- Product Introduction
Jinneng electric HV parallel power capacitor is specifically designed for 50Hz/60Hz AC power systems to provide reactive power compensation, delivering critical benefits for electrical networks:
● Power Factor Correction – Improves system efficiency by reducing phase difference between current and voltage
● Reactive Power Compensation – Minimizes transmission losses and voltage drops
● Voltage Stabilization – Maintains grid voltage quality under fluctuating loads
● Energy Optimization – Maximizes utilization of generation and distribution infrastructure
● Our capacitors specially designs for nonlinear load environments,it has self-healing dielectric technology for extended service life
This type widely use in electrical substations,industrial plants,renewable energy facilities.mining and heavy power consumption operations.
Use conditions
Ambient requirements:
Altitude: ≤1000m
Ambient Temperature:-40°C to +45°C (maximum)
Installation Site Conditions:no severe mechanical vibration,free from harmful gases, vapors,no conductive or explosive dust
Using note:
Ventilation:Capacitors must operate with adequate ventilation,prohibited in sealed or non-ventilated enclosures due to overheating risks
Wiring Requirements:All electrical connections must use flexible conductors to prevent mechanical stress
Safety Critical: Non-compliance with ventilation rules may cause overheating and reduce capacitor lifespan.
For high-altitude (>1000m) or extreme temperature adaptations, contact us engineering team for derating guidelines
