Polymer Distribution Insulators
Polymer distribution insulators is composed of fiberglass epoxy resin lead-out rod, silicon rubber housing and hardware.
1.Technical data of polymer distribution insulators
Rated mechanical bending load
Min nominal creepage distance
1min power frequency wet withstand voltage (kV)
Full wave lightning impulse withstand voltage peak value (kV)
2.Features of polymer distribution insulators:
1.The arcing corona ring well distributes the electric field along the polymer distribution insulators’s axe to prevent corona phenomenon and secure the insulator from heavy damage in end fitting in case of flashover.
2.The end fitting and FRP rod are connected with imported end-fitting crimping equipment ,ensures the mechanical performance of the product.
3.The unique end fitting sealing structure improves product sealing reliability.
4.The strict inspection measures ensure the perfect quality of every polymer distribution insulators.
