LV-HV Cable Cutting Tools

HT-TC051

Cembre HT-TC051 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 50mm.

Cembre hydraulic cutting tools feature 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 90 degrees enabling the user to cut cables in the most comfortable position and can be opened easily to allow cutting of running cables.

The cutting blades of the Cembre HT-TC051 are manufactured from special high strength steel which is heat treated to ensure a long life in service.

The Cembre HT-TC051 cutting tool is fitted with a maximum hydraulic pressure valve.

With the cable on the lower blade, close the upper blade assembly and secure the latch
Before commencing the cutting operation ensure that the latch is fully secured: partial closure may damage the tool head

Blade Advancement

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 as and re-position the cable

Cable Cutting

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-TC051 – 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.
