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. Sometimes the braid is silver-plated. For better shield performance, some cables have a ...
RG-59 coaxial cable is commonly packed with consumer equipment, such as VCRs or digital cable/satellite receivers. Manufacturers tend to include only RG-59 cables because it costs less than RG-6 does. However, given the short lengths provided (usually 4–6 ft or 1.2–1.8 m), this is generally sufficient for its typical use.
Copper wires in a cable may be bare, or they may be plated with a thin layer of another metal, most often tin but sometimes gold, silver or some other material. Tin, gold, and silver are much less prone to oxidation than copper, which may lengthen wire life, and makes soldering easier. Tinning is also used to provide lubrication between strands.
'Twin and Earth' electrical cable to British Standard 6004, with twin 6 mm² conductors and uninsulated 2.5 mm² earth continuity conductor. Twin and earth (often written "T&E" and sometimes "T and E") cable is a colloquial name in the UK, Australia, New Zealand and other countries for a type of flat sheathed fixed mains electricity cable, containing two insulated current-carrying conductors ...
The cables are typically made with copper wires measured at 22 or 24 American Wire Gauge (AWG) (0.644 or 0.511 mm²), [5] with the colored insulation typically made from an insulator such as polyethylene or FEP and the total package covered in a polyethylene jacket.
Also, comparatively, more copper wire can fit in a given conduit than conductors with lower conductivities. This greater wire fill is a special advantage when a system is rewired or expanded. [17] Copper building wire is compatible with brass and quality plated screws. The wire provides connections that will not corrode or creep.
