Cembre RHU520 Presshead (1200sqmm Crimping Tool)

Cembre RHU520 is a hydraulic presshead crimping tool complete with quick automatic coupler for connection to a hydraulic pump with a working pressure of 700 bar max.

RHU520 presshead will accept die sets common to Cembre 130kN hydraulic crimping tools.

Adaptor type AU520-130C is available as an optional extra enabling the head to utilise the semi-circular slotted dies.

The presshead weighs 18kg and is supplied in a robust plastic case which is suitable for storage of the crimper head tool and 20 sets of crimping dies – used to joint and terminate lugs or connectors on LV MV HV cables including 11kV/33kV medium/high voltage electrical systems in a typical range of 400-1000sqmm.
