HT-TC0851

Cembre HT-TC0851 hydraulic cable cutting tool is a hand operated tool designed for use by LV-HV cable jointers, overhead linesmen and electrical engineers for cutting copper, aluminium and telecommunication cables with a maximum overall cable diameter of 85mm.

Cembre hydraulic cutting tools are robust, self contained and sturdy featuring a double speed action a fast advancing speed for rapid approach of the blades to the cable and a slower more powerful speed for cutting.

The cutting tools are manufactured by Cembre from high strength steel and heat treated to ensure extended service life – the cable cutting tool head rotates through 180 degrees enabling the user to cut cables in the most comfortable position and can be opened easily to allow cutting of running cables.

The blades of the HT-TC0851 are manufactured from high strength special steel, heat treated to ensure a long service life.

The Cembre HT-TC0851 cutting tool is fitted with a maximum hydraulic pressure valve.

Instructions

Setting

  • With the tool is in rest position operate as follows:
  • Insert the conductor between the blades at the desired cutting point
  • For a running conductor, press latch and open the upper blade assembly
  • With the conductor on the lower blade close the upper blade assembly and secure the latch

Blade advancement

  • Rotate clockwise main handle, to release position thus releasing the moveable handle – Hold tool by both handles during the cutting operation.
  • Rotate main handle to operating position
  • Operate moveable handle for lower blade advancement. This first stage rapidly closes the lower blade to the conductor. Make sure that blades are exactly positioned on desired cutting point, otherwise re-open blades following instructions and position the conductor again

Cutting

  • Continue operating the moveable handle, the lower blade advances gradually until the conductor is fully cut

Blade retraction

  • Rotate main handle clockwise to release positionCembre HT-TC0851 Hydraulic Cable Cutting Tool
  • Completely close handles and the lower blade will retract

Rest setting

  • Completely retract the ram
  • Close handles and rotate main handle to rest position; the moveable handle will be locked
  • Store the tool in the plastic case

Blade replacement – See Figure 2 Below

  • After extended use, the blades may loose their cutting edge
  • Replace the blades as follows:

Lower blade:

  • Press latch (33) and open upper blade assembly (27).
  • Pump the moveable handle (59) to make the lower blade (25) advance until fixing pin (08) is visible on ram.
  • Remove fixing pin (87) and remove the lower blade (25).
  • Insert new blade and secure with fixing pin (87).

Warning: before closing the upperblade assembly, release the oil pressure and retract the lower blade, otherwise the blade may hit the lower blade edge and damage it.

3.6.2) Upper blade:

  • Press latch (33) and open upper blade assembly (27).
  • Remove circlip (93) and pivot (92).
  • By an hexagonal 13 mm, undo M8 nuts (94) and remove two studs (97), blade guide (95) blade spacer (96) and upper blade (27), noting the order of assembly.
  • Fitting the new blade is a reversal of the above.

Tool Maintenance Tips

Air in the hydraulic circuit of the cable cutting tool can affect use causing no advancement or slow advancement of the lower cutting blade or pulsating of the tool blade. To remedy this air bubbles must be purged from the hydraulic circuit exposing the rubber oil reservoir and operating the tool handle to advance the ram several times. Oil pressure can be discharged from the cutter tool circuit by pressing the pressure release lever to retract the ram.

It is recommended every six months to check the oil level in the reservoir of the Cembre HT-TC0851 – always use clean oil and not old/recycled oil or hydraulic brake fluid.

If in doubt, contact T&D to discuss the service, repair and supply of all Cembre cable cutting tools.
