Eco-efficient circuit-breakers help Danish island reduce

In keeping with its energy strategy, the island’s energy provider, Bornholms El-Net, chose ABB’s Live Tank circuit-breaker (LTA) with carbon dioxide (CO 2) to replace an aging Sulfr hexafluoride filled switchgear installation at Åkirkeby substation. When fully operational, the LTA technology will enable Bornholms El-Net to achieve an almost 100 percent reduction in global warming potential (GWP) as compared to gaz sf6 without any compromise on equipment quality and reliability.
