A zone area building section which all
equipment requires the same level protection. Metallic parts are connected to
the equipotential bonding directly.
• Local equipotential bonding within the protection
zone.
Benefits the lightning protection zone concept
• Minimisation the surge voltage couplings into
other cable systems arresting the energy-rich,
dangerous lightning currents directly the building
