Since then ABB has introduced various new types of GCBs with increased func-tionality to the market – most recently type HEC 9 with the world’s highest short circuit current breaking capability at 250kA using SF 6 technology at a rated maximum voltage of 31.5 kV. HEC 9’s development is an upgrade of the design and development of the GCB ...

2023年7月18日 · Recently, ABB introduced another high-performing GCB for the HEC platform: Encompassing dec-ades of successful field experience, the HEC 10 is the successor to the HEC 7/8. The HEC 10 offers additional benefits such as improved switching capability, lower SF 6 volume and leakage rate, and extended lifetime - all in a smaller footprint.
