Sustainability through SF6 reduction on HV/E-HV cable accessories

Abstract

The urgency to act on climate change has never been greater, and, in the absence of global regulation, companies are voluntarily stepping up to fill the gap. In the power cables industry, high focus is currently on the accessories, because of their extensive use of SF6 gas, as part of the equipment to carry out routine tests of joints and cable drums, and through their interface to the gas-insulated electrical equipment. The technical challenges connected to the SF6 reduction in the cable accessories are hereby presented, with the main R&D activities consequently generated.
