铜包钢传输高频信号更好。

铜包钢产品既有钢的强度和韧性又有铜的导电性能，可焊性和耐腐蚀性，良好的高频性等，尤其是在高频下。

由于趋肤效应随着频率的增加而增大，因而铜包钢线的导电性能可与同截面积的铜线相比拟。具有比重轻、节铜材、造价低等优点，是传统铜线的换代产品。

Copper clad steel transmits high-frequency signals better.

Copper clad steel products not only have the strength and toughness of steel, but also have copper conductivity, weldability and corrosion resistance, good high frequency, especially at high frequency.

Because the skin effect increases with the increase of frequency, the conductivity of copper-clad steel wire can be compared with that of copper wire with the same cross-sectional area. It has the advantages of light proportion, copper material saving and low cost. It is a replacement product of traditional copper wire.
