Irvine, CA – July 5, 2011 – Composite Technology Corporation (CTC) (OTC Bulletin Board: CPTC) is pleased to announce the installation of a 110kV line, using ACCC® conductor, for PGE Dystrybucja Bialystok in Poland.  The composite conductor was supplied by Lamifil using ACCC® core supplied by CTC Cable Corporation.

The 2 kilometer line, which is part of a line that runs between Bielsk Podlaski and Hajnowka (an urbanized area in Eastern Poland), was strung with ACCC® Helsinki conductor on existing steel towers. This conductor was selected in preference to a larger ACSR conductor due to the superior sag characteristics and higher capacity of the smaller ACCC® conductor, which allowed the existing towers to be used.  The ACSR solution would have required new, higher towers to be constructed. The installation was completed on June 22.  

Stewart Ramsay, President of CTC Cable Corporation commented, “We are very pleased that PGE Dystrybucja Bialystok has chosen ACCC® Helsinki conductor for this project. Poland is a great market, with a combination of economic growth, an appreciation of the ACCC® technology and the need for the value that it brings.  We believe that ACCC® conductors provide a viable option for transmission and sub-transmission lines where the combination of high capacity, low weight and low sag characteristics of the conductors can provide material benefits to distribution utilities in situations such as this. We look forward to being able to offer solutions to PGE on other projects in Poland and to other distribution companies in future.”

About CTC:

Composite Technology Corporation's patented ACCC® conductor technology enables superior performance of high voltage transmission and distribution electrical grids. ACCC® conductors use CTC's proven carbon fiber core which is produced by its subsidiary, CTC Cable Corporation, at its Irvine, California headquarters and delivered to qualified conductor manufacturers who produce and distribute ACCC® conductors to operators of electrical grids worldwide. CTC's conductor technology significantly reduces thermal line sag and can replace similar diameter and weight traditional conductors with its higher capacity and more energy efficient ACCC® conductor. It is an ideal conductor for both upgrading existing power lines as well as building new lines since the technology allows for the reduction of the number of support structures and/or a reduction of their height. Since its commercial introduction in 2005, ACCC® conductor has been selected for over 10,000 kilometers (6,214 miles) of projects in all environmental and operating conditions, including severe heat and ice environments, long span applications and high capacity corridors for the modern grid. ACCC® is a registered trademark of CTC Cable Corporation.
