Low Voltage APP
Low Voltage APP Supplier
Low Voltage APP
Low Voltage APP power capacitors are non self-healing type capacitors designed and manufactured by using latest technology and high quality material. These capacitors employ a technique where in the dielectric comprises of both sides rough, hazy polypropylene film impregnated with a non PCB liquid. The fluid is biodegradable in environment. Electrodes are made of high purity, thin aluminum foils.
Low Voltage APP Capacitors are designed for power factor correction in low-voltage electrical networks. “APP” stands for All Polypropylene, referring to the internal dielectric medium used for energy storage and insulation. These capacitors offer high reliability, low losses, and long service life, making them ideal for industrial and commercial power systems. Daga Switchgears & Electricals Pvt. Ltd. one of reputed Low Voltage APP Capacitors supplier in Kolkata, West Bengal, Odisha, Bihar, Jharkhand, Chhattisgarh, and Assam.
