Screwable earth rod

Complete system for the installation of drilled earthing systems up to 99 m by means of core drilling according to the requirements of very low earthing resistances, e.g. 1–2 ohm in pipeline applications or wherever earth rods cannot be driven in. Earth electrode with M16 female and male thread as per the requirement of DIN EN 62561-2. With device for suspension over borehole.
  • Tested system as per DIN EN 62561-2
  • Variable earth electrode lengths of 3.0 m / 1.5 m & 0.5 m for optimum installation with drill crane
  • Time savings through quick connection and insertion technology
  • Comprehensive accessories for installation, sealing and connections; e.g. to decoupling device
