Here the Jointer, Steffan Evans, from HVSM is shown expertly removing the cable sheath and bonded aluminium screen using the Ripley US15 Cable Sheath Stripping Tool (10-50mm) – the Jointing tool when used by Trained & Competent Jointers effortlessly and safely removes both the outer sheath jacket with aluminium foil screen without incurring damage to the copper wire screens on a 33kV single core 800sqmm XLPE insulated cable.

Cable Preparation | Excerpt from Nexans Euromold Type C Interface Connectors (K), (M), (P) 800PB/G Up to 20.8/36 (42)kV | Note the instruction references the requirement to remove the outer cable sheath with Aluminium foil together.

Caution: in the case of conductive coated outer cable sheaths, the conductive coating must be removed during the installation of accessories in order to be able to carry out e.g. cable sheath testing. For this purpose, the conductive coating of the outer cable sheath must be removed with a suitable stripping tool for a length of approx. 400 mm below the end of the cable sheath.

Stripping Bonded Screens 33kV

Here Steffan is shownly stripping bonded semi-conductor screen from medium voltage power cables (20/22kV) prior to terminating the cable into Siemens NXAIR type Vacuum Circuit Breaker – the Ripley US02-7000 comfortably caters for the precision stripping of the bonded screen from the 400sqmm cable for preparation of the Raychem (Tyco) heat shrink termination to be installed.

The US02 Tool manufactured by Ripley Tools features a revolving ergonomic handle and accessible adjustment knobs for comfort and ease-of-use, reducing effort and potential strain for cable jointers performing repetitive shaving functions in the field.

“Investing in innovation and introducing cable jointing tools to HVSM improves safety and reliability for our clients. The Ripley US02 is very Jointer-friendly with a spectacular finish to the XLPE insulation – the automatic cut-off and incremental blade adjustments ensure a professional perfection of cable preparation at medium voltages,” comments Steffan.
