Selecting & Positioning Die Sets

Fig 1 Die Assembly & Positioning

Die Assembly (Fig 1)

1. Dedicated Dies

• Select the appropriate die set for the connector to be crimped using ECW-H3D tool
• Extract the die retaining pin (09) from the tool head
• Insert the lower die (26b) and align the groove (30) in the die, with the guide pins (15) in the crimp tool presshead
• Insert the upper die (26a) into the tool head
• Insert the die retaining pin (09) in the head and through the upper die. Ensure the spring loaded pin (10) is fully released

1. Semi-circular Dies

• Select the appropriate die set for the connector to be crimped using ECW-H3D tool
• Extract the die retaining pin (09) from the tool head
• Insert the lower half of adapter Cembre AU230-130D (31b) and align the groove (30) in the adapter, with the guide pins (15) in the head
• Insert the upper half of the adapter Cembre AU230-130D (31a) into the head
• Insert the die retaining pin (09) into the head and through the adapter. Ensure the spring loaded pin (10) is fully released
• Press pin (35) on lower part of adapter, AU230-130D and insert one half of the die set until secured by locking pin (34)
• Press pin (32) on upper half of adapter, AU230-130D and insert the other half of the die set until secured by locking pin (33)

♦ Warning: Before carrying out further operations make sure the die-stop pin is completely inserted; a partial insertion may cause damage to the head.

Dies Positioning

• Insert the conductor into the connector.
• Locate the connector between the dies at the desired crimp position. – Operate the pump until the dies touch the connector barrel

♦ Warning: Make sure that dies are exactly positioned on the area to be crimped; otherwise re-open dies and reposition the connector.

Cable Cutting Blade Replacement

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).

Maintenance Of Flexible Hose In Cembre PO7000 Hydraulic Pump

Cembre PO7000 Hydraulic Foot Pump

• Uploaded by Chris Dodds - Thorne & Derrick Sales & Marketing Manager

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 

1. Hold the pump base (38) in a vice, keeping the hose above the level of the vice
2. Using a 19 mm fl at spanner, unscrew the hose from the pump body, while holding the coiled hose
3. Carefully clean the thread of the pump body to remove any residual sealing materials
4. Restore the gasket (tefl on tape) on the (male) thread of the new hose
5. Connect the new hose, tightening the relevant nut to the correct torque ratio: 50 Nm (37 lbf.ft)
6. Eliminate air in the hose as follows: unlock the pedal from the latch
7. Depress the ball of the female quick coupler fitted to the end of the hose and pump slowly several times, until the oil flows
8. Check the oil level and top up as described in operating manual

The Cembre TC120 cutting head is robust and requires very little daily maintenance – ensuring you follow the instructions below will help to maintain the optimum performance of the tool by cleaning and storing correctly:

Accurate Cutting Head Cleaning

Dust, sand and dirt are a danger for any hydraulic device. It is essential that after every use the cable crimping or cutting tool should be wiped with a clean cloth removing all residue paying special attention to pivots and moveable joints

Replacement Of The Automatic Quick Male Coupler

• To replace the automatic coupler from Cembre TC120 proceed as follows:
• Remove the old coupler.
• Carefully clean the thread to remove old sealant.
• Apply teflon tape to the thread.
• Fit the new coupler and tighten to 30 Nm (22 lbf ft)
