Clad series GF-F
Multiconductor Armour (Tape)
Corrugated copper shielding + Steel tape armour
Control, signalling, measuring and protective equipment, electric controls of high voltage substations (SSEE), its shielding allows adequate filtering of electromagnetic interference at frequencies up to 1 MHz. Installed in aerial trays, gutters or conduits, buried in ducts or directly buried. It has additional mechanical protection.
