In 2012, PCORE launched a patented test terminal design called the SET Terminal or Seismically Enhanced Test terminal. A SET-Terminal utilizes a fiberglass rod that has a polymer sheath extruded over it as the center insulator. The top and bottom castings are then crimped onto the center insulator. The SET-Terminal is aluminum for current ratings up to 3000A. For 4000A and 5000A applications, the PCORE SET-Terminal is silver plated copper. A SET Terminal has a cantilever strength of 2500 ft-lbs. For permanent loading 50 % of this rating should not be exceeded.
For 345kV applications (1) corona ring is added to the top of the test terminal. For 500kV applications (2) corona rings are added to the test terminal.
