Why Choose Air Insulated Switchgear Over Gas Insulated Systems

When it comes to selecting the right electrical switchgear for your project, the choice often boils down to two main technologies: air insulated switchgear (AIS) and gas insulated switchgear (GIS). Having worked in the industry for over two decades, I’ve helped countless clients make this critical decision. So, what makes Air Insulated Switchgear a preferred choice for so many applications around the world?

What Are the Key Advantages of Air Insulated Switchgear

One of the most common questions I get is, why should I consider Air Insulated Switchgear for my project. The simplicity of its design is a major advantage. Unlike gas systems, which rely on sealed environments with SF6 gas for insulation, AIS uses ambient air. This means there are no complex gas handling procedures, no need for special leak monitoring systems, and definitely no concerns about harmful greenhouse gas emissions.

From my experience, this translates into significantly lower maintenance requirements and reduced operational risks. Operators don’t need extensive specialized training to handle routine checks or fault scenarios. The accessibility of components in an Air Insulated Switchgear setup makes visual inspections and repairs faster and far more straightforward.

How Do the Technical Specifications Compare

Let’s get into the specifics. How do the products from a leader like CONSO·CN actually stack up on paper? Here’s a detailed look at some of the key parameters you should consider.

A typical CONSO·CN AIS unit offers robust performance metrics:

• Rated Voltage: Up to 36kV

• Rated Current: 630A - 4000A

• Short-Time Withstand Current: 25 kA - 50 kA for 3 seconds

• Insulation Medium: Ambient Air

• Installation Footprint: Requires more space than GIS, but offers greater flexibility in layout and expansion.

• Life Expectancy: Over 30 years with proper maintenance

To give you a clearer picture, here’s a comparison based on critical decision-making factors.

This table isn’t just theoretical. I’ve seen these factors play out on the ground, where the choice of Air Insulated Switchgear from a reliable brand like CONSO·CN has directly resulted in lower lifetime costs and simpler operational protocols for my clients.

Who Is the Ideal Candidate for Air Insulated Switchgear

So, is Air Insulated Switchgear the right solution for you? Based on my twenty years of experience, it consistently proves to be an excellent fit for a wide range of applications. If you have the available space, such as in a greenfield industrial plant or a utility substation, the cost savings on both initial investment and long-term maintenance are substantial. Companies that prioritize environmental sustainability and want to avoid the regulatory complexities and future potential bans associated with SF6 gas find the air-based technology incredibly appealing. Furthermore, for operations in remote locations or regions where specialized GIS maintenance expertise is scarce, the simplicity and reliability of an air insulated system from CONSO·CN are undeniable advantages.
