How To Install Piercing Wire Clips: Branch Cable Insertion Into End Caps
To install a piercing wire clip properly, push the branch conductor into the rubber end cap until it stops against the inner wall. Position the main conductor into the open channel, then turn the shear-bolt clockwise with a six-point socket wrench until the hex head snaps off completely.
Technical Specifications & Selector Guide
Choosing the right insulation piercing clamp depends on conductor cross-section, operating voltage, and core material. Incorrect sizing leads to overheating or loose electrical connections.
| Cable Application | Main Line Range | Branch Line Range | Target Shear Torque |
|---|---|---|---|
| Low-Voltage Overhead | 16 – 95 mm² | 4 – 35 mm² | 13 Nm |
| Medium-Voltage Line | 50 – 240 mm² | 25 – 120 mm² | 18 Nm |
| Street Lighting Feeders | 16 – 50 mm² | 1.5 – 10 mm² | 9 Nm |
Tip: Keep outer cable sheaths clean. Dust or debris trapped under teeth creates localized high resistance during current transmission.
Step-by-Step Installation Workflow
Correct assembly of an ipc cable connector ensures continuous current flow and maintains IP67 waterproof protection across aerial distribution lines.
1. Seating the Branch Wire
-
Slide the elastomeric cap onto the tap port.
-
Push the unstripped branch conductor straight into the housing.
-
Confirm the wire end presses firmly against the internal end stop.
2. Positioning the Primary Line
-
Snap the main conductor into the primary channel without removing insulation.
-
Keep the main body perpendicular to the line to balance contact pressure.
-
Spin the shear-bolt down by hand to stabilize the assembly.
Torque Application & Post-Installation Inspection
Apply steady pressure to the shear-bolt using a dedicated six-point socket. The contact blades breach the insulation layer, embedding into aluminum or copper conductors without damaging inner strands.
Quick Verification Checklist
-
Torque Shear: The upper hex nut severed cleanly, leaving the lower permanent head intact.
-
Weather Seal: The rubber cap compressed evenly around the branch jacket, forming a tight barrier.
-
Mechanical Alignment: The installed ipc insulation piercing connector sits straight with zero tilt along the line axis.
This systematic verification guarantees long-term dielectric strength, prevents moisture ingress, and minimizes voltage drop under extreme weather conditions.
