Line Reactor

The Line Reactor is a critical component for ensuring precise harmonic mitigation and voltage stabilization in both high and low voltage power systems. By being placed in series between the power source and sensitive equipment, it effectively regulates current flow and protects against voltage spikes, harmonics, and other electrical disturbances. With its rugged and compact design, the Line Reactor enhances power quality, ensuring smooth and stable operation in diverse industrial, commercial, and renewable energy applications. This reliable solution improves system efficiency, extends the lifespan of equipment, and helps maintain optimal performance, making it an essential choice for any setup requiring consistent, high-quality power management.

Product Components

Magnetic Core (Iron Core or Air-Core Structure)
Iron Core Type
Constructed from laminated silicon steel sheets, typically designed with air gaps to prevent magnetic saturation, making it suitable for low-frequency, high-current applications.
Air-Core Type
Lacks an iron core and relies solely on the inductance of the windings.
Offers excellent high-frequency performance, strong resistance to saturation, and larger physical size compared to iron-core designs.

Winding (Coil)
Material
Made of copper or aluminum conductors, designed in multi-layer tightly wound or segmented structures to ensure low losses and high current-carrying capacity.
Insulation
Wrapped with polyester film, Nomex paper, or epoxy resin impregnation to enhance thermal resistance (commonly rated at Class H insulation).

Insulating Support Structure
Framework or Support
Constructed from fiberglass-reinforced plastic (FRP) or ceramic materials, securing the windings and isolating them from the magnetic core (if present).
Interlayer Insulation Spacers
Prevents turn-to-turn short circuits and reduces high-frequency eddy current losses.

Cooling System
Natural Cooling
Heat dissipation occurs through air convection, with the surface designed with cooling fins or ventilation holes.
Forced Air Cooling
High-power models are equipped with fans to enhance heat dissipation efficiency.

Enclosure and Protection
Metal or Engineering Plastic Enclosure
Protection rating IP20–IP54, offering dust and moisture resistance (higher protection required for outdoor models).
Electromagnetic Shielding Layer
Some models incorporate an internal metal mesh or magnetic shielding cover to minimize electromagnetic interference (EMI).

Connection Terminals
Copper busbars or bolt terminals, allowing quick installation.
High-voltage models may include insulated bushings for added safety.

Monitoring and Protection (Optional)
Temperature sensors (e.g., PT100) and overload alarm contacts for real-time condition monitoring.
