Ensure all tools are clean, calibrated where applicable, and suitable for medium-voltage cable installation.

5. Installation Procedure

5.1 Cable Preparation

Confirm the cable type, conductor size, insulation diameter, and termination dimensions against the approved drawings and connector selection table.

Cut the cable to the required installation length.

Remove the cable outer sheath carefully without damaging the metallic screen or insulation.

Prepare the cable screen and earth connection according to the manufacturer's instructions.

Remove the required length of insulation to expose the conductor.

Ensure the insulation surface is clean, smooth, and free from scratches, moisture, dirt, or contamination.

5.2 Connector and Adaptor Selection

Measure the cable insulation diameter.

Select the correct RPCT-24C adaptor code (A–H) based on the measured insulation diameter.

Adaptor Insulation Diameter

A 16.9–19.3 mm

B 18.3–21.0 mm

C 20.0–24.1 mm

D 23.1–27.0 mm

E 25.6–29.0 mm

F 27.7–32.6 mm

G 30.9–36.2 mm

H 34.0–39.5 mm

Select the appropriate mechanical lug according to the conductor cross-section.

Cable Cross Section Mechanical Lug

70–95 mm² RMVL-C 70-95/29

95–150 mm² RMVL-C 95-150/29

150–240 mm² RMVL-C 150-240/29

240–300 mm² RMVL-C 240-300/29

5.3 Mechanical Lug Installation

Insert the prepared conductor into the mechanical lug.

Ensure the conductor is fully inserted and correctly positioned.

Tighten the mechanical screw according to the manufacturer's specified torque and sequence.

Verify that the lug is firmly secured and that there is no movement between the conductor and lug.

Install the connecting stud as specified by the manufacturer.

5.4 Stress Control and Connector Body Installation

Install the stress control components in the correct position.

Apply the approved lubricant, if specified in the manufacturer's installation instructions.

Position the RPCT-24C connector body over the prepared cable.

Ensure the connector is fully seated and correctly aligned.

Install the insulating back plug where applicable.

Ensure the connector body is free from contamination and mechanical damage.

5.5 Earthing and Screen Connection

Connect the cable metallic screen to the earthing braid/earth connection.

Ensure the earth connection is mechanically secure.

Apply the specified mastic and sealing materials.

Check that the conductive outer layer of the connector is properly connected to the cable screen/earth system as required.

6. Inspection and Testing

After installation, perform the following inspections:

Verify correct connector and adaptor selection.

Verify cable conductor size.

Check mechanical lug installation.

Check tightening/torque requirements.

Check connector alignment and seating.

Check cable insulation for damage.

Check stress control components.

Check earthing and screen connections.

Check sealing and mastic application.

Ensure there are no visible gaps, contamination, or mechanical damage.

Perform electrical tests in accordance with the approved testing procedure.

The completed termination shall be inspected and approved by the responsible electrical supervisor before energization.

7. Quality Control

The installation shall comply with:

Approved project drawings and specifications

Manufacturer's installation instructions

HD 629.1 S2

IEC 60502-4
