摘　　要：认为有线电视CATV电缆的发展正向第四代物理高发泡PE绝缘材料过渡。介绍了高物理发泡CATV电缆参数的计算公式。指出导电材料开始从纯铜线向铜包钢线、铜包铝线、铝镁合金线的发展,是新一代CATV电缆的革命性转变。The CATV cables are developing to the fourth generation physical foamingPE insulation material. The calculation formula of this new cable is presented. It is indicated that conduction materials are developing from pure copper wires to copper-covered steel wires,copper-covered aluminium wires and aluminium-magnesium alloy wires. This is the revolutionary trams-formation of the new generation CATV cable.
