300kN insulators UG300B/195/480D double-umbrella Suspension Electrical Glass Insulator

300kN double-umbrella disc suspension glass insulator UG300B/195/480D

Structural composition:

The product consists of an iron cap, tempered glass parts, and steel feet, and is integrated with cement adhesive. This product adopts the most advanced cylindrical head structure internationally, characterized by small head size, light weight, high strength, and large creepage distance. Can save metal materials and reduce line costs. To meet the needs of live working, traditional domestic structural shapes are used on the brim of the hat.
