Multifunction Tools

ALROC MF3/40-C

MF3/40-C multifunction cable tools are manufactured by Alroc and used by MV-HV jointers to remove the outer sheath (PE-PVC-PR) with a straight and neat cut, score the peelable semiconductor with a chamfer on the edge of the semiconductor cutback (with the SRC scoring stylus delivered with the tool), set the length to be removed and remove the insulation.

The benefits of the Alroc MF3/40-C Cable Jointing & Preparation Tool include tuning of the pitch of the tool and embedded wear pads to protect the tool from the contact with the outer sheath of the medium/high voltage cable. The Alroc MF3/40-C multifunction tool is available with one of the following scoring stylus options;

  • SRC – Scoring stylus for peelable semiconductor with chamfer,
  • SCH – Chamfering stylus for insulation,
  • SR – Scoring stylus for peelable semiconductor.
