Suspension insulator, also named as Polymer Suspension insulator,or composite Suspension insulator.What we said now, is Polymer Suspension insulator
The rod-shaped suspension composite/Polymer insulator is used for the rated voltage of the AC power system in the ordinary and polluted areas of 35kg~500kv, the overhead line of the frequency not exceeding 100Hz, the substation for drape and tensile strength. The ambient temperature of the insulator installation site is between -40 °C and +40 °C, and the altitude is not more than 1000 m.
It is especially used in dirty areas and can effectively prevent pollution flashovers. It is an alternative to porcelain insulators that are widely used today.
Polymer Suspension insulators, also known as composite suspension insulators, consist of a main structure consisting of a shed skirt, a glass fiber reinforced plastic (FRP) mandrel and an end fitting. The shed skirt is made of high temperature vulcanized silicone rubber, the FRP mandrel is glass fiber reinforced plastic material with glass fiber as reinforcing material and epoxy resin as base material, and the end fitting is carbon cast steel with outer surface coated with hot galvanized layer. Or carbon structural steel.
The structure of the Suspension insulator separates the mechanical strength from the outer insulation performance, and the mandrel and the shed skirt respectively bear mechanical and electrical loads, thereby integrating the urethane sheath material with excellent weather resistance, aging performance and mandrel material stretching machinery. Good performance. As part of the insulator structure, the fittings mainly serve to transfer mechanical stress and joint fixation.
