    WK33828

    1. Scope

    1.1 This specification covers carbon fiber reinforced polymer matrix composite (core) strength members for use in reinforcing or supporting overhead electrical conductors. 1.2 This specification covers core diameters from 0.180 to 0.500 in. or 4.57 to 12.7 mm, inclusive. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Shaped wire compact concentric-lay-stranded aluminum conductors supported by a polymer matrix composite core have been on the market for about eight years. These conductors are similar to ACSS conductors in that they use fully annealed 1350 Al. The trapezoidal strands are wrapped around a polymer matrix composite core that consists of carbon fibers embedded in a polymer matrix surrounded by a shell of insulating material to keep the carbon and aluminum from coming into contact. With nearly 7000 miles of this type of conductor installed all over the world, a standard for the polymer matrix composite core is now needed.
