The TX-IPC-LVN-03  LV Insulation Piercing Connector 35–70 mm² / 35–70 mm² provides safe and reliable branching of low-voltage ABC conductors. It enables secure connections between insulated aluminium or copper conductors without stripping insulation. Its single shear-head bolt allows controlled torque to penetrate insulation and optimal electrical contact while maintaining the mechanical integrity of the conductors. It offers long-term performance in outdoor environments. Ideal for service line systems, street lighting, and building electrical systems where a single-tap connection is sufficient.

Standard: NFC 33 020, ANSI C119.5, EN 50483-4

Construction & Materials:

  • Body: PA66 Fiberglass Reinforced Thermoplastic,  High-strength, UV-resistant thermoplastic for durability and insulation.

  • Teeth: Tinned copper alloy/ Copper/Aluminium Teeth for excellent conductivity and corrosion resistance.

  • Bolts: Hot-dip galvanized or stainless steel with Zinc Alloy Shear Head for torque control.

  • Sealant: Pre-filled waterproof grease ensures a watertight connection and corrosion protection.

  • End Cap: Integrated PVC Cap, which prevents contamination and loss during installation.

  • Color: Black

Performance & Reliability:

  • Watertightness: Tested at 6 kV for 1 minute under water.

  • Electrical Contact: Teeth penetrate insulation without conductor damage.

  • Mechanical Strength: Maintains cable integrity under load and vibration.

  • Environmental Resistance: Performs reliably in UV, rain, and temperature variations.

  • Maintenance-Free: Long service life with minimal degradation over time.

  • Safety: Live-line installation possible under non-load conditions.

Installation Guide

  1. Insert main and branch conductors into the connector grooves.

  2. Tighten the shear-head bolt using a dielectric torque wrench until the head shears off to ensure correct torque.

  3. Verify proper seating and a waterproof seal before energizing.

  4. No insulation stripping required.

  5. Suitable for energized mains if not under load.
