Overview

SF₆-free High Voltage Switchgear

SF₆ (or Sulphur Hexafluoride) has been the industry standard gas used inside high-voltage electrical equipment as an insulating and arc-quenching medium. However, SF₆ is also listed as a potent greenhouse gas according to the Kyoto Protocol, with 24,300* times the comparative Global Warming Potential (GWP) of CO₂ and a lifetime of 1,000* years in the atmosphere. With a growing number of companies across the world becoming increasingly concerned about the environmental impact of their activities, we offer a commercially available and viable decarbonized alternative to SF₆ that helps utilities and industries reduce their carbon footprint.

INTRODUCING SF₆-FREE SWITCHGEAR PORTFOLIO

As part of the GRiDEA decarbonization product portfolio, our SF₆-free switchgear range features the same ratings and same dimensional footprint as the state-of-the-art SF₆ equipment, with a drastically reduced carbon footprint over the life cycle compared with SF₆ products and other alternatives. In addition, since product dimensions remaining the same, there is no increase in raw materials.

SF₆-free Range of Products

Let us move away from SF₆ no later than today. We launched our SF₆-free technology at CIGRE in Paris in 2014. Ten years later, a wide range of products up to 420 kV with reduced carbon footprint is already available. Check here to explore our SF₆-free product range to meet your new substation or substation extension project specifications and help you reach your net-zero objectives.
