Abstract
A non-magnetic stainless steel wire with an adherent corrosion resistant coating is disclosed. The surface of the non-magnetic stainless steel is pre-treated so as to be sufficiently free from oxides and form a good adhesion with the above corrosion resistant coating. The non-magnetic stainless steel wire is used as a armoring wire for a power cable for transmitting electrical power.
Claims14
A power cable for transmitting electrical power, comprising:
- an armouring layer comprising non-magnetic stainless steel wire and magnetic low-carbon steel wire,
- said non-magnetic stainless steel wire comprising a corrosion resistant coating on the surface of the non-magnetic stainless steel, wherein said surface is pre-treated, the pre-treated surface being sufficiently free from oxides and adhering to said corrosion resistant coating, said corrosion resistant coating is zinc and/or zinc alloy, and said corrosion resistant coating is present in an amount of 20 g/m2 to 600 g/m2, and
- said magnetic low-carbon steel wire comprising a corrosion resistant coating.
