Classification3.1 For the purpose of this specification, conductors are classified as follows:3.1.1 Class AAFor bare conductors usually used in overhead lines.3.1.2 Class AFor conductors to be covered with weather-resistant materials, and for bare conductors where greater flexibilitythan i
10、s afforded by Class AA is required. Conductors indicated for further fabrication into tree wire or to be insulated and laidhelically with or around aluminum or ACSR messengers, shall be regarded as Class A conductors with respect to direction of layonly (see 6.3).1 This specification is under the ju
