Multifunction Tools

ALROC MF3/40

MF3/40 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 SR scoring stylus delivered with the tool), set the length to be removed and remove the insulation with a straight and neat cut.

The benefits of the Alroc MF3/40 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 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.
