Communications Cable Direct-buried cable Flexible cables Heliax cable Non-metallic sheathed cable (or nonmetallic building wire, NM, NM-B) Metallic sheathed cable (or armored cable, AC, or BX) Multicore cable (consist of more than one wire and is covered by cable jacket)

Portable cord – Flexible cable for AC power in portable applications Ribbon cable – Useful when many wires are required. This type of cable can easily flex, and It is designed to handle low-level voltages. Shielded cable – Used for sensitive electronic circuits or to provide protection in high-voltage applications. Single cable (from time to time this name is used for wire) Submersible cable Twinax cable Twin-lead – This type of cable is a flat two-wire line. It is commonly called a 300 Ω line because the line has an impedance of 300 Ω. It is often used as a transmission line between an antenna and a receiver (e.g.,
