Optical Ground Wire Central Loose Tube (OPGW central loose tube type) is a specific construction of Optical Ground Wire cable, primarily chosen for projects where low weight and small diameter are more critical than maximum rated breaking strength and short-circuit current capacity. OPGW (Optical Ground Wire) is a dual-function cable used on high-voltage transmission lines that simultaneously serves as a lightning protection ground wire and a high-bandwidth communication medium. OPGW, called Optical ground wire, is a dual-functioning cable used in overhead power lines that combines the functions of ground wire and communications. It can transmit telecommunications signals over long distances and at high speeds. It also serves as a grounding wire for electric power systems. So, it can replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of optical fibers. In addition, the OPGW cable is sheathed in a metal jacket. This metallic sheath also acts as a conductor and is ideal for power systems. OPGW conducts short-circuit current and shields the high-voltage conductors from lightning strikes. At the same time, it can provide a telecommunications path for internal and third-party communications. NEATEL has developed technical expertise in fiber optic cables and proven its capabilities in manufacture of energy efficient bare overhead power conductors. NEATEL has integrated these core strengths in its comprehensive OPGW solution that includes Optical Fiber Composite Ground Wire and related hardware.
