Product Introduction
Delta Capacitor Bank - Professional Power Factor Correction Solutions
Product Introduction
Are you looking to optimize your power system efficiency and reduce energy costs? Our delta capacitor bank provides an advanced solution for reactive power compensation in medium and low voltage electrical systems. A delta capacitor bank is a specialized three-phase assembly where capacitor units are connected in a triangular configuration, delivering superior performance compared to traditional star connections. With line-to-line voltage applied across each capacitor unit, this configuration generates three times more reactive power than equivalent star-connected systems. This makes our delta capacitor bank the ideal choice for industrial facilities, commercial buildings, and distribution networks seeking maximum power factor correction efficiency.
Built by Xi'an Xidian Medium and Low Voltage Electric Co., Ltd., our capacitor banks represent cutting-edge technology in electrical power management. You'll benefit from our decades of expertise in medium and low voltage power distribution equipment.

Main Features and Advantages
Superior Power Density
Our systems deliver three times the reactive power output compared to star-connected alternatives using identical capacitance values. This means you get maximum compensation in minimum space.
Robust Fault Tolerance
The triangular connection design ensures continued operation even if one phase fails. Your system maintains partial compensation capability, providing operational reliability you can trust.
Advanced Thermal Management
Low-loss polypropylene film construction minimizes internal heating. The dissipation factor of ≤0.2 W/kVAR ensures long-term stability and extended service life.
Harmonic Compatibility
When paired with detuned reactors, our banks effectively handle harmonic-rich environments common in modern industrial applications with variable frequency drives.
Cost-Effective Solution
Higher power density means reduced material costs and smaller installation footprint, delivering exceptional value for your investment.
Practical Applications
Your facility can benefit from our technology across various industries:
Industrial Manufacturing: Steel plants, mining operations, and heavy machinery facilities use our systems to correct poor power factor caused by inductive loads.
Commercial Buildings: Shopping centers, office complexes, and hospitals implement our solutions to reduce utility demand charges and improve voltage stability.
Infrastructure Projects: Railways, metro systems, and airports rely on our equipment for consistent power quality and reduced transmission losses.
Oil & Petrochemical: Refineries and chemical plants utilize our systems to manage reactive power in hazardous environments.
Power Distribution: Utilities and grid operators deploy our technology for voltage support and system efficiency improvements.
How It Works
The delta connection applies full line-to-line voltage across each capacitor unit, maximizing reactive power generation according to the formula Q = V² × ωC. When your system experiences lagging power factor from inductive loads, the capacitor bank automatically injects leading reactive power to achieve optimal balance.
The intelligent control system continuously monitors your power factor and switches capacitor steps as needed. This dynamic response ensures you maintain optimal efficiency under varying load conditions while preventing over-compensation.

FAQ
Q: Why choose delta over star connection for my low voltage system?
A: For the same capacitance, delta connection delivers 300% of the reactive power compared to star connection, making it more cost-effective and compact for low voltage applications.
Q: How does the system handle harmonic distortion?
A: We recommend detuned versions equipped with series reactors (7% or 14%) to prevent harmonic resonance and protect against harmonic currents.
Q: What happens if one phase fails?
A: The triangular connection allows continued operation with partial compensation. Modern protection systems detect the failure and alert maintenance personnel.
Q: What's the expected lifespan?
A: Under normal operating conditions (temperature <35°C, voltage <1.1Un), our high-quality systems typically last 10-15 years with proper maintenance.
Q: Can your systems work in high-altitude locations?
A: Yes, our high-altitude products are specifically designed to meet requirements up to 4000m above sea level.
