Advantages Of Composite Insulators (1)
- May 10, 2018 -

Composite insulators

High strength and light weight. Composite insulators have a high strength-to-weight ratio, ie high specific strength. Its high mechanical strength is derived from the excellent mechanical properties of the glass fiber reinforced plastic mandrel. The tensile strength of the widely used FRP puller bars can reach over 1000 MPa, while the mandrel bar density is only about 2 g/cm3, so its specific strength is high. About 5 to 10 times higher quality carbon steel. At the same voltage level, the weight of the composite insulator is only 1/7~1/10 of the porcelain insulator.
