Electrically conductive casing for electrical conductor, has base consisting of aluminum and aluminum alloy, and sealing layer, which is made of inorganic silk containing compound, applied as external layer

摘要

The casing (13) has a base (18), which is provided with a surface layer composition, where the base consists of aluminum or aluminum alloy. An adhesive in the form of chemical nickel and a corrosion protection layer and a metallic passivation layer are provided as the layer composition. The corrosion protection layer is formed by zinc cobalt ion alloy. The passivation layer is a composition of trivalent chromium. A sealing layer from inorganic silk containing compound is applied as an external layer.
