Product Description:

An aluminum layer is extruded outside the PBT cable core to form an aluminum tube, with a thermal insulation layer protecting the core. This structure reduces electrochemical corrosion between different metal materials. It is commonly used for old line renovations, low-voltage lines, and heavily polluted coastal chemical environments with severe corrosion.

Technical Features:

Optical fibers receive excellent mechanical and thermal protection

Excellent resistance to lateral pressure and high short-circuit current capacity

Small outer diameter, lightweight, no need for additional supporting towers or poles

Color-coded tubes for easy identification of multi-core OPGW and spliced fibers

Fibers remain stress-free at maximum allowable cable stress

Layer-stranded wires provide superior mechanical and electrical performance

Compatible with conventional ground wires
