Cembre HT-TC051

Thorne & Derrick International are Main UK Stockists and Suppliers of Cembre tools including crimping and cutting types for all constructions of LV MV HV cable including medium/high voltage 11kV/33kV power cables.

The following short article provides information about how to replace cutter blades (lower and upper) on the Cembre model HT-TC051 cutting tool – prolonged used of the tool can cause bluntening of the blades when cutting conductors, wires and cables.

For competitive prices, stock availability and technical advice about the Cembre HT-TC051 tool please do not hesitate to contact us.

Where hydraulic cable cutting tools loose their cutting edge it is recommended that the blades are replaced to enable the continuation of clean and efficient cutting.

In this case Thorne & Derrick and Cembre recommend proceeding as follows:

How To Replace Cutter Blades

Cembre Cable Cutting Tools

The following instructions should be read in conjunction with the image below.

Lower Cable Cutting Blade

Release latch (28) and open the cable cutter tool head

Operate moveable handle to advance the lower cutter blade (18) until holding screw (29) is visible on the ram (14)

Using a flat blade screwdriver remove the holding screw (29) and release the lower cutter blade (18)

Insert the new blade and fit the holding screw

♦ Warning: Before closing the cutter head release the oil pressure and retract the lower blade (18), otherwise the tool head assembly may hit and damage the lower cutting blade.

Upper Cable Cutting Blade

Release latch (28) and open the cable cutter tool head

Remove circlip (20 and extract the head pin (19) enough to release the cutting tool head assembly

Remove circlip (25) and pin (26) to release the latch (28)

Remove the latch spring from the upper cutter blade

Unscrew the 4 screws (21), remove the left hand guide (22), the right hand guide (24) and release the cutter blade (23)

Fit the left and right hand guides to the new cutter blade – place the spring into its seat and refit the latch

Fit the blade assembly to the head (13) fully insert the pin (19) and secure with the circlip (20)

Thorne & Derrick International are Main UK Stockists and Suppliers of Cembre tools including crimping and cutting types for all constructions of LV MV HV cable.

The following short article provides information about the general maintenance of the Cembre model HT-TC051 cutting tool.

Air in the hydraulic circuit may affect the performance of the hydraulic cable cutting tool e.g. no advancement or slow advancement of the lower cutting blade, lower blade pulsating.

For competitive prices, stock availability and technical advice about the Cembre HT-TC051 tool please do not hesitate to contact us.

In this case Thorne & Derrick and Cembre recommend proceeding as follows:

How To Purge Air Bubbles

From Hydraulic Circuit

Cembre Cable Cutting Tool

Hold cable cutting tool upright in a vice with handles open (Fig 1)
Unscrew main handle (03) from tool body (12) to expose the rubber oil reservoir (02)
Remove reservoir cap from the Cembre tool
Operate moveable handle several times in order to advance the ram
Press the pressure release handle (58) to retract the ram (14), discharge oil pressure from the circuit and return all oil to the reservoir
Repeat points (1-5) five times to ensure all air bubbles in the hydraulic circuit are purged into the reservoir of the tool
If the oil level is low, top up the oil level
Remove all air from reservoir (02) and fit cap (01)
Assemble the main handle (03) to cutting tool body

♦ Oil Top Up – every 6 months check the oil level in the reservoir. If necessary, top up the oil level to the top lip of the reservoir and remove all air from reservoi.

Always Use Clean Recommended Oil
Do Not Use Oil Or Recycled Oil
DO Not Use Hydraulic Brake Fluid

If the Cembre tool continues to malfunction and not cut cables safely or accurately return the hydraulic tool for service/repair.

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

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.

T&D stock Alroc cable jointing tools to enable the removal of outer cable sheath, XLPE insulation and semi-conductive screens (bonded and strippable).

Cable Stripping Tool

Remove LC Longitudinally Corrugated Copper Tape Shield From High Voltage Cables

Alroc PF3/06 cable jointing tools are used by cable jointers to remove the copper tape shield from MV-HV medium/high voltage power cables.

The video demonstrates removing LC shield without scoring into the semi-conductive screen layer below the copper tape shield – the Alroc PF3/06 cable jointers tool features grooved bushings so that the cable cutting blade sits on the highest point of the LC shield.

The scoring depth is set to .3 mm to guarantee reliable cutting without accidental screen cutting or deep scoring.

Safe for the cable. Safe for the hands.

Removing Bonded Semicon Screen 11kV 33kV Cables – Alroc CWB18-60

Alroc CWB18-60

Remove Bonded Semicon Screen From 11kV 33kV Power Cables

The new Alroc CWB/18-60-FEP cable jointers tool removes both the bonded semi-conducting screen without requiring lubrication while also creating a chamfer in a clean and reliable medium/high voltage cable preparation process – extensively used by jointers to prepare 11kV/33kV cables prior to the installation of MV HV Cold Shrink & Heat Shrink Joints and Terminations.

Contact T&D for Alroc tools and also a complete of cable jointing tools suitable for cable insulation removal and “easy-peel” screen stripping.

With a multitude of jointing tools available from several manufacturers, T&D decided to ask an industry expert in the jointing and terminating of MV, HV and EHV cables for an impartial and considered review of the new jointing tool manufactured by Alroc.

“Having used all types of jointing tools during my years this is by far the best and most consistent tool available. Alroc CWB/18-60-FEP has a working range of 18-60mm over the semi-conductive screen effectively covering 99% of all 11kV and 33kV MV HV power cables. The cable jointing tool design is based on rollers so no grease is needed for the cable peeling process.”

“The cutting blade can be used to chamfer the leading edge for pre-moulded HV cable terminations. Finally, the finish is another level” comments Karl McFadden (Cable Systems Application Engineer at Pfisterer).

The “Blue Tool” from Alroc creates a smooth finish to the insulation screen reducing sanding requirements by the jointer for bonded screen diameters up to 60mm. Operate using a consistent rhythm when turning the Alroc CWB/18-60 tool to achieve a smooth and clean finish without waves or “ghost-marks”.
