Crimping Aluminium Cables
Hydraulic Crimping Presshead Accessories
Pre-Rounding Conductor (For Sectoral Cables)
Ensure all aluminium conductors are thoroughly cleaned using approved and suitable cable cleaning wipes prior to crimping.
From the table select the Cembre adaptors and pre-rounding dies for the appropriate conductor size.
Insert the upper adaptor Cembre AU130- and lower adaptor AC130–P into the head as per below.
Insert the pre-rounding die (94) into the AC130–P adaptor.
Position the conductor into the pre-rounding die (95) and locate the pre-rounding die (95) in the adaptor AU130.
Ensure that the pre-rounding die is correctly located in the adaptor with its upper slot in line with the internal adaptor pins.
Operate the hydraulic foot pump until the dies are fully closed, such as Cembre PO7000.
Release the hydraulic pressure and remove the compacted round conductor.
Die Insertion
Connector Cable Crimping
Remove the pre-rounding dies and the adaptor AC130–P from the presshead.
From the table select the containing die and indentor recommended for the conductor size.
Insert the indentor into the ram (09).
Insert conductor into the connector.
Locate the connector into the containing Cembre die then locate the containing die in the adaptor.
Commence indent crimping from the barrel end for both splices and terminals following the sequence shown below:
- For every operation ensure the die is correctly located in the adaptor with its upper slots in line with the internal adaptor pins
- Each indenting operation is completed when indentor and die are fully closed; it is recommended to continue pumping until the maximum pressure valve is activated and a “click” is heard
Adaptor Fitting & Removal
- Insert the upper adaptor AU130 (98) into the U-fork head (14) until secured by the locators (15).To remove the adaptor from the U-fork head, push the adaptor from the locators and slide out
- To insert the adaptor AC130–P(91), press the die release pin (12).
Insert the adaptor into the seat of the ram (09), until secured by the retaining pin (11). To facilitate this operation, an advancement of 3÷4 mm (0.11 – 0.16 in.) of the ram (09) is suggested. To remove the adaptor, press the die release pin (12) and slide the adaptor from the ram (09).
Crimping Dies, Indentors, Pre-Rounding Dies – Fitting & Removal
- The containing die (96) and upper pre-rounding die (95): are located in the adaptor AU130-… (98) by grooves in the upper face.
- The lower pre-rounding die (94): is inserted or removed from the adaptor AC130-P (91) by pulling the release button (92).
- The indentor PS130…/E (93): is inserted into the seat on the ram (09)

Cembre TC055
Fig 2 & Fig 3 Cembre TC055 Blade Replacement
The following instructions should be read in conjunction with the image above.
After extended use the blades of the Cembre TC055 may lose their cutting edge.
Replace the blades as follows:
Lower Cable Cutting Blade
Remove locking pin (4) and open the cutting tool head.
Operate the pump to advance the lower cutter blade (24) until split pins (22 and 23) are visible on the ram (18).
Remove split pins (22 and 23) using a drift and remove the lower cutter blade.
Insert the new blade and secure with spring pins.
♦ Warning: Before closing the cutting tool head release the oil pressure and retract the lower cutter blade otherwise the blade may hit the lower blade edge and damage it.
Upper Cable Cutting Blade
With the lower cutter blade fully retracted, the tool head closed and the locking pin (4) fully secured, hold the tool on the blade spacer (1) or (26) in a bench vice (Fig 3).
With a 6mm wrench, unscrew 4 screws (28), remove the two holding plates (29) and the upper cutter blade (25) noting the position of the cutting edge bevel.
Insert the new cutting blade, noting the position of the cutting edge bevel.
Fit the 2 holding plates (29) and secure with 4 screws (28) with relevant washer (30).

Cembre PO7000 Hydraulic Foot Pump
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 useful instructions about how to correctly maintain the flexible hose in the Cembre hydraulic PO7000 hydraulic pump – supplied with 10 foot long high pressure flexible hose complete with an automatic, female, quick-coupler suitable for connection to a Cembre hydraulic crimping or cutting head.
The following excerpts are taken from the Operating Manual of Cembre PO700.
Cembre PO700 is a foot operated double speed hydraulic pump developing a maximum pressure of 10,000 psi for installing cable crimps, lugs and connectors.
Maintenance Of Flexible Hose
Cembre PO7000 Pump stored in plastic case VAL-P21.
The flexible hose is designed for high-pressure operation and should not be tightly bent, knotted, kinked or squashed.
♦ Warning: Take care when storing the pump in the plastic case, the hose should be coiled in wide loops.
High pressure flexible hoses are subject to a natural ageing process which can result in a reduction in performance potentially affecting safety of the operator and functionality of the hydraulic pump. In order to ensure safe use of the PO7000, Cembre recommends replacing the hose within 10 years from the date printed on the tool fittings. Pumps in the PO7000 range are supplied with a standard or non-conductive hose.
♦ Warning: Before using the pump always check the integrity of the flexible hose and the quick couplers making sure there are no abrasions, cuts, deformations or swellings.
Fig 8 Hydraulic Pump Position For Replacement Of High Pressure Hose
Replacement Of The Pressure Hose
- Hold the pump base (38) in a vice, keeping the hose above the level of the vice
- Using a 19 mm fl at spanner, unscrew the hose from the pump body, while holding the coiled hose
- Carefully clean the thread of the pump body to remove any residual sealing materials
- Restore the gasket (tefl on tape) on the (male) thread of the new hose
- Connect the new hose, tightening the relevant nut to the correct torque ratio: 50 Nm (37 lbf.ft)
- Eliminate air in the hose as follows: unlock the pedal from the latch
- Depress the ball of the female quick coupler fitted to the end of the hose and pump slowly several times, until the oil flows
- Check the oil level and top up as described in operating manual
