OPGW Cable
OPGW cable Stranded PBT tubes
The OPGW stranded PBT tube cable features multiple PBT (Polybutylene Terephthalate) loose tubes stranded around a central strength member within a stainless steel tube, providing superior fiber management and higher fiber counts compared to single-tube OPGW designs. Surrounded by double or triple layers of aluminum clad steel (ACS) wires, this cable delivers the combined ground wire and fiber optic communication functions required for modern high-voltage transmission lines. Engineered to IEC 60794-8 and IEEE 1138 standards.

Frequently Asked Questions
1. What are the advantages of stranded PBT tubes vs single tube OPGW?
Stranded PBT tube OPGW supports higher fiber counts (up to 144 vs 60 in single tube) with organized fiber grouping by tube color. This simplifies splicing at intermediate towers where only specific fiber groups need to be accessed, and provides better fiber identification during maintenance.
2. What fiber types are available in OPGW stranded PBT tubes?
Standard offering includes G.652.D single-mode fibers. G.655 (NZ-DSF) and G.657 (bend-insensitive) fibers are available upon request. Each PBT tube typically contains 4–24 fibers with color-coded identification per TIA/EIA-598.
