Summary
Grid reliability depends on eliminating vulnerabilities before they become outages. One of the most overlooked risks is improperly sealed cable and conduit penetrations. Join this webinar to learn how preventing water, moisture, combustible gases, and rodent intrusion can improve system reliability, reduce unplanned outages, and protect critical utility assets. We'll also review electrical code requirements and best practices for sealing cable entrances in vaults, manholes, substations, service entrances, e-houses, and powerhouses.
