Copper wires

Copper wires generally include: multi-strand wire, single-strand wire, tinned wire, aluminum wire, enameled wire, wire twisted first and then plated, and tinsel; Multi-strand wire: The most commonly used, with the vast majority of wires adopting multi-strand wire, mainly for the following reasons: 1.Easy extrusion processing, making the wire soft; 2.Increase the heat dissipation area; 3. Increase tensile strength and flexural strength; 4. Reduce loss; (In large-cross-section power cables, the use of split conductors is not necessary, as the skin effect and proximity effect can increase cable current resistance and decrease current-carrying capacity) Meaning of common copper wire codes: a) Bare copper wire BA.AS or CU; b) Tin-plated wire TAS, TCU, or TS; c) Stranded and then plated wire TC-T; d) Copper foil wire (TSL); e) Copper-clad steel CCS, tinned copper-clad steel CP; f) Copper-clad aluminum (CCA), copper-clad aluminum-magnesium (CCAM), etc; g) Silver-plated copper wire SC h) Silver-plated copper-clad steel SCCS.
