In the flow state equation of a non-Newtonian fluid, if 1< n < ∞, it is called dilatational flow. The relation curve of the shearing stress and the shearing rate passes through the origin, and bends upwards in the direction deviating from the epsilon axis. The apparent viscosity η gradually increases with increasing shear stress or shear rate. The visual expression is as follows: when encountering extreme transient impact forces, the dilatant non-newtonian fluid becomes very stiff and thus resists impact. By utilizing the properties, the non-Newtonian fluid is arranged in a plurality of cables to improve the impact resistance of the cables, so that the internal cable cores can be effectively protected.
