Electrical Power Utility Locating

Know where to dig! The 3M™ Electronic Marker System (EMS)  helps save electric utilities time and money by enabling field crews to quickly pinpoint the location of underground electric facilities, including cable runs, splices, vaults, conduits and road crossings. 3M also offers wide product support and service for increased safety, performance and reliability. EMS markers used for underground electric cable location are color-coded to APWA standards for visual reference and power utilities have their own frequency, helping reduce the risk of accidentally locating and excavating other underground electric facilities. For power utilities, all underground electric cable markers are red in color.

3M EMS Power series can be used to locate: 
 

  • Service drops
  • Buried transformers and splices
  • Street lighting
  • Distribution loops
  • Conduit stubs
  • Service laterals
  • Manhole covers
  • Utility and road crossings
