Overhead Conductor - HV

TERNA San PellegrinoTratos Overhead Conductor Cable Innovative Design

Following the development, testing and successful installation of a completely new design of hybrid Overhead Conductor Cable for use in overhead lines, Tratos have 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 have further developed and improved the concept; Tratos can now offer a bespoke design of 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.

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

BETTER BY DESIGN – Current carrying capacity is twice that of traditional designs. Reduced weight and strain allow existing pylons and standard installation techniques to be used.

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
