Plastic tube encased in a metallic Tube
Composit Fiber Optic Overhead Ground Wire(OPGW) is a composite overhead optical groundwire that provides high capacity communication channels to service present and future needs.
SFPOC-PLASTTM is a new OPGW that can be applied to a very high voltage power transmission system where induced current will not flow through ground wires. A non-metallic tube placed in the stainess steel tube insulates the metallic wires from the structures at the entry of spice box. SFPOC-PLASTTM helps in substantially reducing the loss due to circulation of induced current through the ground wire.
The cable ends of SFPOC-PLASTTM are easy to handle especially at the time of accessing the optical fibers for splicing. The non-metallic tube eliminates the risk of damage caused to the fibers by the edge of the metallic tube while removing it for splicing of fibers.
The SFPOC-PLASTTM OPGW cable is designed to meet the specific requirement of the user in respect to short circuit capacity, tensile strength, fiber count and fiber type complying to ASTM, IEC and IEEE standards.
SFPOC provides with its products a comprehensive range of services,including OPGW hardware, installationsupervision, type testing and training.
Optical Design Features
SFPOC-PLASTTM features optical fibers placed loosely in a plastic tube embedded in a hermetically sealed stainless steel tube.
The optical fibers have low signal attenuation and wide band width allowing for long distance, high capacity communication.
Optical fibers are free from crosstalk and are not subjected to electromagnetic interference and polarization. They provide secure high quality signal transmission.
Groundwire Design Features
Aluminum-Clad Steel and Aluminum Alloy wires are stranded around a central optical unit.
The Aluminum-Clad Steel wires and Aluminum Alloy wires provide the mechanical strength to withstand installation and operating condition, while achieving the conductivity needed to control temperature rise during short circuit fault conditions.
