Tape Tile & Stokbord Cable Protection Covers For MV HV Power Cables

Protect MV HV Cables – 11kV 33kV Cable Covers, Tiles & Tapes Using Tapetile & Stokbord

• Uploaded By Chris Dodds – Thorne & Derrick Sales & Marketing Manager

Why Use Cable Protection Covers?

Tape Tile & Stokbord

Centriforce Stokbord underground cable protection covers are manufactured from high impact, recycled polyethylene designed to withstand damage and protect medium/high voltage cables from plant and hand tools – the cable covers protect high voltage cables from damage caused by diggers and excavators inadvertently causing cable strikes when working around underground cables and utility services.

Both Tape Tile and Stokbord cable covers are used to protect LV-HV cables and cable ducts installed by the ‘open cut’ trench method – the cable protection products are intended, during any future excavation work, to give a clear visual warning of the presence of underground cable, cable joints or cable ducts. The cable identification is compliant with ENATS Standard 12-23 and meets the impact requirements of BS2484.

Pictured: High Voltage 11kV Cable Strike – an excavator has impacted onto a 11kV high voltage power cable penetrating the cable sheath and XLPE insulation to cause a power outage. Lack of planning on development projects increases the possibility of serious injuries to operatives and greatly increase cost to projects. On site cable records and use of cable fault locators should ensure worker safety and prevent accidental damage and strikes to high voltage cables.

Damage to underground cables can have serious repercussions such as damage to anyone working on or near the cables or a power blackout such as that experienced in Londonderry, December 2013.

LV Low Voltage | MV Medium Voltage | HV High Voltage Cable Protection

Why Use Stokbord? 

Centriforce Stokbord cable covers are suitable for underground high voltage cable protection (22kV, 33kV, 66kV, 132kV and up to 400kV). The 4 thickness variations of Stokbord covers are 6, 9, 12 and 18mm. This coupled with the fact that Stokbord is easy to fabricate ensures Centriforce Stokbords are the ideal product for protecting underground cables.

Stokbord Cable Cover Application

Centriforce Stokbord Cable Covers are fully jointed, laid overlapped and connected with plastic jointing pegs to provide safe high voltage underground cable protection.

Centriforce Stokbord cable covers feature a red background with yellow top tape containing visible warning “Caution Electric Cable Below” – Stokbord cable covers meet BS2482 impact requirements for underground cable cover protection.

Not only does this protect from any impact to the cables that would be made by excavation, it also shows exactly where cables are laid. The locating of cables is therefore simplified.

The features and benefits of Centriforce Stokbord makes the performance of the products far superior to steel and concrete cable covers / tiles /plates.

Stokbord Cable Covers – Benefits At A Glance

• Stokbord covers provide the clear warning to 3rd parties of underground buried cables
• Cable covers can be custom made with sizes to suit medium/high voltage cable trenches
• Contains bold warning text and company logo for clear MV-HV cable identification
• Damages to cables reduced – cost of repairs, HV jointing and supply disruption reduced
• Lightweight and easy to install Stokbord cable covers irrespective of weather conditions
• Durable with good impact resistance for MV HV EHV cable protection
• Rotproof and resistant to soil conditions for burial in underground cable trench

Cable Protection

Installation Of Cable Trench Covers & Cable Protection Tiles

All cables and ducts laid into cable trench should be over-protected by a cable protection cover or tape depending upon the highest voltage cable to be protected within the cable duct – typically in the UK the following cable protection tapes and covers are used for LV, MV and HV cables.

Marker tile tapes or Stokbord covers are installed over the cable in the appropriate trench drawings – usually there is no requirement to install either above approved cable ducts installed using trenchless techniques (i.e. directional drill) but either may be installed if it is deemed that additional MV-HV cable protection is required.

When Tape Tile is used it should be cut cleanly and installed so that the medium/high voltage cable is fully covered along the whole length of the installed cable duct.

Removing Outer Sheath HV EHV Cables – Alroc DMSR/80-160

Jointers Cable Tools | Low Medium High Voltage | LV MV HV 11kV 33kV 66kV 132kV

• Uploaded By Chris Dodds – Thorne & Derrick Sales & Marketing Manager

Cable Sheath Stripping Tool

Remove Outer Sheath & Jacket From High Voltage Cables

Alroc DMSR/80-160 cable jointing tools are used by jointers to remove the outer sheath and aluminium/lead shield from HV & EHV cables with outside diameters 80-160mm

Integral insulation screen detection is provided by successively performing a longitudinal and circular cut.

Alroc DMSR/80-160 cable jointing tool has an embedded mechanical dial gauge allowing the jointer to score the aluminium shield without cutting and causing cable damage.

The Alroc cable tool provides safe and precise cable cutting by the HV-EHV Jointer – a longitudinal cut ensures the cable screen is correctly scored without damaging the cable layer and setting up the thrust to prevent screen damage caused by the cable cutting blade.

The video demonstrates removing outer sheath from the EHV Extra High Voltage cable and the ability to switch from longitudinal cut to circular cut without removing the jointers tool from the cable.

A sound alerts when the tool blade is touching the aluminium/lead shield – the Alroc DMSR/80-160 cable jointers tool allows for very fine tuning and precision of the cutting depth, with a screen thickness capacity of 11mm / 0.433in and a diameter range of 80-160mm  / 3.150-6.299in.
