Pre-Insulated Cable Sleeves for LV ABC Networks

Key Features

  • Designed for LV aerial bundled cable (ABC) systems

  • High-purity aluminum sleeve with contact grease

  • UV- and weather-resistant insulated cover

  • Elastomeric sealing caps for superior water tightness

  • Color-coded ends for easy conductor size identification

  • Tested for dielectric strength under water

  • Suitable for stranded aluminum conductors

Operating & Performance Characteristics

  • Operating Voltage: ≤ 1 kV

  • Dielectric Test: 6 kV under water for 1 minute

  • Mechanical Strength:

    • Up to 80% of conductor breaking load (self-supporting system)

    • 100% breaking load for insulated neutral messenger

Pre-Insulated Cable Sleeves are designed for reliable connection of low-voltage aerial bundled cables (LV-ABC), including phase conductors and neutral messenger lines.

Manufactured from high-purity aluminum and equipped with a weather-resistant insulation sheath, these sleeves provide excellent electrical continuity, mechanical strength, and long-term protection against moisture, corrosion, and environmental aging. Pre-filled contact grease and elastomeric sealing rings ensure superior waterproofing, making the sleeves suitable for outdoor distribution networks.

International Standard Compliance

  • EN 50483-4 – Insulated connectors for LV ABC systems

  • NF C33-021 – French standard for pre-insulated connectors

  • ESI 43-14 – Mechanical and electrical performance

  • RoHS Compliant

Construction & Materials

  • Sleeve Material: Aluminum ≥ 99.5%

  • Insulation: Weather- and UV-resistant polymer

  • Sealing: Elastomeric ring with silicone contact grease

  • Design: Pre-insulated compression sleeve with central stop

Inspection & Testing

  • Visual inspection

  • Dimensional verification

  • Mechanical load test

  • Dielectric test at 6 kV under water

  • Heat cycling and corrosion resistance tests

Installation Guide

  1. Strip the cable insulation to the required length.

  2. Insert stripped conductor fully into the TX-MJPT sleeve until it reaches the stop.

  3. Crimp over the insulation according to the markings on the sleeve.

  4. Use the recommended crimping die size.

  5. After crimping, electrical contact and sealing are achieved automatically.

  6. Visually inspect the joint for proper compression.

Pre-insulated cable sleeves ensure waterproof, reliable connections for LV ABC overhead distribution networks. Pre-Insulated Connector.
