Stranded 6201 aluminum alloy conductors shown in this section of data are classified as follows: Class AA For bare conductors usually used in overhead lines. Class A For conductors to be covered with weather-resistant materials and for bare conductors where greater flexibility is required. Compact strand conductor for use in bare overhead applications or for use with weather-resistant coverings or insulations is also available. Classes refer to stranding and are an indication of relative conductor flexibility, AA being the least flexible, C the most flexible
PVC/XLPE copper power cable is used to transmit and distribute power in power transmission and distribution system. It is generally applied to the fields including power, construction, mines, metallurgy, petrochemical industry and communication in complete replace of oil immersed paper insulated power cable and in partial replace of PVC insulated power cable.
