Precision-engineered Components
Advanced Zero-Crossing Switching Technology
Complies with GB/T29312 Low-Voltage Reactive Power 

Compensation Switching Devices
Thyristor: Features a voltage withstand capability of ≥1800V, integrated with complete overvoltage protection circuits, voltage surge suppression circuits (VT), and inrush current suppression circuits (dv/dt) to protect the thyristor from damage. A dedicated 
A high-frequency pulse transformer with primary-secondary isolation is adopted for forced triggering of the thyristor, enabling rapid and deep conduction with high-power triggering.

Latching Relay: The high-power latching relay has a rated current of ≥100A and an inter-contact voltage withstand capability of ≥3000V;

Zero-Pressure Differential Closing: Achieves inrush-free switching-on and arc-free zero-current breaking. The mechanical and electrical service life of the switch reaches 1.2 million cycles (for on-load switching).

Integration: Integrates capacitors, reactors (if required), switching devices, protection functions, monitoring functions, communication modules, and controllers into a single module.
Intelligence: Automatically executes and completes functions such as monitoring, control, execution, protection, and communication; adapts independently according to the power quality of the distribution network and realizes automatic networking.
Equipped with complete protection functions against overvoltage, undervoltage, overcurrent, imbalance, harmonics, temperature, etc.
The power capacitor features a low-designed electric field strength, ensuring a long service life, stability, and reliability.
