Product Introduction

Air Core Current Limiting Reactor - Professional Power System Protection

Product Introduction

When your electrical system faces dangerous fault currents that threaten expensive switchgear and critical infrastructure, our Air Core Current Limiting Reactor provides the protection you need. This specialized static electrical device features a non-magnetic core design that introduces specific inductive impedance into your power system. Unlike traditional iron-core reactors, our air-core technology ensures linear inductance characteristics even under extreme fault conditions without magnetic saturation. Your circuit breakers, switchgear, and transformers gain essential protection from devastating short-circuit currents.

Main Features and Advantages

Linear Inductance Performance

Your reactor maintains constant inductance regardless of current magnitude. This prevents magnetic saturation during massive fault events.

Maintenance-Free Operation

No oil monitoring, leak repairs, or moving parts mean lower lifecycle costs for your facility.

Robust Mechanical Construction

Our winding structure withstands enormous electrodynamic forces during faults, often exceeding several tons.

Customizable Design

We adjust winding turns and layers during manufacturing to meet your precise grid impedance requirements.

Lightweight Solution

Significantly lighter than oil-immersed alternatives, reducing your foundation and installation costs.

Environmental Safety

Oil-free design eliminates fire hazards and soil contamination risks in your facility.

Practical Applications

Transmission and Distribution Substations

Install our reactors in series with outgoing feeders to limit fault currents. This allows you to use switchgear with lower short-circuit ratings while preventing total busbar blackouts.

Capacitor Bank Protection

Protect your high-voltage capacitor banks from damaging inrush currents during switching operations. Our Air Core Current Limiting Reactor prevents equipment damage and circuit breaker stress.

Industrial Facilities

Steel mills, refineries, and other heavy industries benefit from fault isolation on specific branches. This prevents voltage collapse on your main bus that could trip sensitive automation systems.

Bus-Tying Applications

Connect bus sections or parallel transformers safely. Normal conditions allow load sharing while faults trigger current limiting protection.

How It Works

Your reactor operates on simple yet effective principles. When installed in series with power lines, it introduces inductive reactance that limits current flow during fault conditions. The air-core design ensures linear response without saturation effects. During normal operation, the reactor presents minimal impedance. When faults occur, the increased reactance automatically limits current to safe levels your equipment can handle.

The epoxy-impregnated winding construction provides excellent mechanical strength and insulation properties. Natural air cooling maintains optimal operating temperatures without additional systems.
