During 2007 EPL Composite Solutions Ltd. (EPL) began working with Prof. Simon Rowland and Dr. Ian Cotton from the National Grid High Voltage Labs at the University of Manchester.

The aim was to combine their expertise – EPL in composite structures and the University in High Voltage Engineering – to create a team capable of developing an enabling technology to up-rate the operating voltage (e.g. from 275kV to 400kV) of existing infrastructure without the need to replace the pylon towers.

The majority of the current research and development being done by Arago Technology is focused on creating an electrically insulating transmission tower Cross-Arm. This Composite Cross-Arm is suitable for retrofit to existing transmission towers or as an option for new line build.

This technology is not limited to a specific tower size and can be adapted to suit any tower.

For the up-rating of existing lines, the Composite Cross-Arm allows tower voltages to be increased without any change to the overall tower structure or height. The increase in voltage will usually require a change in the conductor (the wire carried by the towers). Significant improvements in power transfer capability can be achieved through the combination of the Composite Cross-Arm with the use of a low sag novel conductor to increase current. Read More
