Screen Scoring Tools for High Votage Power Cables

Alroc screen stripping tools are used by high voltage cable jointers to strip non-bonded ("easy-strip") semi-conductive screens from 6.6kV, 11kV and 33kV high voltage power cables.

Alroc LHM1R leaves a semi-conductor strip length of 30 or 40mm.

Alroc LHM2R leaves a semi-conductor strip length of 30, 40, 45, 55 or 60mm.

High Voltage Cables, Semi-Conductive Screen Removal
Damage to the insulation during semi-conductive screen removal - this is probably the number one cause of all cable joint and cable termination failures. Care must be taken when cable jointers are removing the semi-conductive screen, any damage or nick to the cable insulation at this stage will result in creating an unscreened air void. Since the dielectric strength of air is less than that of the XLPE insulation, the concentration of electrical stress in this area will exceed the dielectric strength of air. The air will ionize causing corona discharge to occur. These discharges bombard the surrounding insulation 100 times a second, and will result in cutting through the insulation and ultimate high voltage power cable failure.

Alroc Cable Tools for power, telecommunications and fibre optics cable preparation. Alroc cable preparation tools enable the efficient dressing of cables by cable jointers including low voltage (LV, XLPE, PILC, EPR, PVC, waveform, consac) and high voltage (3.3kV, 6.6kV, 11kV, 33kV, Triplex up to 132kV) power cables - this covers the removal and stripping of outer cable sheaths, insulation, semi-conductor screens (bonded and "easy-strip" peelable) and lead cable sheaths prior to cable jointing or terminating with heat shrink, cold shrink or push on type cable joints and cable terminations.
