SINOFUJI Silicon rubber cover also in the name of power line sleeve design, ease of installation. Use silicon rubber material, anti-aging, corrosion resistance, with good resistance to corona resistance, high temperature performance, especially suitable for the protection of the bare wire. Silicon rubber cover power line sleeve widely used in substation protection works and railway catenary system, a significant effect in the cross-lines.
