Optical Power Ground Wire (OPGW Cable)
Description of OPGW
The OPGW optical cable integrates optical fibers inside the ground
wire of overhead high-voltage transmission lines, creating a secure
and efficient communication system along the power network. With
its dual role of grounding and data transmission, OPGW ensures both
power system protection and reliable communication. The metallic
wire structure provides excellent mechanical strength, stability,
and long service life. Compared with conventional optical cable
installations, OPGW significantly reduces construction time and
overall project costs. It is widely used in power transmission
projects, substations, and smart grid communication systems.
OPGW Optical Cable Characteristics & Advantages
Advanced stainless steel tube technology filled with water-blocking
compound for maximum fiber protection.
High tensile strength and compact structure ensure durability in
harsh environments.
Low interference between power grid and communication network even
under short-circuit conditions.
Easy installation—compatible with common ground wire specifications
and can directly replace existing ground wires.
Excellent lightning resistance and stable performance over long
spans.
Cost-effective solution for integrating communication into power
transmission infrastructure.
OPGW Cable Description
Application
OPGW is mainly applied in power communication systems together with
related accessories. It supports relay protection, automatic
monitoring, and signal transmission when installed along
high-voltage power lines.
Structure
The Stranded Optical Ground Wire (OPGW) is manufactured with double
or triple layers of aluminum-clad steel (ACS) wires, or a mix of
ACS and aluminum alloy wires. Its design is optimized to meet the
needs of modern overhead power grids, ensuring both electrical
grounding and optical communication.
