Tractor Switch Sub (GCN-10)

The GCN-10 is an in-line tractor switching sub for use with the Geochain^TM system. It is designed to sit directly below the wireline x-over unit and above the TAS in the Geochain^TM string.

The switching sub allows the six outer conductors to be combined downhole to minimise voltage drop when deploying a tractor at the bottom of a Geochain^TM string.  Dedicated high current wiring then routes the tractor power along the central line 7 conductor through the entire string.  The sub can be wired to failsafe into either tractor mode or Geochain^TM mode
