Abstract: An apparatus and method comprising an access tube which is insertable into a duct via a flange once an insulator of the ISO Bus system is removed. The access tube is configured so one end connects to the surface of the conductor and the second end remains open to the outside of the duct. The method comprises removing at least one insulator from the ISO Bus system and inserting the access tube through a flange and accessing the damaged conductor with one or more repair tools via an open end of the access tool. Any debris generated during the repair is contained in the access tube and can be easily vacuumed before removing the access tube.

Abstract: The present disclosure provides for an apparatus and method for repairing a damaged conductor of an ISO Bus system. The apparatus comprises an access tube which is insertable into a duct via a flange once an insulator of the ISO Bus system is removed. The access tube is configured so one end connects to the surface of the conductor and the second end remains open to the outside of the duct. The method comprises removing at least one insulator from the ISO Bus system and inserting the access tube through a flange and accessing the damaged conductor with one or more repair tools via an open end of the access tool. Any debris generated during the repair is contained in the access tube and can be easily vacuumed before removing the access tube providing a safe and efficient means for repairing conductors as compared to the prior art.
