This specification covers carbon fiber composite core/thermoset (CFCC/TS) matrix for use in reinforcing or supporting overhead electrical conductors. It provides requirements for CFCC/TS materials and manufacture, including tensile strength, glass transition temperature, and minimum bending diameter. This specification also applies to classes of CFCC/TS, test classifications and number of tests and retests, actual density of the CFCC/TS, minimum thickness of the galvanic protection barrier layer, joints, workmanship, finish and appearance, inspection, certification, and packaging and package material. The tests covered by this specification are: tensile test and glass transition temperature test, bending test, dye penetrant testing after bending test, tensile test after bending test, heat exposure test, and heat/stress test.

ORDER

Scope

1.1 This specification covers carbon fiber reinforced thermoset matrix composite core strength members for use in reinforcing or supporting overhead electrical conductors.

1.2 This specification covers carbon fiber core diameters from 0.180 to 0.500 in. [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 non-conformance 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.
