Are you ready for the energy future?

Siemens blue GIS supports your energy transition with switchgear that uses Clean Air instead of fluorinated gases as insulating medium. As F-gas-free technology, blue GIS helps you meet current regulatory requirements on fluorinated gases and contains no F-gases within the specified product range.

Get transparent with blue GIS

The Siemens EcoTech label provides environmental data for blue GIS products — covering material composition, recyclability, and lifecycle information per ISO 14021 — giving customers verified data for their own sustainability assessment.

Powering F-gas-free technology

Learn more about Siemens’ innovation: how simulations and cross-disciplinary engineering are crafting the F-gas-free blue GIS switchgear systems.

Support a circular economy

Our ecodesign approach for blue GIS MV switchgear uses recyclable materials — backed by our REACH declaration, Life Cycle Assessment, and EPD per ISO 14021.

Comply with regulations

We offer a REACH-compliant material declaration, a Life Cycle Assessment (LCA) and an Environmental Product Declaration (Type II) according to ISO 14021. In addition, a material impact analysis is part of our design thinking.

Maintenance-free switchgear

Siemens blue GIS products are designed for low-maintenance operation across their 40-year service life and use Clean Air as insulating medium.

Great performance – compact footprint

Great performance – compact footprint. Our F-gas-free blue GIS products maintain the same dimensions as our conventional gas-insulated switchgear, ensuring an equally compact footprint and optimal use of available space.

Say goodbye to F-gases

Clean Air used as an insulating medium is made of natural-origin gases and does not contain SF6 or any other F-gases, ensuring regulation-compliant blue GIS products.

Enjoy long lasting design

Under normal service conditions, the expected service life of blue GIS is at least 40 years — reducing the need for early replacement.

Power distribution — digitally optimized

Digitalization improves the security and efficiency of energy systems by providing greater transparency and control. Siemens blue GIS products support this with technologies for automation, protection, and monitoring.

Green investment building

Automation

Take automation and remote control to the next level with our SICAM portfolio, which caters to remote and automation applications in power transmission and distribution.

Protection and measurement

Our blue GIS portfolio offers excellent protection and measuring devices from the SIPROTEC and SICAM family.

Monitoring

Benefit from increased reliability through continuous condition monitoring of temperature, humidity, partial discharge, gas density, load flow, and the circuit-breaker.

IoT

With the scalable Xcelerator IoT SaaS solution, Electrification X, we address the key challenges of the energy transition in one fully integrated IoT Suite.
