English to Serbian Tech/Engineering Chemistry; Chem Sci/Eng Electrowinning tankhouse

Kontekst - elektrolitičke ćelije u postrojenju za elektrolitičku rafinaciju, ali ne znam kako se zova ova konstrukcija za nekakvo premošćavanje? Evo pojašnjenje o čemu se radi:

G Corner designs and manufactures a unique range of shorting frames, sometimes called Jumper frames, for electrowinning refineries of base metals such as Copper, Nickel and Zinc.
Shorting frames are used to allow the current flowing through the cell line to by-pass one or two cells, these cells can then be worked on for maintenance.
