I. Overview

Used for insulation and fixed conductors in overhead power lines with a rated voltage of less than 1000V for DC or AC power frequency. According to their structural types, they are divided into low-voltage needle insulators, low-voltage butterfly insulators, and low-voltage spool insulators. The surrounding environment temperature of its installation and use location is -40 ℃~+40 ℃, and the altitude does not exceed 1000m.
