A helicopter helped SMUD crews replace the insulators on their high voltage transmission lines above Elk Grove. The old insulators were installed in the early 1980’s, and it’s industry practice to replace them every 30 years.
These high voltage lines carry more than 230,000 volts of electricity. During the peak summer months, they transmit more than 400 megawatts, enough energy to power more than 300,000 homes. SMUD cut the power on these lines Wednesday morning so crews could work safely. No homes or businesses experienced any outages.
About two miles of lines were replaced Wednesday, another ten needs to be done by October 27.
