CentraCore OPGW cable by Telexc is a compact, dual-function overhead ground wire that combines lightning protection, fault current dissipation, and high-capacity fiber-optic communication. Designed with a central stainless steel tube inside a hardened aluminum pipe, the cable offers excellent crush resistance, thermal protection, and mechanical strength while safeguarding fibers from stress. Color-coded fiber bundles (12 fibers per bundle) simplify splicing and field handling. Its lightweight, small-diameter profile allows easy installation on new or retrofit transmission lines without affecting tower loading. CentraCore OPGW supports up to 96 fibers in a consistent cable diameter, ensuring reliable long-term performance and reducing spare part requirements for utilities.

International Standard Compliance

  • IEEE 1138 – Cable

  • IEC 60794-4 – Cable

  • TIA 598-D – Fiber

  • ASTM B415 – Aluminum Clad Steel (ACS) Wire

Construction & Materials

  • Central Fiber Core: Laser-welded, hermetically sealed stainless steel tube

  • Outer Pipe: Thick-walled aluminum for crush resistance

  • Strands: Aluminum-clad steel and aluminum alloy wires for mechanical and electrical performance

  • Fiber Grouping: Bundles of 12 color-coded fibers

Installation Guide

  1. String using conventional conductor installation methods.

  2. Ensure proper sheaves/pulleys to prevent crushing.

  3. After installation, strip the outer wires to access the central aluminum pipe.

  4. Cut aluminum pipe with a ring cutter and organize fiber bundles for splice trays.

  5. Supports sectionalized installations to reduce line losses.
