Porcelain cutout insulator is usually used in 7.8kv, 15kv, 27kv, 20kv, 34.5kv and 28kv power lines to protect the line circuit.

The features of Porcelain cutout insulator
◆ Rated current: 100A, 200A, 300A
◆ Consists of cutout body, fuse holder and fuse element
◆ Made from porcelain or polymer materials
◆ Cutout/ arrester combo

The body of Porcelain cutout insulator has an open "C"-shaped frame that supports the fuse holder and a ribbed porcelain or polymer insulator that electrically isolates the conductive portions of the assembly from the support to which the insulator is fastened.

Porcelain cutout insulator is used as fuse, also called fuse cutout insulator or drop-out fuse cutout insulator for electrical systems.
