Product Description

Tratos optical fibre overhead ground wire (OPGW) containing 90 single-mode fibres and aluminium-clad steel wires.

Tratos combine this experience to manufacture a wide range of sizes and types of OPGW cables which have the dual performance functions of a ground wire with telecommunications capabilities. In this design 90 single-mode fibres are encased in 5 thixotropic jelly-filled loose tubes each containing 18 colour-coded fibres which are laid up around an FRP strength member, wrapped with thermal barrier tapes then encased in a dry seamless aluminium sheath creating an enclosed, protected environment for the optical fibres. 

Surrounding this aluminium tube is a single layer of aluminium-clad steel wires (20SA-A to BS EN 61232) which affords both strengths and increased corrosion protection in hostile environments.

This Tratos design of cable provides the optimum balance between strength and conductivity, the lay lengths are carefully chosen to ensure that the conductor is neutral along its central axis giving excellent handling characteristics without any tendency to corkscrew or retract when being taken from the delivery drum during installation.

Standards
IBERDROLA NI 33.26.31 
ITU-T G652/D
BS EN 61232

Application
Tratos optical fibre overhead ground wire (OPGW) Cables are designed to run between the top of high voltage electricity pylons to provide the grounding and lightening protection required by overhead transmission lines combined with a high-speed optical transmission path, along new or existing low and medium tension network lines. The aluminium-clad steel offers increased corrosion protection and is commonly specified for coastal applications.
