Big Splice ultrasonic welding: Large pipe connections enable new applications
Making splices with ultrasound – basically welding cables together – is now pretty common for low-voltage stuff and cables with small cross-sections. But high-voltage applications with individual cable cross-sections from 16 to 95 mm² could also benefit from this tech. Various research projects and further developments are therefore currently underway.
Initial projects with cross-sections of up to 280 mm², known as big splices, have already been successful. This article high-lights the challenges along the way, possible solutions, the advantages that can be exploited and what will be possible in the future.
