Abstract
A cable (11) is provided comprising a steel cord (12) and a polymer material (15). The steel cord (12) has a diameter less than 2.5 mm, and is coated with the polymer material (15). The cable (11) has a permanent elongation of less than 0.05% at a permanent force of 50 N, after being subjected to a force of 450 N. Further, a window elevator system (300) comprising such a cable (11) is provided.
Claims22
A cable, comprising:
- a steel cord comprising an outer jacket layer having a jacket center circle, and
- a thermoplastic material having a shore D hardness between 60 and 100,
- wherein said steel cord has an optical diameter less than 2.5 mm, said steel cord being coated with said thermoplastic material, at least part of said thermoplastic material being provided radially inwards of said jacket center circle, said thermoplastic material being chemically anchored through an intercalated bi-functional adhesion promoter to said steel cord, and said cable has a permanent elongation of less than 0.05% at a permanent force of 50 N after being subjected to a force of 450 N.
A window elevator system, comprising:
- a clamping system,
- a rotating device,
- at least one guiding part, and
- a cable, said cable being bent around guiding elements,
- wherein said cable comprises a steel cord comprising an outer jacket layer having a jacket center circle, and a thermoplastic material having a shore D hardness between 60 and 100, wherein said steel cord has a diameter less than 2.5 mm, said steel cord being coated with said thermoplastic material, at least part of said thermoplastic material being provided radially inwards of said jacket center circle, said thermoplastic material being chemically anchored through an intercalated bi-functional adhesion promoter to said steel cord, and wherein said cable has a permanent elongation of less than 0.05% at a permanent force of 50 N after being subjected to a force of 450 N.
