345kV 111kN polymer suspension insulator

345kV 111kN polymer suspension insulator was used on transmission line and installed in suspension steel tower. This type polymer insulator used to suspend conductor or wire. This type 345kV 111kN polymer suspension insulator was designed according to project requirement. One side of fitting is ball and the other metal fitting is Y clevis.

Grading ring for 345kV 111kN polymer suspension insulator
Normally, for above 110kv polymer insulator, it should be assembled with arcing horns or grading ring. 345kV 111kN polymer suspension insulator has been equipped with two aluminum grading rings. The grading rings can be installed by hot stick method or removed without disassembling the insulator and hardware assembly.

End fitting and rod of 345kV 111kN polymer suspension insulator
End fitting material was forged steel; hot-dip galvanized and permanently sealed to prevent moisture and foreign materials from entering the end fitting-rod interface.
Rod material was epoxy reinforced fibre glass matrix and manufactured by pultrusion processing.
