Galvanized steel cable
Galvanized steel cable is a kind of iron and steel products twist together with galvanized steel wire.
There are four section structure including 1×3,1×7,1×19,1×37
Characteristic of galvanized steel cable:
- Good flexibility
- Good stability
- Good reliability
- High strength
Technological requirement of galvanized steel cable:
- Steel wire (including central wire) should be the same diameter, the same strength, the same level of zinc.
- diameter and twist pitch should be uniform cut loose.
- Steel wire should be tightly twisted should be staggered, breaking and bending.
4.Steel cable should be straight, soft, small residual stress expansion should not be s-shaped.
5.No joint for 1×3 structure and overhead ground wire, steel wire connector of other types should use butt, the spacing between any two joint shall not be less than 50m joints should do anti-corrosion treatment.
Surface quality of galvanized steel cable:
- Steel surface should not be stacked marks, scratches, broken, crushed and hard bending defects.
- Surfaces must be free of oil, dirt, water and other impurities.
- Galvanized wire surface layer split should be uniform and continuous, no cracks and spalling. But the surface of the zinc layer is allowed to have a small amount of flash point and white thin layer and color difference.
Application of galvanized steel cable:
Widely used for messenger cable, guy wire, core wire or strength member, can also be used as earth wire/ground wire, barrier cable on both sides of the road ,structure cable in building structure.
