Although the cost of steel strip with chrome-plated base belt is slightly higher, the steel strip can improve the corrosion resistance of the cable, improve the water seepage performance of the cable, and also improve the stripping strength of the armor.Moreover, in the bidding process of major telecom operators, the cable base band must be chrome-plated base band.
