Cable Peeling Tool (Motorised)

Remove Bonded Semicon Screen & XLPE Insulation From Extra High Voltage Cables

Alroc AMF5 55-160 cable peeling tools are used by HV-EHV cable jointers for the removal of XLPE insulation and shaving of semi-conductive (bonded semi-con screen) on transmission and distribution cables from 132kV up to 400kV.

Alroc AMF5 55-160 tool can be used on HV-EHV cables with an outside diameter range of 55-160mm and is designed to make the removal of high voltage polymeric cable insulation (XLPE) simple and efficient with significantly reduced sanding required by the cable jointer using a lower grit abrasive.

The cable jointing tool provides XLPE insulation removal and lengthening of the cable chamfer on the transition to enable installation of cable joints, terminations or connectors.

Alroc AMF5 55-160 is a motorised HV-EHV underground cable peeling tool used in conjunction with the Alroc BMFD/50-160 tool when chamfering HV cables – the jointing tool will perform a cable chamfer but not pencilling of high voltage power cables.

Tools also available to remove bonded screens from 11kV/33kV cables with XLPE insulation.

• Diameter 55-160mm
• Bonded Semicon Thickness Capacity 3mm
• Remaining Length Of The Semicon 80mm

Here in the video the Alroc jointing tool is shown preparing and shaving the semicon screen on a 400kV 2500sqmm EHV cable with polymeric XLPE type insulation.

♦ Bonded Semiconductor Removal – the semicon screen is removed in a controlled and steady preparation (16 wheels rolling around the cable) effectively shaping the cable round over the XLPE insulation. A constant diameter over the XLPE insulation is achieved preventing the tool blade from digging or cutting into the insulation.

♦ XLPE Insulation Removal – the back-iron enables the cable jointer to set the pitch of the tool thus making the rotation of the cable tool easy when removing the high voltage XLPE cable insulation.

Image : Goodbye Glass. Jimmy Nicklin (HV EHV Jointer) – the Alroc AMF5 55-160 tool removes the need for HV jointers to “glass” the outer conductive sheaths as the highly precision engineered cable jointing tool provides accurate stripping of cables in a motor controlled rather than manual process.

XLPE Cables HVDC

The design and construction of the transmission grid of the future with overhead transmission lines and underground cable required to meet future demand of electricity supply has led to the development by ABB of XLPE DC cables rated higher than 500kV.

The EirGrid East-West Interconnector (EWIP) links the high-voltage power grids of Ireland and Great Britain by means of an HVDC Light interconnection. The interconnector enables Ireland to import and export power to and from Britain, thereby creating a more competitive home market and reducing consumer prices.

ABB were responsible for delivering the entire solution – including design, engineering, type testing, manufacture, civil works, cable pulling/laying, cable jointing, trenching, installation and commissioning. The video shows the loading of the high voltage cable for the project EirGrid East West Interconnector (EWIP) that took place in April 2012 in Karlskrona, Sweden.
