Cembre ECW-H3D Presshead (400-630sqmm Crimping Tool)

Cembre ECW-H3D Presshead (400-630sqmm Crimping Tool)

Cembre ECW-H3D is a hydraulic presshead crimping tool complete with male quick automatic coupler for connection to a hydraulic pump with a working pressure of 10,000 psi max.

Adaptor type AU230-130D is available as an optional extra enabling the tool head to utilise the semi-circular slotted dies which are common to most 12 tons tools (U or C shaped dies) – the hydraulic crimp head is suitable for LV HV cable lugs, connectors and splices up to 630sqmm.

The ECW-H3D hydraulic crimping head has an available series of dies for the compression of DIN electrical connectors – refer to the table below.

The presshead weighs 5.5kg and is supplied in a robust steel case which is suitable for storage of the crimper head tool – used to joint and terminate lugs or connectors on LV MV HV cables including 11kV/33kV medium/high voltage electrical systems.

User Instructions

  • Cembre ECW-H3D tool is equipped with a “self-lock” quick male coupler which can be connected to a Cembre pneumatic or electric pump
  • Select the appropriate die set for the connectors (crimp lugs or splices) for use with the presshead
  • Open the latch and release the upper die holder of the hydraulic crimping tool or presshead
  • Insert one die into the upper die holder and one die into the lower die holder
  • Close the latch on the presshead
  • Insert the conductor into the connector (crimp lug or splice)
  • Locate the connector between the crimping dies at the desired crimp position
  • Operate the pump to advance the main ram of the Cembre ECW-H3D
  • Continue to operate the pump, the ram will gradually advance until crimp dies meet
  • Recommended to keep pumping until the maximum pressure valve is activated and a “click” is heard
  • After crimping completion press the release lever to release oil pressure
  • Recommend only Cembre Lugs & Connectors are used with Cembre tooling

Hydraulic Foot Pump Options

Connecting the ECW-H3D to hydraulic foot pump is quick and easy using the male Quickfit automatic coupler to deliver 700bar compression force – the ECW-H3D is compatible with both the Cembre PO7000 2-speed foot operated pump or Cembre B70M-P24 portable 24v electro-hydraulic pump.

For crimping application using Cembre ECW-H3D tools including heavy duty copper tube connectors, nylon insulated copper connectors, copper “C” connectors and high voltage lugs/connectors please contact T&D.

Contact T&D to discuss crimping cables at MV-HV, including 11kV-33kV, to ensure correct Cembre tool, lug/splice and die set selection – visit battery crimping tools for repetitive crimping of cables without strain injury or worker fatigue.

Full range of battery cable cutting tools also available.
