15 kV,110 kV BIL,D-shape Standard Type C Polymer Cutout with a 100A, 10kAIC Fuseholder
The Standard Type C Polymer Cutout is an overhead distribution protection device designed to provide reliable overcurrent and fault isolation in medium-voltage power line construction. Engineered for utility and substation applications, it integrates a polymer-housed insulator with a dropout fuse mechanism to safeguard transformers, capacitor banks, and lateral feeders against transient and sustained faults.
The polymer housing offers superior contamination performance and enhanced resistance to UV radiation, tracking, and environmental degradation compared to traditional porcelain designs. Its dropout action provides visible isolation, ensuring safe line sectionalizing and simplified maintenance procedures in distribution networks.
