Real reviews from the field
The OPGW and ADSS cables supplied by SAS Smart Grid Networks performed exceptionally well during our grid expansion. Their fiber differential protection also significantly improved our fault response times.
Their distribution automation and relay protection systems enabled us to reduce outage durations by 40%. The integration with our SCADA was seamless.
The DAS system for transmission line monitoring has been flawless. We now detect vegetation encroachment and conductor vibrations in real time, avoiding costly failures.
