Line for high extra-high voltage cable production
Mixer SpA In 2021, Mixer SpA celebrated the 25 th anni- versary of its foundation: a milestone that it says was reached through the pursuit of in- novation and technological improvement, to conceive solutions for the cable industry. The company recently built a new logistics area, with more than 2,500m 2 dedicated to the storage of materials and products. Read the full story in the March issue
and heavy, and also has to meet certain requirements, such as a high resistance to lateral pressure – achieved by corrugation. Copper, aluminium and stainless steel tapes are preferred for the metal sheath. Rosendahl Nextrom expects the line to be of interest to any cable manufacturer that produces high or extra-high voltage cables and wishes to obtain key processes (forming, welding and extrusion) from one source, which contributes to all of
Rosendahl Nextrom’s RH-W is a metal tape forming and welding line for high voltage (HV) and extra-high voltage (EVH) cables. If used in tandem with a compacting unit and triple extruder group, it is able to produce Al structure HV and EHV cable. Improvements were recently made to the welding unit and system parameters. The RH-W metal tape forming and welding line includes a non-stop in-line process for forming and welding an HV/ EHV cable with a corrugated or smooth profile, including the monitoring of all system parameters. ‘Non-stop’ in this context refers to the welding. The welding electrodes alternate, if necessary. While one is welding, the other can be exchanged or maintained. The line does not have to be stopped and production continues without waiting. The line can sheathe HV and EHV cables with a welding tube diameter of up to 200mm. The production of such a cable is demanding, since the cable is large
the line processes being coordinated and optimised.
