Product Overview

The Cembre RHC131 develops a nominal crimping force of 130kN and uses the standard die set compatible with other 130kN tools and heads, making it a versatile option for utility, contractor and industrial cable work.

Cembre RHC131 is a hydraulic crimping head engineered for the installation of electrical connectors on conductors from 10mm² to 400mm².

This hydraulic crimping head features an open C-head configuration to simplify positioning around connectors and conductors. The head is supplied complete with a male quick-release coupling with automatic locking for secure connection to the hydraulic hose and pump.

RHC131 presshead will accept die sets common to Cembre 130kN hydraulic crimping tools.

For operation, the RHC131 must be combined with a hydraulic pump with a maximum working pressure of 700 bar. It supports multiple crimping geometries including hexagonal, oval, indent and radial profiles to suit a wide range of connector types.

Compact in design at 234 x 129 x 76mm, the RHC131 is suitable for professional cable jointing, substation works and electrical installation projects where reliable and repeatable crimping performance is essential.

Cembre RHC131 Hydraulic Crimping Head

User Instructions

Operation Stage	User Instructions
Connection	• Connect the male quick-release coupling securely to a compatible hydraulic hose and pump. • Ensure the hydraulic system used does not exceed 700 bar working pressure.
Die Selection	• Select the correct die set for the connector and conductor size. • Use standard dies suitable for 130kN Cembre-compatible tools and heads.
Positioning	• Open the C-head around the connector and conductor assembly. • Check that the connector is aligned correctly before applying pressure.
Crimping Cycle	• Operate the hydraulic pump until the crimp is completed. • Follow the recommended crimping sequence for the connector type being installed.
Disconnection	• Release hydraulic pressure before disconnecting the head. • Clean and store the tool after use to maintain performance.

Die Set Options

The Cembre RHC131 hydraulic crimping head is compatible with standard 130kN die sets used across Cembre pressheads and hydraulic crimping tools.

A wide range of die set options is available for crimping electrical connectors and cable lugs across LV and HV cable applications up to 400sqmm.

Compatible die sets are available for different conductor sizes, connector types and crimping profiles including hexagonal, oval, indent and radial compression requirements.

For technical guidance on selecting the correct dies for your connector and conductor size, contact Thorne & Derrick for product support and application advice.

Maintenance & Safety

Some Fault Diagnosis Tips

Problem	Solution
The head does not operate when connected to the pump.	Check that the quick-release coupling is fully locked and that the hydraulic pump is functioning correctly.
The crimp is incomplete or inconsistent.	Verify the correct die set is fitted and confirm the connector and conductor size are within the 10-400mm² operating range.
Hydraulic performance seems weak.	Inspect the hydraulic pump, hose and coupling for leaks, trapped air or pressure loss.
The head is difficult to position on the connector.	Confirm the connector type and die arrangement are suitable and use the open C-head correctly for access.

Routine Care

Keep the hydraulic crimping head clean and free from dirt, dust and metal debris.
Inspect the coupling and contact surfaces before and after use.
Store the tool in a clean, dry case to protect it during transport and storage.
Use only compatible dies, pumps and hydraulic accessories.

Note: Always use the tool with a compatible hydraulic system and follow the manufacturer’s operating instructions. Never exceed the maximum rated pressure.

Cleaning & Storage Of The Cembre RHC131

The Cembre RHC131 is a robust professional crimping head that requires limited daily maintenance. Ensure optimum performance by following these actions:

Wipe down the body and working surfaces after every use with a clean cloth.
Keep the quick-release coupling protected from contamination.
Store the RHC131 safely in its case or protective packaging to avoid impact damage.
Arrange periodic inspection and maintenance where required for heavily used tools.
