Composite Technology Announces Continuing Sales Success in Indonesia For ACCC® Conductors

Irvine, CA – June 29, 2011 -- Composite Technology Corporation (CTC) (OTC Bulletin Board: CPTCQ) is pleased to announce two new orders for its subsidiary, CTC Cable Corporation from one of its two stranding partners in Indonesia, PT KMI Wire and Cable Tbk (KMI). CTC Cable Corporation will deliver the required ACCC® Core to KMI to enable KMI to fulfill these new orders.  Both projects are scheduled for delivery and installation this year.

CTC will deliver 141 kilometers of its 7.11 mm core to KMI for the manufacture of ACCC® Lisbon to be installed on the first circuit of the Pangkalan Berandan – Langsa Project.  A further 108 kilometers of 7.75 mm core will be delivered to KMI for use in manufacturing ACCC® Amsterdam Conductor to be installed on the Mranggen Incomer line. 

PLN Sumatra Grid, the sole provider of electricity in Indonesia selected ACCC® technology due to its superior overall performance in terms of capacity, sag and losses.

Acceptance of ACCC® conductors in Indonesia continues to  increase  significantly due to the efforts of our two stranding partners, PT KMI Wire and Cable Tbk (KMI) and PT Tranka Kabel as well as our representative in this  market.  The completion of these two projects will bring the total to five ACCC® conductor installations on PLN Sumatra’s Grid.

Stewart Ramsay, President of CTC Cable, after meeting with a delegation from KMI visiting California last week, noted that CTC’s relationship with KMI is strong and pledged his full support to the continued sales efforts in the market, stating, "We are pleased to receive these orders at a critical time for CTC.  They are the fruit of the careful nurturing of this market which has led to the increased adoption of ACCC® in Indonesia."

CTC Cable is the major global supplier of composite core conductor with over 10,000 kilometers (6,214 miles) of conductor ordered for over 160 commercial deployments on transmission and distribution lines.

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.
