Why Choose the Cembre RHU450 Hydraulic Crimping Press Head?
The Cembre RHU450 (MPN: 2640151) is a heavy-duty 450 kN hydraulic crimping press head engineered for installing compression cable lugs, splices and connectors on large copper and aluminium conductors. Designed to operate with compatible 700 bar hydraulic pumps, it delivers powerful, consistent crimping performance for demanding industrial, utility and infrastructure applications.
Manufactured by Cembre, the RHU450 features a durable U-shaped head with retaining pin, allowing quick die changes while providing excellent access around large connectors. It accepts dedicated Cembre dies and, with the optional AU450-130D adaptor, can also use the semi-circular dies common to many 130 kN Cembre tools.
Suitable for crimping compression connectors on conductors up to 1000 mm², the RHU450 is ideal for high-current electrical installations, substations, renewable energy projects and heavy industrial applications where dependable cable terminations are essential.
