According to the conductor of the core:Dick: there is no cable with copper core.Aluminum core cable does not do, aluminum belt.According to the core structure:Hard core is not conductive to the core: the core is a single, usually cylindrical.Does not include: the conductive cable multi-core copper wire winding summary.Method: according to the electrochemical depositionMethod: the use of non PVC cable with PVC plastic general.Methods: the power cable is not used for XLPE with XLPE, heat resistance and high conductivity of pvc.Layer by layer methodA power cable is not only one type of package: the power cable, such as: PVC / GuMethod: the electric cable layer is not wrapped outside the package with a layer of electronic layer wrapped in the way, such as PVC PVC / protection / chicken / chicken / or XLPE pvc.According to the number of cores:An unreliable core.Multi core cable: usually two core, three core or four core.
