LV-HV Cable Crimping Tools


Cembre HT131-UC hydraulic cable crimping tool is self contained and will accept any accessory for performing the “Deep Stepped Indent” system of crimping on aluminium cables.

The tool is also manufactured to accept the semicircular slotted dies, common to most 130 kN tools. The HT131-UC is supplied as the cable crimping tool, case for storage and accessories and shoulder strap – ideal for use on overhead lines and other LV-HV cable jointing, splicing and terminating applications.

The HT131-UC is a robust tool with a 180 degree rotatable head for improved, easier installation and operator comfort enabling crimping in confined or restricted areas including LV-HV switchgear, substations and electrical panels –  two-speed hydraulic compression tool which accepts a wide variety of C-shaped die sets.

The double speed action enables a fast advancing speed for rapid approach of the dies to the connector and a slower more powerful speed for crimping.

The Cembre HT131-UC tool has a pressure releasing system that can be easily operated at any stage of the compression. The hydraulic crimp tool is supplied in a robust plastic case which is suitable for storage of the Crimp Tool and 14 sets of semi-circular slotted crimping dies.

Cembre HT131-UC crimping tool


  • Crimping Force: 130kN
  • Rated Operating Pressure: 700 bar (10,000 psi)
  • Dimensions: Length 488mm, Width with handles closed 149mm, Width with handles open 349mm

  • Oil: AGIP ARNICA 32 or SHELL TELLUS TX 32 / equivalent (Approved by Cembre)

Cembre crimping tools should be cleaned daily (or after use) with a clean cloth removing any residue in particular particles close to pivots and moveable parts. Every six months it is essential Cembre HT131-UCcheck the oil level in the reservoir. If necessary fill oil level to the top lip and remove any excess air from the reservoir.

For storage and protection the Cembre HT131-UC tool is supplied in a robust carrying case for storage of the crimping tool and up to 20 sets of die sets.

  • Dimensions 620x380x135mm/360x280x48mm

  • With the Cembre HT131-UC tool is in rest position operate as follows:
  • Select the appropriate die set for the connector
  • Insert the die set into the crimping tool head
  • Insert the conductor in the connector
  • Position the connector between the dies and ensure the correct location of the crimp

Die Advancement

  • Set the crimp tool on release position by rotating main handle; open the move- able handle
  • Rotate main handle to operating position
  • Operate moveable handle for lower die advancement; this first stage rapidly closes the dies to the connector


  • Continue operating the moveable handle -the tool will automatically change over to the high pressure stage; the ram will advance until the dies meet
  • It is recommended to continue pumping until the maximum pressure valve is activated and a “click” is heard

Dies re-opening

  • Rotate main handle to release position
  • Completely close handles of the Cembre HT131-UC tool and the die 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

Application Range

The tool HT131-UC is supplied with the AU130-C adaptor, which will accept the semi-circular slotted dies (common to Cembre 130 kN tooling) suitable for:

  • Indentation on copper conductors
  • Circular Compression on copper conductors.
  • Hexagonal compression on copper, aldrey or aluminium conductors.

With the upper adaptor AU130-… and lower adaptor AC130-P, the tool HT131-U or HT131-UC can accept:

  • Pre-rounding dies UP 130-…

(used for converting aluminium sectoral conductor to a compact, round section).

  • Containing dies (MV, MVC, MVM, MUA series) and the relevant Indentors PS130-…/E (to crimp connectors on aluminium cables using the deep indent crimping system).
