Medium Voltage Reactors For PFC
Medium Voltage Reactors (Detuned & Filter Solutions)
LTEC Medium Voltage (MV) Reactors are specially designed for power factor correction (PFC) and harmonic filtering systems. Used in series with capacitor banks, these reactors effectively prevent harmonic distortion and inrush current. Operating from 3kV to 35kV, they help extend capacitor life and ensure grid stability.
Core Advantages
Engineered for Grid Stability and Component Longevity
Optimized Economic Efficiency
Utilizing high-quality grain-oriented silicon steel sheets and a precision-tuned magnetic circuit, LTEC's medium-voltage reactors achieve superior linearity and extremely low core losses, saving you energy.
Military-Grade Insulation & Durability
Employing UL-certified Class H (180°C) resin with vacuum pressure impregnation (VPI) treatment, our medium-voltage reactors offer excellent moisture resistance, flame retardancy, and heat dissipation, helping you operate stably in harsh environments.
Elimination of Resonance Risks
Through the use of thin-layer insulation chips and advanced core design, the MV reactors effectively prevent system harmonic distortion, thus avoiding equipment failure due to dangerous resonant frequencies.
Zero-Maintenance Reliability
With a robust multi-layer air-gap core structure, the reactors ensure stable electromagnetic performance and constant inductance, helping you reduce the need for on-site inspections and maintenance.
High Overload Tolerance
Our medium-voltage reactors are all meticulously designed to not only have extremely strong impact resistance, but also withstand high harmonic content and switching surges without affecting linearity or safety.
Main Features
Precise Detuning Design
Offering standard blocking factors from 5% to 14%, LTEC MV reactors provide treatment for specific harmonics (3rd, 5th, and 7th).
Strict Linearity Control
Designed with a high linearity ratio (1.55–2.2In), our reactors ensure that the reactor maintains its inductance value even under severe current overloads.
Superior Material Build
Utilizing high-purity copper or aluminum windings and robust copper strip terminals, the reactors provide maximum conductivity.
Natural Air Cooling
An efficient heat dissipation design allows our reactors to operate stably without forced cooling, even in ambient temperatures ranging from -25°C to +50°C.
Global Standard Compliance
All our medium voltage reactors are designed to meet EN 60076-6 and UL 1446 technical requirements.

FAQ
Q: What is the primary function of an LTEC medium voltage reactor?
A: By shifting the resonant frequency of the power factor correction (PFC) system from the harmonic order, our MV reactors protect capacitor banks from harmonic overloads and prevent resonance.
Q: Why is Class H insulation important for MV reactors?
A: MV reactors generate a significant amount of heat during harmonic processing. Class H (180°C) resin provides the necessary thermal margin to prevent insulation breakdown.
Q: Can LTEC MV reactors be customized for high-altitude applications?
A: Sure. We can provide customized designs for MV reactors at altitudes up to 5000 meters, ensuring insulation gaps and cooling meet specific environmental and weather requirements.
