The cable core consists of slit and bonded flat gray ribbon cable. The core is folded and twisted into a round format before being taped with either polyester (23149) or aluminum/polyester (23122) tape. For dual shielded versions, cable is then braided. The flat ribbon cable is built with 28(7/36) AWG conductor size. The core is jacketed in black PVC. The process for making great flat cable is simple. In flat cables, the key to low cost termination is ease of the termination during the IDC process with consideration to minimize scrap.
