2. SY control cable - Wikipedia

   en.wikipedia.org/wiki/SY_control_cable

   An SY control cable is a flexible instrumentation electrical cable designed for measuring, control or regulation in the field of process automation. [1] It is a flexible multicore cable, with (class 5) [which?] copper conductors and a galvanised steel wire braid (GSWB) for mechanical protection.

3. Coaxial cable - Wikipedia

   en.wikipedia.org/wiki/Coaxial_cable

   Many conventional coaxial cables use braided copper wire forming the shield. This allows the cable to be flexible, but it also means there are gaps in the shield layer, and the inner dimension of the shield varies slightly because the braid cannot be flat.

4. RG-59 - Wikipedia

   en.wikipedia.org/wiki/RG-59

   RG-59/U is a specific type of coaxial cable, often used for low-power video and RF signal connections. The cable has a characteristic impedance of 75 ohms, and a capacitance of around 20pF/ft (60pF/m). [1]

5. Twisted pair - Wikipedia

   en.wikipedia.org/wiki/Twisted_pair

   It is less flexible than stranded cable and is more prone to failure if repeatedly flexed due to work hardening. Stranded cable is used at patch panels and for connections from wall ports to end devices (patch cord or drop cable), as it resists cracking of the conductors. Connectors are designed differently for solid core than for stranded.

6. Electrical cable - Wikipedia

   en.wikipedia.org/wiki/Electrical_cable

   Electrical cable diagram Flexible mains cable with three 2.5 mm solid copper conductors. An electrical cable is an assembly of one or more wires running side by side or bundled, which is used as an electrical conductor to carry electric current.

7. Copper conductor - Wikipedia

   en.wikipedia.org/wiki/Copper_conductor

   They are relatively rigid, do not bend easily, and are typically installed in permanent, infrequently handled, and low flex applications. Stranded wire has a group of copper wires braided or twisted together. Stranded wire is more flexible and easier to install than a large single-strand wire of the same cross section.
