High Light Low Noise Dry Type Reactor ，20kVar 400V 3 Phase Reactor ，Dry Reactor for Reactive Power Compensation

CKSG-20/0.4-7 20kVar 400V Three Phase Dry Type Reactor

Product Introduction

The CKSG-20/0.4-7 20 kVar Dry Type Reactor adopts oil-free dry-type insulation and is mainly used in low-voltage reactive power compensation cabinets, connected in series with anti-harmonic capacitors. In low-voltage power grids with many harmonic sources such as rectifiers and frequency converters, high-order harmonics threaten the safe operation of transformers and electrical equipment.

Connected in series with capacitors, this Dry Type Reactor effectively suppresses harmonics, improves voltage waveforms and boosts power factor. It also reduces switching inrush current and operating overvoltage, protects power capacitors and other equipment, and extends capacitor service life.

Product Features & Characteristics

The CKSG-20/0.4-7 Dry Type Reactor is engineered with the following features:

● Dry-Type Output Structure
The Dry Type Reactor supports three-phase and single-phase output with a stable, fully dry-type structure. This CKSG-20/0.4-7 is a Three Phase unit designed for continuous industrial duty.
● High-Efficiency Low-Loss Core
Made of high-permeability, low-loss silicon steel, the core delivers stable performance, high precision and low temperature rise during long-term operation.
● Excellent Winding Heat Dissipation
Compact and uniform winding layout ensures excellent heat dissipation, neat appearance and stable electrical characteristics.
● Uniform & Durable Air Gaps
Evenly distributed core air gaps with reliable lining materials keep the reactance stable and guarantee long-term reliable service.
● Low Noise & Robust Structure
Firmly assembled structure keeps operating noise low; the reactor is stable and durable even under continuous load.
● Reliable Insulation Strength
High insulation class, strong mechanical performance and crack-resistant behaviour at low temperatures ensure safe operation.
● Anti-Corrosion & Wide Adaptability
Anti-corrosion terminals and treated exposed parts enable stable operation in harsh industrial environments.
● Compact & Easy Installation
Small size and lightweight design save cabinet space and make installation simple and fast.
