Product Description
Long-distance rural distribution lines and localized residential grids often suffer from severe voltage sags and high line impedance, which degrade the efficiency of agricultural pumps and household appliances. We engineered our highly reliable Single-Phase Shunt Capacitor to provide localized, point-of-use reactive power compensation directly at the single-phase load terminals. During a municipal rural electrification upgrade we supplied, the installation of our Single-Phase Shunt Capacitor units successfully restored the sagging terminal voltage from 195V back to a stable 228V, reducing distribution line losses and improving the motor startup efficiency of localized agricultural machinery.
We manufacture every Single-Phase Shunt Capacitor using an advanced, segmented metallized film pattern that automatically isolates micro-defects without causing complete component breakdown, ensuring exceptional safety. Our rugged steel outer casing is double-sealed and coated with anti-corrosion paint, making it perfect for installation in harsh, high-humidity outdoor distribution boxes. With a field-proven failure rate of less than 0.02% over a ten-year operational lifespan, our single-phase capacitors have become the trusted choice for state utilities and municipal engineering projects worldwide.

Applications
Rural Power Grids: Localized voltage support and reactive compensation along long-distance single-phase distribution lines.
Agricultural Pumping Stations: Improving power factor and torque for heavy single-phase irrigation pumps.
Residential Distribution Panels: Individual reactive compensation for high-power single-phase household loads.
Industrial Workshops: Dedicated compensation for single-phase welding machines and localized heating equipment.
Customization & Factory Strength
With a monthly production capacity of over 80,000 units, our factory is a leading supplier of low-voltage compensation components. We provide extensive customization options for the Single-Phase Shunt Capacitor, including custom mounting bracket dimensions, specialized high-durability lead-out cables, and custom voltage ratings up to 1000V. Every batch undergoes 100% routine testing, including terminal-to-case high-voltage insulation tests, to ensure compliance with the highest international quality standards.
Packaging & Shipping
Packaging: Each unit is wrapped in a thick, moisture-proof anti-static bag, housed in an individual protective carton, and secured inside robust plywood crates.
Shipping: Pallets are wrapped with UV-resistant stretch film and protected by heavy-duty corner boards to withstand harsh sea transport conditions.
FAQ
Q1: Can we use a Single-Phase Shunt Capacitor in a three-phase delta or star connection?
A1: Yes. You can connect three Single-Phase Shunt Capacitor units together to form a three-phase bank (connected either in Delta or Star configuration). This is highly useful when you need to create custom three-phase configurations or require asymmetrical phase compensation in a customized panel.
Q2: What safety protection does this capacitor have against internal pressure buildup?
A2: Our capacitors feature an internal overpressure disconnector. If an internal fault causes gas generation, the internal pressure will expand the top cover slightly upward. This expansion safely tears the internal connecting wires at a pre-calibrated weak point, disconnecting the capacitor from the grid before casing rupture can occur.
