China Dry Type Air-Core Series Reactor - Reliable Suppliers & Factory for Power Transmission Solutions

General
The Dry Type Air-Core Series Reactor is an essential electrical device utilized in power transmission and distribution systems across China. This high-performance reactor is specifically designed to limit fault currents, control power flow, and enhance power quality, making it a critical component for harmonic filters. As leading suppliers in the industry, our factory ensures that these reactors meet rigorous quality standards, providing reliable solutions for electrical systems worldwide.

    Structure
    The Dry Type Air-Core Series Reactor consists of multiple concentric cylindrical windings. These windings are connected in parallel using aluminum or copper conductors and are encapsulated with epoxy resin and fiberglass to form a robust structure. Ventilation channels are provided between the windings to facilitate natural convection for heat dissipation. The surface is coated with a protective layer to resist UV radiation and contamination.
    Advantage
    Coreless Design
    The dry-type air-core reactor does not have an iron core, eliminating the risk of magnetic saturation. This ensures good linearity of inductance, allowing the reactor to maintain stable reactance characteristics over a wide range of currents. It is particularly suitable for applications requiring high linearity.
    Oil-Free Structure
    The reactor is designed without oil, eliminating the risks of oil leakage and flammability. This design enhances operational safety and environmental friendliness, with no fire hazards.
    Excellent Heat Dissipation
    The reactor features a multi-layer parallel winding structure with air channels between the enclosures, facilitating natural air convection. This design ensures good heat dissipation and low hotspot temperatures.
    High Mechanical Strength
    The coil is encapsulated with epoxy resin and fiberglass, forming a robust structure after high-temperature curing. This high mechanical strength enables the reactor to withstand significant short-circuit current impacts.
    Low Losses
    The winding uses multiple strands of small-section conductors, reducing eddy current losses and stray magnetic losses. This results in low overall losses.
    Low Noise
    The reactor operates with low noise levels, making it suitable for noise-sensitive applications.
    Maintenance-Free
    The dry-type air-core reactor requires virtually no maintenance, with a long service life of up to 30 years.
    Flexible Installation
    The reactor is compact and lightweight, facilitating easy installation. It can be mounted vertically or horizontally and is suitable for both indoor and outdoor environments.
    Strong Environmental Adaptability
    The outer surface is coated with UV-resistant and anti-aging materials, allowing it to withstand harsh outdoor weather conditions over the long term.
    Economic Efficiency
    Compared to traditional oil-immersed or iron-core reactors, the dry-type air-core reactor has lower costs and reduced installation and maintenance expenses.
    These advantages make the dry-type air-core series reactor widely used in power systems.
    Frequently Asked Questions
