Abstract
A push-pull steel cable (10) comprises a core (12) and an outer layer of filaments (16) twisted around the core (12). The cable (10) is provided with an external coating (20) of polyethylene terephthalate. The coating (20) gives to the cable (10) a good resistance against corrosion, a good weatherability, a good adhesion and adhesion retention and a friction resistance which is comparable to the friction resistance of a cable with a nylon coating. The cable (10) can be used as a brake cable, a shifting lever cable or a window elevator cable.
Claims13
A push-pull inner steel cable for sliding within a casing, said inner steel cable comprising:
- a core;
- and
- an outer layer of filaments twisted around the core, the inner steel cable being provided with an external coating of polyethylene terephthalate around and fixed to said outer layer of filaments.
An inner steel cable comprising a core and an outer layer of filaments twisted around the core, the inner steel cable being provided with an external coating of polyethylene terephthalate, wherein the cable further comprises a super absorbent powder between the core and the outer layer.
An inner steel cable comprising a core and an outer layer of filaments twisted around the core, the inner steel cable being provided with an external coating of polyethylene terephthalate, wherein the filaments have an individual metal coating of zinc or a zinc alloy.
An inner steel cable comprising a core and an outer layer of filaments twisted around the core, the inner steel cable being provided with an external coating of polyethylene terepthalate, wherein the coating thickness allows the irregularities of the outer layer to be seen.
