Corrugated copper shielding
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, under roof or ladder under roof, buried in ducts or directly buried.
