Single/Three-Phase Capacitor Series Reactor
Carrying AC current, the series reactor is an essential component of reactive power compensation systems. Connected in series with capacitors, it suppresses harmonics, limits inrush current and switching overvoltage, improves voltage waveform and power factor, and protects capacitors and other power equipment. High-inductance types with 5-7% or 13% reactance rates are available.

Key Features
High-Quality Core
Imported silicon steel core with uniformly segmented air gaps separated by epoxy plates keeps gap stability during long-term operation.
Low-Noise Core Bonding
Core end faces bonded with quality silicon steel adhesive reduce running noise and provide good moisture and dust resistance.
Epoxy Cast Coil
Vacuum-cast with Class F epoxy and glass cloth reinforcement, the coil offers excellent insulation, high mechanical strength, and resistance to high current and thermal shock without cracking.
Low Partial Discharge
The non-hygroscopic epoxy cast coil ensures low partial discharge and safe operation in harsh environments.
Anti-Vibration Design
Epoxy blocks and silicone rubber pads at both coil ends effectively reduce vibration during operation.
