Non-rotating steel wire rope
Uses :applied to mechanical pulling and tensioning release conductors ,unsuitable to pulling ropes for small diameter winch .
Non-rotating Steel Wire Rope
Non-rotating steel wire ropes are braided with fine-quality zinc-plated wires (1/8/12* 19W, 1/8/12* 25F1),which have the features listed below;
1. The angle of rotation of the wire ropes under the tensile strength in a natural state is equal to 0 and their resultant torque is equal to 0.
2. The wire ropes,flexible in use,are free from knotting,
interwinding,strand breaking and Wire hooks,when the tension is released.
Non-rotating steel wire rope wire ropes are mainly used for
1.Electric power lines traction,tensional paying-off of leading ropes or used as a dragging rope for Paying-off. However,the diameter of the barrel core in the winch should be 15 times or over greater than that of the wire rope.
2 Used as lifting ropes instead of common wire ropes within the range of tension permissible.
Structural forms of non-rotating sttel wire ropes (in cross section)
1 Four-sided eight strands
2 Four-sided twelve strands
3 Six-sided twelve strands
