Installation Guide (JJCD Grounding Series)

  1. Prepare the Conductor
    • Ensure the insulated conductor is clean and free from surface contaminants.
    • No stripping of insulation is required.

  2. Open the Clamp
    • Loosen the bolts until the conductor can be inserted freely into the connector slot.
    • Verify that the earthing ring (for 10 kV models) is properly aligned.

  3. Insert the Conductor
    • Position the main insulated conductor inside the clamp channel.
    • Ensure the cable is fully seated and correctly aligned with the piercing blades.

  4. Tighten the Bolts
    • Begin tightening the bolts evenly using a suitable wrench.
    • Continue tightening until the shear-head bolts break off automatically, indicating correct torque application.

  5. Verify Contact and Sealing
    • Ensure the clamp is fully closed and the piercing blades have established proper electrical contact.
    • Confirm that sealing caps are securely in place to maintain waterproofing.

  6. Final Safety Check
    • Inspect the connection for proper alignment, tightness, and insulation integrity.
    • Ensure grounding leads and accessories are attached according to system requirements.

  7. Commissioning
    • Once installation is confirmed, the grounding clamp is ready for operational use in temporary grounding, maintenance work, or system inspection.
