Three Phase Dry Type Harmonic Filter Reactor 5kVar 400V With Natural Air Cooling

CKSG-5/0.4-7 5kVar 400V Three Phase Dry Type Reactor

Product Introduction

The CKSG-5/0.4-7 is a 5 kVar Dry Type Reactor developed for low-voltage capacitor compensation systems where harmonic control and equipment protection are required. Its oil-free dry-type insulation provides a compact and reliable solution for installation inside reactive power compensation cabinets.

When installed in series with power capacitors, the reactor forms an effective detuning and harmonic suppression circuit. It helps reduce the impact of harmonic currents generated by rectifiers, variable frequency drives, and other nonlinear loads, while improving voltage waveform stability and power factor performance.

The reactor also limits capacitor charging current during switching and helps reduce transient overvoltage. By minimizing electrical stress on compensation capacitors and related components, it contributes to more stable system operation and longer capacitor service life.

Product Features & Characteristics

Key Features of CKSG-5/0.4-7 Dry Type Reactor

● Oil-Free Dry-Type Design
The CKSG-5/0.4-7 uses a fully dry, oil-free construction and is available for both three-phase and single-phase applications. This model adopts a three-phase configuration for stable operation in industrial power systems.

● Low-Loss Magnetic Core
A high-permeability silicon steel core helps minimize magnetic losses and temperature rise, supporting consistent reactance and efficient operation during extended working cycles.

● Optimized Winding Construction
The windings are arranged with a compact and even structure to improve heat dissipation, maintain stable electrical characteristics, and enhance overall mechanical strength.

● Stable Air-Gap Configuration
Precisely distributed air gaps and durable insulating materials help maintain consistent inductance and reactance under continuous operating conditions.

● Quiet & Mechanically Stable
A reinforced assembly reduces vibration and operating noise while providing the structural strength required for continuous industrial service.

● Strong Insulation Performance
High-grade insulation materials provide reliable electrical isolation, mechanical strength, and resistance to cracking under low-temperature conditions.

● Corrosion-Resistant Components
Protected terminals and treated exposed metal surfaces improve resistance to corrosion, allowing the reactor to operate reliably in demanding industrial environments.

● Space-Saving Installation
The compact and lightweight construction reduces cabinet space requirements and simplifies mounting, wiring, and equipment integration.
