OPGW Cable

OPGW cable single aluminum tube single steel tube

Name: OPGW cable single aluminum tube single steel tube
Availability: InStock

OPGW (Optical Ground Wire) cable combines the functions of grounding and fiber optic communication in a single integrated solution for overhead power transmission lines. The central stainless steel tube protects optical fibers from moisture and extreme environmental conditions including lightning strikes, while single or double layers of aluminum clad steel (ACS) wires provide mechanical strength and electrical conductivity. Designed to IEC 60794-8 and IEEE 1138 standards, our OPGW cables are engineered for 110kV and above high-voltage transmission lines with various fiber counts and mechanical ratings to match specific tower span and short-circuit current requirements.

OPGW cable (optical ground wire) is a type of cable that is used in overhead power lines. Fibers for OPGW are single mode type. The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.

Frequently Asked Questions

1. What is OPGW cable and how does it differ from ADSS?

OPGW (Optical Ground Wire) serves dual purposes as both a ground/lightning protection wire and a fiber optic communication cable. Unlike ADSS which is all-dielectric and installed separately, OPGW replaces the traditional ground wire on the top of transmission towers. OPGW is used for new line construction or major renovation of lines ≥110kV, while ADSS can be installed on existing live lines.

2. What fiber counts are available for OPGW cable?

Our OPGW cables support fiber counts ranging from 12 to 60 fibers, using single-mode fibers compliant with ITU-T G.652D standard. Custom fiber counts and types (G.655, G.657) are available upon request.

3. Does installing OPGW require a power shutdown?

Yes, OPGW installation typically requires the power line to be shut down because it replaces the existing ground wire at the top of the tower. This is why OPGW is primarily used for new line construction or major renovation projects where planned outages are feasible.

4. What mechanical ratings should I specify for my project?

Key parameters include RTS (Rated Tensile Strength) in kN and short-circuit current capacity (kA²s). These depend on your tower span distances, ice/wind loading conditions, and the electrical fault current of your transmission line. Our engineering team can help you select the optimal specification.
