Earthing terminals, used for static electricity earthing, are available in a standard length of 1.8m and are made from a solid steel core overlaid with copper cladding and a heavy bronze cap. Type AET electrodes provide the earthing of airport tarmac areas where any generation of static electricity could be hazardous, e.g. aircraft refuelling, servicing and cargo loading areas. The heavy duty capping has a ribbed design affording a fast and positive earthing connection by means of earth lead connector clips.
Earthing bonds are used in commercial earthing installations. The system provides an earth connection welded to the steel reinforcement, thus offering a virtually indestructible, stable and low resistance path to earth.
