Product introduction

The Aierway HB-12 is a next-generation, environmentally conscious gas insulated switchgear (GIS) designed for medium-voltage applications up to 12kV. It represents a significant advancement in switchgear technology by utilizing eco-friendly insulating gases as alternatives to traditional SF₆, aligning with global sustainability initiatives and stringent environmental regulations.

Key Features

1. Eco-Friendly Gas Technology
-SF₆-Free or Reduced-SF₆ Formulations:** Utilizes environmentally benign gas mixtures (such as clean air, N₂, CO₂, or fluoronitrile-based blends) with significantly lower Global Warming Potential (GWP).
– Minimal Environmental Impact:** GWP reduced by over 99% compared to pure SF₆, supporting carbon footprint reduction goals.
– Future-Proof Compliance:** Meets upcoming international regulations (EU F-Gas Regulation, EPA guidelines) restricting SF₆ usage.

2. Compact & Sealed Design
– Gas-Insulated Modules:** All live parts are enclosed in sealed, pressurized gas compartments, ensuring high reliability and safety.
– Space Optimization:** Compact footprint, ideal for space-constrained urban substations, high-rise buildings, and underground installations.
– Corrosion-Resistant Enclosure:** Powder-coated steel or stainless steel construction for durability in harsh environments.

3. Enhanced Safety & Reliability
-Fully Enclosed Design:** Eliminates risk of external contact with live parts, ensuring operator safety.
