Insulated jointing tools are essential hand tools used in the electrical and telecommunications industries for safely connecting and splicing electrical cables or conductors. These tools are designed to provide insulation and protection from electrical shock, ensuring that technicians can work on live or potentially live systems with minimal risk of injury.

Insulated jointing tools are particularly critical in high-voltage environments where electrical hazards are prevalent. The insulation on the tools helps protect workers from accidental contact with live wires, as well as improving their overall safety when working with electrical systems.

Designed to aid the separation of cores during jointing, these wedges are moulded in nylon to resist detrimental wear at the tip during normal use. The smooth surface of the material ensures minimal damage to the core insulation, and they have been designed to reduce the risk of displacement whilst located between the cable cores.Designed to aid the separation of cores during jointing, these wedges are moulded in nylon to resist detrimental wear at the tip during normal use.

  • Originally developed for stripping the lead sheath from pilc cables
  • Widespread application in the removal of the bedding compound from waveform cne cables without damage to the soft aluminium neutral earth wires
  • Special shaped blade to ensure clean cut without damage to the underlying insulation allowing sheath of live cables to be safely removed
  • 245mm Overall Length
  • 39mm Depth of Blade
  • When stripping lead sheath the blade is so shaped that normal care a clean cut be made with-out damage to the underlying insulation, allowing the sheath of live cables to be safely removed. The blade of the Hepnyf can easily be re-sharpened with a file.

The Sicame Belling-Tool has been developed to enable jointers to bell cable earth sheaths during live jointing, where avoiding damage to insulation and observance of safety procedures are of primary importance. The tool is suitable for use on lead and aluminium sheaths, although extra care is recommended when belling aluminium in order to avoid tearing.

  • Special shaped blade to ensure clean cut without damage to the underlying insulation allowing sheath of live cables to be safely removed
  • 196mm Overall Length
  • The fully insulated Mini-Hepnyf has been developed to compliment the standard Hepnyf and has a particular beneficial application in the stripping of lead sheath from small PILC service cables, and the removal of mastic bedding on all types of waveform cables
  • When stripping lead sheath the blade is so shaped that, with normal care, a clean cut can be made  without damage to the underlying insulation , allowing the sheath of live cables to be safely removed. 
  • The blade of the Mini-Hepnyf can easily be re-sharpened with a file

  • The primary application of the 'Hepsaw' is for the removal of re-enterable resin from LV or MV cable joints.
  • Nylon 6 (50% GF)
