LV-HV Cable Crimping Tools


Cembre HT45-E hydraulic crimping tool is a manual tool for the crimping of low and high voltage cable lugs, splices and connectors up to 150sqmm.

Cembre HT45-E 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 will also by-pass the oil supply when maximum pressure has been reached.

The Cembre HT45-E crimping tool is suitable for installing electrical compression connectors for conductors up to 150sqmm (300 MCM).

  • Rated Operating Pressure: 600 bar (8,700 psi)
  • Dimensions: Length 346mm, Width (handles closed) 130mm, Width (handles open) 250mm
  • Cable Crimper Weight: 2kg
  • 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 HT45-Echeck the oil level in the reservoir. If necessary fill oil level to the top lip and remove any excess air from the reservoir.

Dust, sand and dirt are a danger for any hydraulic device. Every day, after use, the HT45-E tool must be cleaned with a clean cloth, taking care to remove any residual, especially close to pivots and moveable parts.

For storage and protection the Cembre HT45-E tool is supplied in a robust carrying case for storage of the crimping tool and up to 20 sets of die sets.

The following information provides some general advice of the operation and maintenance of Cembre HT45-E crimping tool – for further information contact Thorne & Derrick.

Fig 3 HT51 Maintenance

Air in the hydraulic circuit may affect the performance of the Cembre HT45-E tool; e.g. no lower die advancement, slow advancement of the lower die; lower die pulsating.

In this case proceed as follows:

To purge air bubbles from hydraulic circuit

a Hold HT45-E tool upright in a vice with handles open (Fig. 3).

b Unscrew the main handle (04) from the body (13) to expose the rubber oil reservoir (03).

c Remove reservoir cap (02).

d Operate moveable handle (36) several times, in order to advance the ram (16).

e Press the pressure release lever (44) to retract the ram (16), discharge oil pressure from the circuit and return all oil to the reservoir.

f Repeat points (d e) five times, to ensure all air bubbles in the hydraulic circuit are purged into the reservoir.

g Remove all air from reservoir.

If the oil level is low,top up as directed in paragraph 4.2.

h Fit reservoir cap (02).

i – Assemble main handle (04) to Cembre HT45-E tool body.

If the tool continues to malfunction, return the tool for service/repair as detailed in § 5.

Oil top up

Every six months check the oil level in the reservoir. If necessary, top up the oil level to the top lip of the reservoir and remove all air from the reservoir, see 4.1, points a, b, c and e, finally, complete with operations h and i.

Always use clean recommended oil, see § 1.

Do not use old or recycled oil.

Do not use hydraulic brake fluid.

➡ Ensure that disposal of used oil is in accordance with current legislation.
