Tips for using Shackle Insulator products

Shackle Insulator products mandrels are characterized by high strength and high specific strength.
Shackle Insulator products mandrels are characterized by high strength and high specific strength. Its tensile strength can reach 7000MPa, and its specific strength is 5 times that of high-quality carbon steel. Some regions and departments propose to use Shackle Insulator products, whose mechanical strength is one level higher than that of traditional porcelain and glass insulators. For example, the use of porcelain insulators is 160kN, while the use of Shackle Insulator products is 210kN.
In fact, when the load is less than 40% of the rated mechanical load, the reliability of operation can be guaranteed. Therefore, Shackle Insulator products can be selected according to the method of porcelain insulators without increasing the mechanical load value. The test of mandrel load deflection shows that Shackle Insulator products have good bending resistance, good resistance to galloping and breeze vibration. When used in a tension tower, it can bear a certain bending moment. How different the changes in mechanical properties of products with different end connection structures will be in long-term operation still needs in-depth research.
