FAQ

What are the key features of ABB’s medium voltage switchgear products?

ABB‘s primary medium voltage switchgear products are designed to connect and protect the evolving grid. They feature robust construction, advanced safety mechanisms, high reliability, and ease of maintenance. They are designed to handle high electrical loads and provide efficient power distribution with minimal losses.

What standards and certifications that ABB’s medium voltage switchgear products comply with?

Our medium voltage switchgear products comply with international standards such as IEC and GB/DL. They are also certified by leading industry bodies to ensure the highest levels of safety and performance. ABB also offers medium voltage switchgear products for ANSI standards.

What support and services does ABB provide for installation, commissioning, and after-sales maintenance?

ABB provides comprehensive support services including installation, commissioning, and after-sales maintenance. Our team of experts ensures smooth deployment and ongoing support to maximize the performance and longevity of our switchgear products.

What are the insulation mediums that ABB offers in gas-insulated switchgear?

ABB offers two main insulation mediums in our gas-insulated switchgear portfolio:

SF6-free suitable for most 6kV to 24kV switching applications, with dry air as the insulation medium and a global warming potential (GWP) = 0. It is fully compliant with the IEC standards and the EU F-gas regulation (EU) 2024/573. Our SF6-free solutions are designed with similar interface, footprint, and operations as the original SF6 versions.
SF6 gas (Sulfur hexafluoride) as insulation medium.

ABB’s complete transition to SF6-free switchgear will be phased in line with our ambitious sustainability targets, evolving regulatory deadlines, market demand, and production capacity. However, this is a long-term strategy, and in the mid-term, we will continue offering both SF6 and SF6-free switchgear as required by our customer needs and market regulations.

What smart solutions are available for ABB’s GIS portfolio?

ABB’s switchgear smart solutions are designed to help our customers make data-driven decisions. Our customers can benefit from a wide range monitoring, diagnostic, automation and control features for their ABB’s gas-insulated medium voltage switchgear. Contact our sales team to learn more about ABB’s smart solutions for each of our switchgear.

What’s the difference in the circuit breaker for air-insulated vs gas-insulated?

In air-insulated switchgear the circuit breaker is typically withdrawable.
In gas-insulated switchgear it is fixed mounted. The function of withdraw is provided by a separate disconnecting switch. Typically, a three-position switch with connected, disconnected, and ready-to-earth position. Both circuit breakers are typically based on proven vacuum technology.

What are the maintenance requirements associated with the air-insulated switchgear (AIS) vs gas-insulated (GIS)?

Gas-insulated switchgear requires very low maintenance as all high voltage parts are permanently protected in a gas tank from soiling, humidity, entry of foreign bodies and other environmental influences. Primary, the drives located outside gas compartment require inspection and maintenance. On the other hand, gas-insulated switchgear repair requires additional training (e.g. for gas works) and the replacement of parts may not be as easily. In the air-insulated switchgear visual inspection is recommended in regular intervals, maintenance of power parts is given in installation, operation and maintenance manual (Click here for the manual 1VLM000363)
