Common extension wire types are made up into standard multi-pair cables. Each conductor is covered with a PVC jacket, nominal 0.38 mm thick, and the pairs are individually twisted. Clear Mylar tape is then wrapped around the bundle of twisted pairs. A tinned-copper drain wire is laid over the bundle, which is covered with aluminium-backed Mylar tape to serve as an electrostatic shield. The drain wire provides a simple mechanical termination for the shield. The cable is then covered with a jacket of PVC approximately 1.1 mm thick.

As an added convenience, each standard cable contains an extra PVC-clad solid tinned-copper wire for use as an earth connection, or to complete a communication or signal circuit. The individual pairs are marked 1-1, 2-2, etc., for easy identification. Insulation will withstand temperatures up to 105°C.
