Silane-crosslinkable polyethylene compounds and copper-clad steel wire are commonly used in the production of coaxial cables. The silane-crosslinkable polyethylene compound is used as the insulation material for the inner conductor of the coaxial cable, while the copper-clad steel wire is used as the outer conductor or shielding. The copper-clad steel wire is preferred over pure copper wire due to its higher strength and better durability. It is also more cost-effective than pure copper wire. The combination of these two materials results in a high-performance coaxial cable that can be used in a variety of applications, including telecommunications, television broadcasting, and computer networking.
