. They are built to withstand demanding conditions and offer high reliability over a long operational life. Daga Switchgears & Electricals Pvt. Ltd. is a trusted name in supplying high-quality Medium Voltage Power across Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam.
