Tratos OHC CFCC (Carbon Fiber Composite Conductors) – Overhead Conductor

Cable Innovative Design High-Temperature Low Sag Cables

Following the development, testing, and successful installation of a completely new hybrid overhead conductor cable for use in overhead lines, Tratos has proved the concept and principle that this innovative design avoids the limitations of traditional conductor designs. The initial Tratos design was based upon a high load carrying carbon fibre core with two compact, space-saving, segmental thermal resistant aluminium alloy (AT1) wire layers applied helically around. Tratos has further developed and improved the concept; Tratos can now offer a bespoke design of the centre matched to the actual circuit and installation conditions, with one, two or three layers of either circular or segmental wires to meet the existing or forecast current carrying capacity.  

Most importantly, these Tratos Overhead Conductor Cable innovative designs are not governed by existing materials and technology, where any increase in transmitted power results directly in either an increase in size and, hence, the weight of the conductor or an increase in the operating temperature above the recommended maximum operating temperature.

APPLICATIONS — These new innovative hybrid conductors are especially suitable as fast and cost-effective replacements for traditional ACSR conductors in short and medium spans in all topographical locations.

BETTER BY DESIGN — The current carrying capacity is twice that of traditional designs. Reduced weight and strain allow the use of existing pylons and standard installation techniques.

MORE STRENGTH, LESS SAG — Greater tensile strength to withstand snow, ice and wind loadings. Less sag and increased ground clearance at the maximum current rating.

ECONOMIC BENEFIT — Tratos Overhead Conductor Cables reduce cost and make easier installation alongside increased power transmission

Notes on handling CFCC: CFCC is a composite material consisting of carbon fibres and a matrix resin. As CFCC is different from steel members, special care should be taken when handling it, i.e., not to cause flaws, deformation, or deterioration. Refrain from dropping hard and heavy objects (such as hammers), sparking welding/fire on CFCC, or bending CFCC steeply. CFCC damaged by any of these should be discarded.

These bare overhead conductors, including CFCC, form the backbone of electrical transmission and distribution systems, ensuring electricity’s reliable and efficient flow to homes and industries worldwide. Their diverse designs and materials cater to a wide range of environmental and operational conditions, making them an indispensable part of modern electrical infrastructure.
