|dielectric, not self-supported, optical attached cable
Note 1 to entry: OPACs can be used with one of the following attachment methods:
· wrapped, known as an all-dielectric (wrap): using special machinery, a lightweight flexible non-metallic cable is wrapped helically around either the earth wire or the phase conductor;
· lashed: non-metallic cables are installed longitudinally alongside the earth wire, the phase conductor or on a separate support cable (on a pole route) and are held in position with a binder or adhesive cord;
· spiral attached: similar to the lashed cables except that the method of attachment involves the use of special preformed spiral attachment clips.
Note 2 to entry: OPAC cable designs are not covered by this specification.
