Category Insights

OPGW (Optical Ground Wire) cables are special dual-purpose cables. They combine fiber optics with power line protection. These cables replace traditional ground wires on transmission towers. The metal part shields against lightning strikes. The fiber inside provides high-speed data transmission. They're used by electric utilities for smart grid communications.

OPGW cables are mainly used by power companies. They protect high-voltage power lines from lightning. They carry communication signals along power routes. Utilities use them for grid monitoring and control. They enable smart meter data transmission. They also provide backup telecom networks during emergencies. Perfect for power line communication systems.

OPGW has aluminum or steel outer layers. It serves as both ground wire and fiber cable. Regular fiber cables don't provide lightning protection. OPGW is installed on power line towers. Normal fiber cables are buried or strung separately.

Must be installed by trained power line crews. Requires special tensioning equipment. Needs careful handling to avoid fiber damage. Installation follows strict safety protocols. Typically done during power line construction or upgrades.

Standard OPGW carries 24 to 144 fibers. Some designs hold up to 288 fibers. Fiber count depends on cable diameter. More fibers allow more communication channels. Utilities choose based on current and future needs.

Typically lasts 30-40 years. Metal sheath protects fibers long-term. Resists weather and environmental damage. Outlasts many other cable types. Requires minimal maintenance over its life.

Yes, but it requires line shutdowns. Special crews can replace old ground wires. Sometimes installed during routine maintenance. Retrofit projects need careful planning. New construction is the ideal time for installation.
