Why Choose ZHIMING's Split Phase Low-Voltage Shunt Power Capacitor?
Designed for Three Phase Unbalance Load
ZHIMING's low-voltage shunt power capacitor handle unbalanced load conditions effectively. The split phase compensation approach addresses real-world power systems where loads rarely distribute evenly across all three phases.
Higher Compensation Accuracy
The sub compensate reactive power method delivers precise power factor correction. Each phase gets individual attention rather than treating all three phases as a single unit, resulting in more accurate compensation results.
Better Energy Saving Performance
Split phase input and cut capacitor technology maximizes energy efficiency. Users typically notice improved electricity savings compared to conventional three phase compensation methods in facilities with unbalanced loads.
Convenient Terminal Block Design
The neutral lead terminal block configuration simplifies installation and maintenance. Technicians can easily connect and disconnect low-voltage shunt power capacitors without complicated wiring procedures.
International Standard Compliance
All products meet IEC 60831-2014 requirements. This ensures reliable performance, safety, and compatibility with global power system specifications and quality expectations.
FAQ
What is split phase compensation technology?
Split phase compensation technology allows each phase to be individually controlled for reactive power correction. Instead of treating all three phases as one unit, this approach cuts and inputs capacitors separately per phase, achieving higher compensation accuracy for unbalanced load conditions.
What standard does ZHIMING's low-voltage shunt power capacitor comply with?
ZHIMING’s split phase low-voltage shunt power capacitor complies with IEC 60831-2014 international standard. This certification ensures the product meets global safety requirements, performance specifications, and quality expectations for power factor correction equipment.
What makes the terminal block design convenient?
The low-voltage shunt power capacitor features a neutral lead connected to a terminal block configuration. This design allows technicians to easily perform sub cut and input operations for each phase. Installation and maintenance become simpler without requiring complicated wiring procedures.
What applications benefit from split phase low-voltage shunt power capacitors?
Facilities with unbalanced three phase loads benefit most from this technology. Common applications include manufacturing plants, commercial buildings, and industrial facilities where load distribution varies significantly between phases throughout daily operations.
