Cembre HT131-C Crimping Tool (up to 400sqmm cables)
LV-HV Cable Crimping Tools
Cembre HT131-C crimping tool is lightweight and ideal for use on overhead lines and other LV-HV cable jointing, splicing and terminating applications. The hydraulic crimping tool features spring loaded handles allowing the Cembre die sets to be advanced with one hand – the other hand free to position the electrical connector prior to crimping.
In addition, the crimp tool head is fully rotatable through 180 degrees for ease of use and comfort for the user enabling crimping in confined or restricted areas including LV-HV switchgear, substations and electrical panels. The built in safety valve also by-pass the oil supply when maximum pressure has been reached – a pressure releasing system being easily operated at any stage of the compression process.
Cembre HT131-C hydraulic crimping tool is modified to accept die sets to perform “Deep Stepped Indent” system of crimping on aluminium cables.
Cembre HT131-C tool is suitable for compression of electrical connectors on conductors up to 400sqmm (800 MCM) and has three operating positions identified on the main handle.
The two-speed ram advance of the HT131-C allows for easy positioning of the connector, prior to the crimping process.
Cembre HT131-C crimping tool

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 check 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-C tool is supplied in a robust carrying case for storage of the crimping tool and up to 14 sets of die sets.
- Dimensions 620x380x135mm

Cembre HT131-C Hydraulic Crimping Tools
- With the Cembre HT131-C tool is in rest position operate as follows:
- Select the appropriate die set for the connector.
- Insert the die in the upper seat of the tool head until it is locked by die/head pin. To ease the die insertion, keep die/head release pin depressed.
- Insert the die in the seat on the head of main ram until it is locked by die/ram retainer pin. To ease this operation, keep die/ram release pin depressed.
- Insert the conductor in the connector.
- Position the connector between the dies and ensure the correct location of the crimp.
- Set the HT131-C tool on release position by rotating main hanle; open the moveable handle.
- Rotate main handle to operating position .
- Operate moveable handle for lower die advancement. This first stage rapidly closes the dies to the connector.
- Never place the tool under pressure without inserting the dies, as this could cause damage to the head and the ram.
- Make sure the dies are exactly positioned on desired crimp point, otherwise re-open dies and position the connector again.
- 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.
- Rotate the main handle to release position .
- Close handles thoroughly: the ram will then retract, with the consequent opening of the dies.
- Retract thoroughly the ram.
- Keeping handles closed rotate further the main handle to rest position ; the moveable handle will be thus locked.
- Store the tool in the case.
To replace dies operate as follows (Fig 2):
Upper die (91)
- Take the die off its guide by pushing the die/head release pin (32)
- Insert replacement die until secured by the die retaining pin (34).
Lower die (90)
- Take the die off its guide by pushing the die/ram release pin (38).
- To facilitate this operation an advancement of 15÷20mm of the ram (28) is suggested.
- Insert the new die in its guide till die/ram retainer pin (39) will hold it properly.
